Continental puts first 48V hybrid assist system into production with Renault diesels
October 21, 2016
From the end of 2016, diesel variants of the Renault Scénic and Grand Scénic models will be equipped with Continental’s 48-volt hybrid drive—the first application of the 48V “Hybrid Assist” in production vehicles.
The first production solution combines an efficient, water-cooled induction motor with an integrated inverter. The electric motor transmits power via a belt drive directly to the crankshaft of the combustion engine—an arrangement referred to as “P0 topology.” Further production ramp-ups are soon to be set in motion on the basis of a modular system for 48-volt drives.
2017 Audi Q7 now available with 2.0-liter TFSI turbo-charged four-cylinder engine; lower entry point to premium SUV
October 20, 2016
Audi of America is offering a new 2.0-liter TFSI four-cylinder engine on 2017 Audi Q7 models. This new model, when equipped with the 2.0-liter engine, is half a second faster on the 0-60 mph sprint; nearly 500 pounds lighter; and up to 22% more fuel-efficient than the previous generation Q7 3.0T V6.
With the 2.0 TFSI, Audi is creating a value proposition that makes entry into the luxury full-size SUV more accessible. The starting MSRP ($49,000) (Premium trim) is $5,800 below the current entry point of $54,800 for the Premium 3.0 TFSI; pricing for the 2.0L Premium Plus trim starts at $53,000 ($1,800 below the current entry point and $5,800 below the Premium Plus 3.0 TFSI). The specifications of the 2.0- and 3.0-liter engined cars are virtually the same except for the engine; the inlays which are a mix of aluminum and wood on the lower and upper dash vs all wood; and 18-inch wheels instead of 19-inch wheels.
Daimler Buses to offer electrohydraulic power steering to reduce fuel consumption
October 19, 2016
Daimler Buses will offer electrohydraulic power steering (EHPS) to reduce fuel consumption in coming bus models. The fully integrated system replaces the conventional power steering pumps used currently in all buses with a gross weight of more than 7.5 t.
Conventional hydraulic power steering (HPS) is driven directly by the internal combustion engine via belts or gear trains with a fixed gear ratio which results in a pump speed that is directly proportional to the engine speed. To provide sufficient power for the steering in every situation, the pump must be able to deliver the full volumetric flow rate even when the engine speed is low—meaning that it is over-dimensioned for most operating situations. For this reason, higher engine speeds require a restriction of the volumetric flow rate by means of a bypass, which, however, entails unnecessary losses.
NASA to test in-flight folding spanwise adaptive wing (SAW) to enhance aircraft efficiency; advanced actuators
October 18, 2016
NASA is developing and validating a system that will allow part of an aircraft’s wing to fold in flight to increase efficiency through wing adaptation.
Engineers at NASA’s Armstrong Flight Research Center in California, Langley Research Center in Virginia, and Glenn Research Center in Ohio, are working on the Spanwise Adaptive Wing concept, or SAW. The concept would permit the outboard portions of the wings to move to the optimal position during operation. This could increase efficiency by reducing drag and increasing lift and performance.

The protocol, which is valid for Europe, is carried out in three stages:
Testing confirms Torotrak V-Charge variable drive mechanical supercharger enables more ambitious downsizing; 1.0L demo at Aachen
October 10, 2016
Independent on-engine test results have verified the simulation predictions that a Torotrak V-Charge variable drive mechanical supercharger enables more ambitious levels of engine downsizing. Compared to a current 1.5L GTDI engine producing 240 N·m torque, a 1.0L GTDI engine of the same Ford EcoBoost family outperformed the 1.5L version when fitted with a V-Charge unit.
The tests were carried out by the University of Bath Powertrain and Vehicle Research Centre (PVRC), using a Ford 1.0L EcoBoost engine, in a part-government funded program. The 1.0L engine with V-Charge delivered 250 N·m (184 lb-ft) torque, corresponding to a BMEP (Brake Mean Effective Pressure) of 31 bar.

