Aeristech launches new 48V electric supercharger
July 31, 2015
UK-based Aeristech has introduced a new 48V electric supercharger capable of continuous operation at high boost levels. Independently validated by Ricardo and MAHLE Powertrain UK, the technology provides greater efficiency and easier packaging than a mechanical supercharger or a two-stage turbocharger.
Aeristech said it overcame the thermal management issues that can restrict other electric boosting devices currently available on the market to only transient operation by using permanent magnet motor technology in place of the more usual switched reluctance type. This has been made cost-effective by developing a patented control and switching technology that enables the use of many cost-competitive components.
Delphi invests in Tula; Dynamic Skip Fire cylinder deactivation
July 30, 2015
Delphi has made a minority investment in Tula Technology, the developer of Dynamic Skip Fire cylinder deactivation technology. (Earlier post.) The software-enabled powertrain technology integrates advanced digital signal processing with advanced powertrain controls to create a variable displacement engine.
DSF allows the engine’s cylinders to fire or skip (deactivate) on a continuously variable basis. In independent tests, DSF has improved fuel efficiency by up to 17% as measured on a CAFE basis when compared to a vehicle (V8 engine) that does not have cylinder deactivation. GM Ventures made an equity investment in Tula in 2012.
Roland Berger study explores need for consolidation in vehicle electronic architectures
July 29, 2015
In a new study, Roland Berger Strategy Consultants explores the strategy of module consolidation as a solution for the feature- and function-driven increasing complexity of vehicle electronic architectures.
Consumers increasingly expect the latest and greatest in electronics and safety when purchasing a car, regardless of type. Whether it’s an instrument cluster with a graphics rich, fully reconfigurable display or a lane departure warning system, a tremendous amount of processing power and electronic communication is required. The current approach to adding these features to vehicle’s electric/electronic (E/E) architectures is generally “ad-hoc”—i.e., simply adding a new ECU every time a new vehicle feature requires processing power. This has resulted in vehicles with as many as 100 ECUs and more than 100 million lines of code in ultra-luxury cars.

New safety test environment for high-speed flywheels for energy storage systems; new high-speed imaging techniques
July 07, 2015
The Ricardo-led FlySafe research collaboration—involving a range of leading industrial and academic partners including the University of Brighton’s Centre for Automotive Engineering—has delivered an innovative flywheel safety test environment to enable the development of next-generation flywheel energy storage systems.
The FlySafe project is investigating the potential failure mechanisms and behaviors of high-speed flywheel systems. Operating at extremely high rotational speeds, these systems offer a practical and potentially cost-effective mechanical means of saving fuel and reducing carbon emissions through the mechanical storage and reuse of energy in applications such as regenerative braking. The FlySafe research aims to provide best-practice design guidelines for the safety containment systems of high speed flywheels, appropriate for commercial mass market deployment of these systems. A key output of the project in this respect will be a proposed BSI flywheel safety standard.
Free piston/ORC system for automotive waste heat recovery being tested at University of Brighton
June 18, 2015
A prototype automotive waste heat recovery system has been fired up on a recently commissioned test rig at the University of Brighton. The organic Rankine cycle test rig uses a novel linear free piston expander from Libertine (earlier post) to overcome the technical and economic barriers to using Rankine cycle technology for automotive waste heat recovery.
Initially configured to simulate heavy duty truck applications, the 20 kWe system can be scaled down to 3 kWe for light duty trucks and passenger cars. Libertine expects the results from rig tests to confirm the system’s potential to convert the high grade heat in the exhaust into electrical power, which can contribute to either powertrain or auxiliary loads.

US$7.5M JOSPEL project to develop energy efficient climate control for EVs; leveraging Joule and Peltier effects
June 03, 2015
A trans-European collaboration aims to develop a novel energy efficient climate control system to help reduce the energy used for passenger comfort in electric vehicles by at least 50%. Even in today’s modern electric vehicles, a lot of energy is wasted on heating or cooling, in turn limiting the already relatively short range by further draining the battery capacity.