Infiniti unveils I4 Variable Compression Turbo engine; targeting 27% improvement in fuel efficiency over V6 engines of similar output
September 30, 2016
At the Paris Motor Show, Infiniti unveiled the new VC-Turbo (Variable Compression Turbo)—the first production-ready variable compression ratio engine. (Earlier post.) VC-Turbo technology combines the power of a high-performance 2.0-liter turbo gasoline engine with the torque and efficiency of an advanced diesel powertrain without the equivalent emissions.
Transforming on demand, Infiniti’s VC-Turbo technology uses an advanced multi-link system to raise or to lower the reach of the pistons, detecting the car’s driving condition and driver inputs, and instantly selecting the most suitable compression ratio. The engine is able to offer any compression ratio between 8:1 (for high performance) and 14:1 (for high efficiency).
New ICCT study identifies significant potential to reduce aviation fuel consumption by up to 40% by 2034
September 27, 2016
A new report from the International Council on Clean Transportation (ICCT) identifies significant potential to reduce aviation emissions through emerging fuel efficiency technologies.
The study summarizes the results of the first independent, bottom-up cost assessment of near- (2024) and mid-term (2034) technologies to improve new aircraft fuel efficiency. Carried out in cooperation with a panel of top technical experts and consultants using NASA and DoD-approved models to evaluate aviation technology programs, the study concludes that the rate of fuel efficiency improvement for new aircraft can be more than doubled through 2034, from about 1% today to 2.2% annually, by the adoption of cost effective technologies to improve engine efficiency, reduce aerodynamic drag, and trim aircraft empty weight.

The new Equinox is the first Chevrolet model in North America to use an all-turbocharged, multi-engine powertrain lineup. The 2018 Equinox goes on sale in the first quarter of 2017 in North America and rolls out to approximately 115 additional global markets later in the year.
DEKRA-certified tests: Mercedes-Benz HD trucks cut fuel consumption 22% in 20 years while meeting more stringent emissions rules; VECTO
September 22, 2016
Despite drastically more stringent emission standards for nitrogen oxides and particulates, the fuel consumption of Mercedes-Benz heavy trucks has been reduced by 22% over the last 20 years, according to the results of a comparative test drive certified by the test organization DEKRA.
The August 2016 testing by commercial vehicle magazine Lastauto Omnibus (LaO) compared the latest generation of the Mercedes-Benz Actros long-distance truck compared to the basic model of 1996—a Mercedes-Benz from the SK model series and therefore one of the last representatives of the pre-Actros era. The model 1844 was certified according to the Euro II standard valid in 1996, and was therefore allowed to emit 7 grams of NOx per kilowatt hour (kWh) while staying within the limiting value of 0.15 g/kWh for particulate matter. The number and size of the soot and other particles was not prescribed.

Under development since 2012, the development program for the breakthrough transmission led Kia to patent 143 new technologies to ensure a high level of performance and efficiency in a compact structure.
Study finds isopropanol-n-butanol-ethanol and gasoline blend viable as alternative fuel
September 05, 2016
Researchers from the University of Illinois and colleagues in China investigating the performance, combustion and emission characteristics of a port fuel-injection SI engine fueled with isopropanol-n-butanol-ethanol (IBE)-gasoline blends have concluded that an IBE30 blend could be a good alternative to gasoline.
Bio-n-butanol itself is a promising alternative fuel, produced conventionally from the fermentation of carbohydrates by Clostridium bacteria in a well-established process referred to as ABE fermentation, after its major chemical products: acetone, butanol and ethanol. However, ABE fermentation production suffers from relatively low production efficiency as well as the high cost of component recovery; the product mixture typically has an A:B:E ratio of 3:6:1.