The aim of the €6.7-million (US$7.5-million) JOSPEL project is to develop an efficient, electrical climate control system using an integrated approach that combines the application of the Joule and Peltier effects; efficient insulation of the vehicle interior; energy recovery from heat zones; increased battery life as a side effect of thermal management; reduced battery energy consumption via the integration of Peltier cooling; innovative automated and eco-driving strategies; and the electronic control of power flows.
Toyota to explore integration of SmartDeviceLink Technology with Ford subsidiary; open source version of Ford AppLink
Toyota Motor Corporation has reached an agreement with Ford Motor Company to explore collaboration with Livio, a Ford subsidiary acquired in 2013 (earlier post), for the implementation of SmartDeviceLink (SDL) technology in future Toyota and Lexus vehicles.

Those apps can be easily accessed using voice recognition, display screens, and dashboard controls. Besides its seamless ease of operation, the benefits of SDL technology include the ability for developers to design an app only one time, yet have it work across multiple infotainment systems. This saves development time and allows apps to be introduced more quickly to a wider audience.
DARPA program integrates non-mechanical optical scanning tech on microchip; new class of low-cost, miniature LIDAR could support autonomous vehicle apps
May 30, 2015
DARPA’s Short-range Wide-field-of-view Extremely agile Electronically steered Photonic EmitteR (SWEEPER) program has successfully integrated breakthrough non-mechanical optical scanning technology onto a microchip. Freed from the traditional scanning architecture of gimbaled mounts, lenses and servos, SWEEPER technology has demonstrated that it can sweep a laser back and forth more than 100,000 times per second, 10,000 times faster than current state-of-the-art mechanical systems.
SWEEPER technology can also steer a laser precisely across a 51-degree arc, the widest field of view yet achieved by a chip-scale optical scanning system. These accomplishments could open the door to a new class of miniaturized, extremely low-cost, robust laser-scanning technologies for LIDAR and other uses. Applications can include autonomous vehicle technology.

Review of research suggests inconclusive support for fuel consumption benefits of catalyzed EGR
May 18, 2015
Conflicting evidence does not support making a firm conclusion on the fuel consumption benefit of catalysed Exhaust Gas Recirculation (EGR), according to a review of current studies by a team at the University of Bath (UK). In catalyzed EGR, a catalyst alters the chemical composition of the exhaust gas mix before its reintroduction to the engine. As an example, one study found a decrease in fuel consumption of up to 2%, while another found an increase of 1.5%-3.5%.
According to the review, the conversion of HCs, CO, and NO in the exhaust gas by the catalyst can result in up to a 4.5% reduction (in extreme cases) in the calorific value of the charge for catalyzed EGR when compared to equivalent operation with un-catalyzed EGR; this reduction in calorific value has a negative impact on the achievable BSFC. An open access paper on the study (an update of an earlier version published late last year) appears in the International Journal of Engine Research.
Volvo Trucks introduces automatic all-wheel drive for improved driveability and fuel economy
May 13, 2015
Volvo Trucks is introducing automatic all wheel drive—a feature it calls Automatic Traction Control—on construction trucks. ATC activates the drive on the front axle automatically when in motion, if the truck risks getting stuck—i.e., when the rear wheels lose traction on slippery or soft ground. The driver enjoys improved maneuverability, and the owner benefits from lower fuel consumption and less wear and tear on the truck.
The solution consists of software connected to the wheel speed sensors which detect and control wheel drive. When a rear wheel starts to slip, the power moves automatically to the front wheels without the truck losing torque or speed. A dog clutch activates the front-wheel drive in just half a second. The clutch is lighter and has fewer moving parts than a traditional solution with permanent all-wheel drive. If the driver encounters particularly rough ground, then it is possible to manually lock the other differentials at both front and rear.
Ford exploring cylinder deactivation for 1.0L EcoBoost; testing shows up to 6% fuel efficiency improvement
May 12, 2015
Ford, in collaboration with the Schaeffler Group, is investigating different cylinder deactivation approaches on its award-winning 1.0-liter, three-cylinder EcoBoost engine. On-road tests using a working prototype showed fuel efficiency improvements of up to 6%, according to Dr. Andreas Schamel, director, Ford Global Powertrain, Research & Advanced Engineering in Vienna last week.