The XL3 hybrid system is available on the Reach van with 2,500 pounds payload capacity with the XL3 system installed. (Hybrid system weight is 385 lbs / 175 kg.)
Select truck fleets boosted fuel economy 3% in 2015 compared to national Class 8 average
August 28, 2016
Seventeen trucking fleets operating more than 62,000 tractors and 217,000 trailers recorded a 3% increase in fuel economy in 2015, saving an accumulative $501 million on fuel when compared to the 2015 national average fuel spend of 1.7 million over-the-road class 8 trucks. They achieved these gains by purchasing a variety of fuel efficiency technologies, according to the Annual Fleet Fuel Study released by the North American Council for Freight Efficiency (NACFE).
As a result of these investments, fleet-wide mpg increased from 6.87 to 7.06 in 2015, the largest margin of improvement in eight years of consecutive improvements. The trade cycle for these fleets is a little over five years, meaning that the new trucks are about 16% more efficient than the 2010 model year trucks they replaced.
USDOT proposes speed limiters for large commercial vehicles; potential savings up to ~$1B in fuel each year depending on limit
August 26, 2016
The US Department of Transportation’s (DOT’s) National Highway Traffic Safety Administration (NHTSA) and Federal Motor Carrier Safety Administration (FMCSA) are proposing equipping heavy-duty vehicles with devices that limit their speeds on US roadways, and requiring those devices be set to a maximum speed, a safety measure that could save lives and more than $1 billion in fuel costs each year.
Specifically, NHTSA is proposing to establish a new Federal motor vehicle safety standard (FMVSS) requiring that each new multipurpose passenger vehicle, truck, bus and school bus with a gross vehicle weight rating (GVWR) of more than 11,793.4 kilograms (26,000 pounds) be equipped with a speed limiting device.
2017 Audi A4 ultra with Millerized 2.0 TFSI offers 31 mpg combined; highest EPA-estimated fuel economy in competitive segment
August 17, 2016
Audi’s 2017 A4 ultra leverages the Millerized 2.0-liter TFSI engine (earlier post) to achieve 27 mpg (8.7 l/100 km) city, 37 mpg (6.35 l/100 km) highway, and 31 mpg (7.58 l/100 km) combined EPA-estimated fuel economy. No other luxury sedan in its non-hybrid competitive segment offers higher EPA-estimated city or highway mileage.
The efficiency of the 2.0 TFSI is the result of Audi’s Millerized combustion method with shorter compression and longer expansion phases as well as increased compression. The Miller cycle uses a higher expansion ratio than compression ratio (i.e., over-expansion) obtained by either early or late closing of the intake valves (EIVC and LIVC, respectively), and results in a smaller effective compression stroke; combustion and expansion proceed normally.
DOE to award up to $137M for SuperTruck II, Vehicle Technology Office programs
August 16, 2016
The US Department of Energy (DOE) will invest up to $137 million in two programs, subject to appropriations, to develop next-generation technologies that will support industry in going beyond the newly announced Phase II standard for medium- and heavy-duty vehicles (earlier post) and also accelerating technology advances for passenger cars and light trucks.
One initiative, SuperTruck II (earlier post), will award $80 million to four projects to develop and to demonstrate cost-effective technologies that more than double the freight efficiency of Class 8 trucks. Through the other initiative, the Office of Energy Efficiency and Renewable Energy Vehicle Technologies Office Program Wide Funding Opportunity Announcement (earlier post)selections, 35 new projects will receive $57 million to develop and deploy a wide array of cutting-edge vehicle technologies, including advanced batteries and electric drive systems, to reduce carbon emissions and petroleum consumption in passenger cars and light trucks.
EPA and DOT issue final Phase 2 GHG and fuel efficiency rulemaking for medium- and heavy-duty trucks
The US Environmental Protection Agency (EPA) and the US Department of Transportation’s National Highway Traffic Safety Administration (NHTSA) jointly released the finalized Phase 2 greenhouse gas and fuel efficiency standards for medium- and heavy-duty trucks.
The product of four years of testing and research and outreach to industry, environmental organizations, labor unions, and other stakeholders, the vehicle and engine performance standards will cover model years 2021-2027, and apply to semi-trucks, large pickup trucks and vans, and all types and sizes of buses and work trucks. These standards will result in significant GHG emissions reductions and fuel efficiency improvements across all of these vehicle types. For example, when the standards are fully phased in, tractors in a tractor-trailer will achieve up to 25% lower CO2 emissions and fuel consumption than an equivalent tractor in 2018.
Infiniti introducing production-ready variable compression ratio engine at Paris Motor Show
August 15, 2016
Infiniti will introduce a production-ready variable compression ratio engine VC-T (Variable Compression-Turbocharged) at the 2016 Paris Motor Show (Mondial de l’Automobile) in September. Infiniti said that the new four-cylinder turbocharged gasoline VC-T engine has been in development for more than 20 years. (Nissan was awarded a patent in 1995 on compression ratio control for an engine.)
Interest in variable compression engines stretches back more than 40 years. In a 1976 SAE paper, Grundy et al. described the Teledyne Continental Motors (TCM) AVCR 1360-2 variable compression ratio (VCR) diesel engine, the culmination of fifteen years of VCR piston and high specific output research. Two main types of variable compression ratio systems have been proposed over the years: continuous and two-stage.