For the test, the engineers also developed a new dual mass flywheel. This enabled cylinder deactivation to take place at a wider range of engine loads and speeds, and helped minimize noise, vibration and harshness levels.
Audi power-dense 2.5L TFSI engine with electric biturbo delivers 591 hp from 2,480 cc; 48V subsystem for the turbo
May 09, 2015
At the Wörthersee festival, Audi is showcasing the Audi TT clubsport turbo technology concept equipped with a new 2.5 TFSI gasoline engine with an electric biturbo (earlier post) that delivers 441 kW (591 hp) and 650 N·m (479.4 lb-ft), with acceleration from 0 to 100 km/h (62.1 mph) in 3.6 seconds. Peak torque is available from 3,000 to 7,000 rpm. Power is transferred via a manual six-speed transmission.
While production car engines with this level of output are available from a number of mainstream OEMs, the displacement of the Audi engine is about half or less that of the others, resulting in a very power- and torque-dense unit. The five-cylinder, 2,480 cc engine produces 178 kW (239 hp) and 262 N·m (193 lb-ft) per liter of displacement. By comparison:
OEMs shifting towards onboard chargers > 6 kW for EVs; lower output chargers to remain dominant through 2020
May 05, 2015
Most battery and plug-in hybrid electric vehicle (PHEV) manufacturers in Europe and the US have been adopting onboard chargers with a power output between 3 to 3.7 kilowatts (kW). Now, EV manufacturers are moving towards onboard chargers with a power output greater than 6.6 kW to reduce charging time.
While high-end PHEVs are contributing to this trend, lower-end models in this segment are still using 3.7 kW onboard chargers. Consequently, onboard chargers with power ratings between 3 to 3.7 kW are expected to remain dominant, accounting for 62% of sales even in 2020, according to new analysis from Frost & Sullivan.
HRL Labs video demonstrates principle of thermal battery based on advanced metal hydrides for EV heating and cooling
April 30, 2015
In 2011, the Advanced Research Projects Agency - Energy (ARPA-E) awarded $2.7 million to a team comprising researchers from the University of Utah, HRL Laboratories and GM Global R&D for a project to develop a new generation of high-density thermal battery based on advanced metal hydrides. (Earlier post.) The goal of the project, part of ARPA-E’s HEATS (High Energy Advanced Thermal Storage) portfolio, was to develop a compact thermal battery for climate control in electric vehicles. Such a thermal battery would provide heating and cooling without draining the electric battery, in effect, extending the driving range of EVs per electric charge.
As described in a paper in press in the Journal of Alloys and Compounds, the developed system uses a pair of thermodynamically matched metal hydrides as energy storage media: (1) catalyzed MgH2 as the high temperature hydride material, due to its high energy density and enhanced kinetics; and (2) TiV0.62Mn1.5 alloy as the matching low temperature hydride. HRL has now released a video demonstrating the principle behind the work on thermal battery technology.
Visio.M partners showcasing energy efficient passenger climate control for EVs
April 15, 2015
As part of the German Federal Ministry for Education and Research (BMBF) collaborative project Visio.M (earlier post, earlier post), scientists of the TU München have developed an energy efficient solution for passenger climate control in EVs. The researchers are presenting the results of their work, as implemented in the Visio.M prototype vehicle, in the German government stand at the Hannover Messe.
In a combustion-engined vehicle, waste heat could be used to heat the vehicle passenger compartments directly. Many electric vehicles simply took over concepts from the combustion engined vehicles—e.g., a heater and an air conditioner. However, the energy drain of this approach can put a noticeable dent in vehicle range. The Visio.M researchers thus took a new look at all potential solutions, considering their efficiency, comfort and cost.

SABIC introduces novel thermoplastic roof fairing concept for 3% improvement in heavy-duty truck fuel economy
March 26, 2015
SABIC has introduced a thermoplastic roof fairing concept that can potentially reduce annual fuel consumption of a heavy-duty truck by at least 3%. SABIC’s design concept is aerodynamically optimized to deflect air by accelerating airflow through and across the top and sides of the roof fairing. The result is a significant drop in drag, up to 5.9%, improving the aerodynamic performance and fuel efficiency of a heavy-duty truck.
SABIC’s new thermoplastic roof fairing concept incorporates air ducts to reduce front end pressure and accelerate airflow both over the surface and through the fairing itself. Conventional roof fairings, in contrast, achieve aerodynamic efficiencies simply by maximizing airflow over smooth, closed surfaces.
New ABB Azipod D for electric marine propulsion requires 25% less installed power, boosts flexibility
March 25, 2015
|Azipod D. Click to enlarge.|
ABB has introduced a new offering, Azipod D, to its line of Azipod marine electric propulsion systems. This new product will allow a wider range of vessel types to benefit from the proven reliability and flexibility that have made Azipod the leading propulsion system across numerous ship types.
Azipod Propulsion is a gearless steerable propulsion system in which the electric drive motor is in a submerged pod outside the ship hull. A ship with Azipod Propulsion does not need rudders, long shaftlines or stern transversal thrusters. This new Azipod D provides designers and ship builders with increased design flexibility in order to accommodate a wide range of hull shapes and propeller sizes, as well as simplicity of installation. The Azipod D requires up to 25% less installed power. This is partly due to the fact that the new hybrid (air and water) cooling helps reduce the thruster’s weight and directs more power toward propulsion of the ship, not cooling requirements. The performance of the electric motor is increased by up to 45%.

Extensive materials genome modeling study suggests best adsosrbent materials for natural gas storage already designed; 70% of ARPA-E target
February 03, 2015
Using a materials genome approach, a collaboration between EPFL, the University of California at Berkeley, Rice University, the Georgia Institute of Technology, Northwestern University, Lawrence Berkeley National Laboratory, and the Korea Advanced Institute of Science and Technology has searched for high-performance adsorbent materials to store natural gas in a vehicular fuel tank.
In their study, published in the RSC journal Energy & Environmental Science, they simulated more than 650,000 designs for nanoporous materials. They found that the best candidates for natural gas storage have already been designed—but that those best materials meet only 70% of the Advanced Research Projects Agency - Energy (ARPA-E) targets for natural gas storage on vehicles.

The recalls will provide vehicle owners with a new remedy after the manufacturers’ original attempts to fix the defects proved ineffective in some vehicles.
Bosch completes acquisition of ZF’s share of ZF Lenksysteme JV; electric steering systems for fuel efficiency, ADAS and automated driving
January 30, 2015
The Bosch Group has completed its acquisition of ZF Friedrichshafen AG’s 50-percent share in the joint venture ZF Lenksysteme GmbH (ZFLS). Bosch now owns all shares in the formerly 50:50 joint venture, formed in 1999. It will be incorporated into the Bosch Group as a new division with the name Robert Bosch Automotive Steering GmbH.
ZFLS is a leading manufacturer of electric steering systems, with which it currently generates around 60% of its sales, which were around €4.1 billion (US$4.6 billion) in 2013. Alongside its potential to save up to 0.8 liters of fuel per 100 kilometers, electric steering is the basic technology required to realize a number of assistance systems in cars as well as automated driving.
Study finds vertical force of in-wheel switched reluctance motors deteriorates vehicle stability and comfort
January 27, 2015
In a study investigating switched reluctance motors (SRMs) for in-wheel motor applications, researchers at Chongqing University in China have found that the vertical component of the residual unbalanced radial force of the motor deteriorates the lateral and anti-rollover stabilities of the vehicle in addition to having a considerable impact on vehicle comfort. (The unbalanced radial force is the radial force difference between a pair of opposite stator poles.)
In their paper, published in the Proceedings of the Institution of Mechanical Engineers, Part D: Journal of Automobile Engineering, they suggest that a control method addressing these issues will be needed if SRMs are to see use in in-wheel applications. In an earlier paper, members of the team had proposed the use of an FxLMS (filtered-X least mean square) controller based on active suspension system to generate controllable force to suppress the vibration caused by SRM vertical force. In that paper, they found that utilizing active suspensions could reduce the effect of SRM vertical force on suspension performance.

Toyota bringing vehicle-infrastructure cooperative systems to some new models in Japan in 2015
November 26, 2014
Starting next year, some of Toyota Motor Corporation’s new models will be compatible with advanced vehicle-infrastructure cooperative systems that use a wireless frequency reserved for Intelligent Transport Systems (ITS). This compatibility will be offered as an option for the “Toyota Safety Sense P” active safety package that will be made available in 2015 on select new models sold in Japan.
The systems will use the dedicated ITS frequency of 760 MHz for road-to-vehicle and vehicle-to-vehicle communication to gather information that cannot be obtained by onboard sensors. At intersections with poor visibility, information about oncoming vehicles and pedestrians detected by sensors above the road will be conveyed via road-to-vehicle communication, and information about approaching vehicles will be conveyed via vehicle-to-vehicle communication, with audio and visual alerts warning drivers when necessary.
IBM Research and ASELSAN to collaborate on metal-air battery technology, focusing on EVs; mm-wave ICs
November 25, 2014
IBM Research and Turkish defense industry technology company ASELSAN (Askerî Elektronik Sanayii, Military Electronic Industries) have signed collaborative development agreements concerning research and development of metal-air battery technologies and millimeter wave integrated circuits. The companies will work together on these projects, and through these efforts ASELSAN will enhance its in-house research and development activities.
In 2009, IBM and its partners launched a multi-year research initiative specifically exploring rechargeable Li-air systems (one type of metal-air battery): “The Battery 500 Project”. (Earlier post.) The “500” stands for a target range of 500 miles/800 km per charge, which translates into a battery capacity of about 125 kWh at an average use of 250 Wh/mile for a standard family car.
Tsinghua team devises in-cycle control method for diesel LTC using detection of Start of Combustion
Low temperature combustion (LTC) refers to a broad range of in-cylinder combustion strategies for the reduction of NOx emissions from diesel combustion; NOx is formed primarily by a thermal mechanism, which production rates increasing exponentially with temperature. LTC strategies reduce combustion temperatures by the dilution of the in-cylinder combustible mixtures, either with excess charge gas to create more fuel-lean mixtures, or with moderate to high levels of EGR.
However, challenges remain in diesel low temperature combustion implementation due to combustion inconsistency or instability. To address this, a team from Tsinghua University has devised an in-cycle combustion feedback control method based on the detection of the Start of Combustion (SOC) in diesel LTC. A paper describing their method is published in the journal Applied Energy.
Bus maker Alexander Dennis to fit GKN Gyrodrive flywheel hybrid systems to 250 buses; partners on international development
November 24, 2014
|Gyrodrive. Click to enlarge.|
Alexander Dennis Limited (ADL), Britain’s biggest bus and coach manufacturer, has chosen GKN Hybrid Power as a preferred partner and committed to the purchase of 250 of its Gyrodrive electric flywheel hybrid systems (earlier post). ADL will focus initially on the introduction of the low emission technology to bus fleets in London and Oxford but anticipates rapid deployment across the UK in the next few years. It will also be working closely with GKN to develop the technology for international markets.
Instead of a battery, the Gyrodrive system uses a magnetically loaded high-speed carbon-fiber flywheel to store the energy generated by a bus as it slows down to stop. It then utilizes the stored energy to power a GKN EVO electric motor which helps accelerate the bus back up to speed, generating significant fuel savings of up to around 25% at a considerably lower cost than battery-hybrid alternatives.

Visio.M partners present new lightweight EV; 13.5 kWh pack delivers ~100 mile range
October 20, 2014
|Visio.M EV. Click to enlarge.|
The academic and industry partners in the Visio.M consortium (earlier post) are showcasing their new lightweight urban electric vehicle at eCarTec in Munich. The 2.5-year project was funded under the priority program “Key Technologies for Electric Mobility - STROM” of the German Federal Ministry for Education and Research (BMBF) with a total budget of €10.8 million (US$13.7 million).
The Visio.M has a range of around 160 kilometers (99 miles) and can accommodate two people with luggage. With only a 15 kW motor, the vehicle reaches a maximum speed of 120 km/h (75 mph). The electric motor in Visio.M draws its power from a lithium-ion battery pack behind the seats, which consists of consumer cells and provides a capacity of 13.5 kWh.
Visio.M researchers develop lightweight torque vectoring transmission for EVs; improved regen, better dynamics
October 15, 2014
|The lightweight torque vectoring transmission is applied in a Visio.M test vehicle. Click to enlarge.|
As part of the Visio.M project in Germany, researchers at the Technische Universität München (TUM), along with their colleagues in the consortium, have developed a lightweight torque vectoring transmission with characteristics that are optimally adapted to electric vehicles. The engineers at the Gear Research Center (FZG) at TUM focused on recouping as much braking energy as possible with the goal of enhancing the range of the vehicle.
Whereas drive torque conventionally is distributed evenly to the wheels of the drive axle, a torque vectoring system allocates torque between the wheels as required, noted FZG engineer Philipp Gwinner. This provides particularly good drive dynamics. As an example, when a vehicle accelerates in a curve, greater torque is applied to the outside wheel. The car steers itself into the curve. The result: greater agility and, at the same time, safer road handling.
EPA annual trends report finds new vehicle fuel economy at record 24.1 mpg; new powertrain technologies rapidly gaining share
October 10, 2014
EPA released the latest edition of its annual report on trends in CO2 emissions, fuel economy and powertrain technology for new personal vehicles in the US. Among the top-level findings was that Model year 2013 vehicles achieved an average of 24.1 mpg (9.76 l/100 km)—a 0.5 mpg increase over the previous year and an increase of nearly 5 mpg since 2004. Fuel economy has now increased in eight of the last nine years; average carbon dioxide emissions are also at a record low of 369 g/mile in model year 2013. The majority of the carbon and oil savings from current vehicles is due to new gasoline vehicle technologies, the report observed.
The report, “Light-Duty Automotive Technology, Carbon Dioxide Emissions, and Fuel Economy Trends: 1975 Through 2014”, also found that the light truck market share increased slightly in MY 2013, after several years of volatility; that the vehicle weight trend is flat and vehicle power trend is increasing more slowly; that many new powertrain technologies are rapidly gaining market share; and that consumers have an increasing number of high fuel economy/low CO2 vehicle choices.
Researchers find isolated Pd atoms efficient low-temperature catalysts to convert CO in automotive exhaust
October 08, 2014
Researchers have found that isolated palladium atoms on γ-alumina supports along with a small amount of lanthanum oxide can efficiently turn the carbon monoxide in automotive exhaust into carbon dioxide at temperatures as low as 40 ˚Celsius, potentially reducing toxins emitted by vehicle exhaust—especially at start-up—and replacing or reducing the need for platinum in automotive catalytic converters.
The catalyst activity can be regenerated by oxidation at 700 °C in air. The high-temperature stability and regenerability of these ionic palladium species make this catalyst system of potential interest for low-temperature exhaust treatment catalysts, the researchers suggested in a recent paper in the journal Nature Communications.

ONR developing offensive autonomous swarming capability for unmanned surface vehicles; adapting JPL’s CARACaS
October 05, 2014
The Office of Naval Research (ONR) is developing an autonomous offensive swarming capability for unmanned surface vehicles (USVs) not only to protect Navy ships, but also, for the first time, to attack hostile vessels.
The technology under development—based on the Control Architecture for Robotic Agent Command and Sensing (CARACaS) developed by NASA’s Jet Propulsion Laboratory (JPL)—can be put into a transportable kit and installed on almost any boat. It allows boats to operate autonomously, without a Sailor physically needing to be at the controls. Capabilities include operating in sync with other unmanned vessels; choosing their own routes; swarming to interdict enemy vessels; and escorting/protecting naval assets.
New “2-in-1” EV unit integrates traction motor and A/C compressor for increased range in hot climates
October 01, 2014
Engineers from Nanyang Technological University (NTU) and the German Aerospace Centre (DLR) have designed a “2-in-1” electric motor unit which can increase the range of electric vehicles in hot climates. This innovative electric machine integrates the A/C compressor, the compressor drive motor and the traction motor into a single housing physically clutching with the compressor during braking events.
The approach unifies the EV traction and compressor drives into a single housing which drive together during braking events. Based on simulations and analysis, the team expects the system to reduce battery consumption by at least 3% compared to existing mechanisms while improving the regenerative energy capturing capacity of the system by 8%. Overall, the novel design could increase the range of electric vehicles by an additional 15 to 20% with other modifications, the researchers suggested.

Honeywell Global Turbo Forecast projects 49M turbocharged vehicle sales, $12B revenue per year by 2019
September 30, 2014
The automotive turbocharging industry will generate $12 billion in revenue by equipping 49 million vehicles with turbochargers annually by 2019, according to Honeywell Turbo Technologies’ 2014 Global Turbo Forecast. The continued growth of turbocharging technologies will be driven by requirements for manufacturers to meet global environmental emissions regulations and bolstered by strong demand in emerging markets.
Automakers are turning to downsized turbocharged engines to satisfy more stringent global fuel economy and emission regulations and customer demand for better-performing vehicles. Turbochargers can help downsized engines improve fuel economy as much as 20 to 40% in gasoline and diesel engines, respectively, when compared with larger naturally aspirated engines and still provide the same or better engine performance. In addition to improving fuel efficiency, downsized turbocharged engines also reduce harmful exhaust emissions.
ORNL team using neutron imaging to study cavitation inside GDI fuel injector
September 22, 2014
Researchers from the Fuels, Engines and Emissions Research Center (FEERC) at the Department of Energy’s Oak Ridge National Laboratory and collaborators from ORNL’s High Flux Isotope Reactor (HFIR) (earlier post) are using neutron imaging to study the formation of damage-causing bubbles in fuel injectors. When gas bubbles form in injectors, they disrupt the spray pattern and ultimately deteriorate the injector material properties.
Under a Laboratory Directed Research and Development (LDRD) project, the team, led by Eric Nafziger, Derek Splitter and Todd Toops from FEERC/ORNL, is attempting to make the first neutron images of cavitation—the physical event that leads to bubble/gas formation—inside the body of a spray-guided gasoline direct-injection (SGDI) unmodified 6-hole injector.
MAHLE NanoNapier Steel piston ring helps reduce weight and improve quality
September 18, 2014
MAHLE has developed a piston ring with new technology that offers engine manufacturers improvements in weight, quality and overall value. MAHLE’s new “second” piston ring uses chrome-silicon steel to replace cast iron traditionally used for the second of three rings found on gasoline-powered spark-ignition engines. MAHLE’s thinner, lighter-weight steel-wire design for the second ring is based on the company’s own NanoNapier Steel (NNS) technology for which a patent is pending.
Conventionally, there are two types of piston rings: compression and oil control. A piston assembly includes one or more compression rings that generate a seal between the outer surface of the piston and the wall of the cylinder to prevent high-pressure combustion gases and air from escaping the combustion chamber. Today’s engines have three piston rings: two compression rings: top (or first) and second and the oil control ring. The second ring is known as a Napier ring.

|The assembled 200W TEG tested in June delivered 270W of output. Click to enlarge.|
GMZ Energy and its partners are on track to deliver a 1 kW thermoelectric generator (TEG) for the Bradley Fighting Vehicle as well as to design and to integrate a light-duty vehicle TEG into a Honda Accord as part of a DOE-funded project. Thermoelectric materials convert temperature differences into electric voltage; a TEG in a vehicle is designed to convert waste heat to power. GMZ Energy, a provider of advanced nano-structured thermoelectric generation technology, was co-founded by MIT’s Professor Gang Chen and collaborator Zhifeng Ren of the University of Houston.
The project is using Half-Heusler (HH) thermoelectric materials (earlier post) in designing the vehicular TEG systems. Although these materials (ferromagnetic intermetallic alloys with a strong crystal structure that allows great stability at high temperatures) have a ZT (dimensionless figure of merit) lower than some other TE materials such as Skutterudites, the mechanical strength and the reliability of HH compensates for this deficit, according to GMZ.