Argonne team discovers self-regenerating DLC tribofilm
August 05, 2016
Researchers at Argonne National Laboratory have discovered an ultra-durable, self-lubricating tribofilm that regenerates in the presence of oil, heat, and pressure—meaning that it will not wear away over the life of an engine. The film, reported yesterday in the journal Nature, develops when a new catalytic coating that can be applied to engine parts interacts with lubricating oil to create an extremely tough coating that almost eliminates wear.
Tests revealed the diamond-like carbon (DLC) tribofilm reduced friction by 25-40% and that wear was reduced to unmeasurable values. The discovery could have implications for the efficiency and durability of future engines and other moving metal parts that can be made to develop self-healing DLC tribofilms.
Survey: Fuel efficiency top criterion for US buyers regardless of size of vehicle; good news for start-stop
August 03, 2016
American consumers are strongly influenced by fuel efficiency and the price of gas when purchasing a vehicle, according to a new survey conducted by the Opinion Research Corporation on behalf of Johnson Controls. Of the 1,006 people surveyed, fuel efficiency (57%) is top of mind for consumers when they go to buy any size automobile, followed closely by cost (55%) and safety (54%).
That preference is consistent with a similar survey conducted five years ago, despite falling gas prices, which are down more than 37% from the national average in 2011. The new survey also found consumers are sensitive to the price of fuel when considering a new vehicle, with 64% saying it directly impacts their purchase. This is up 14% from 2011.

DOE to award $7M to accelerate fuel and engine co-optimization technologies; Co-Optima initiative
August 01, 2016
The US Department of Energy (DOE) will award up to $7 million in project funding to accelerate the introduction of affordable, scalable, and sustainable high-performance fuels for use in high-efficiency, low-emission engines as part of the Co-Optimization of Fuels and Engines (Co-Optima) initiative. (Earlier post.)
Co-optimized fuels and engines offer the opportunity to build on decades of advancements in both fuels and engines. Groundbreaking research in the last 10 years has identified combustion engine strategies that—especially if optimized to run on new fuels—would offer significantly higher efficiency and produce fewer engine-out pollutants than current engines. The new funding opportunity (DE-FOA-0001461) will advance the long-term objective of the Co-Optima initiative to accelerate widespread deployment of significantly improved fuels and vehicles (from passenger to light truck to heavy-duty commercial vehicles) by 2030.
TÜM study finds reduction in fuel consumption from eco-driving training, even with incentives, to be fleeting
A study of the persistence of effects of eco-driving training by a team from Technische Universität München has found that, while there is an immediate reduction of the average fuel consumption following eco-driving training along with the provision of an incentive, there is an attenuation of this effect after six months.
Further, they also found no impact on fuel consumption from purely theoretical eco-driving training—i.e., without incentives—either short-term or long-term. A paper describing their study is published in the journal Energy Policy.

BMW introducing new quad-turbo 6-cylinder diesel in 7 Series; engine output up 5%, average fuel consumption down 11%
May 17, 2016
BMW is introducing its new quad-turbo, six-cylinder diesel, described several weeks ago at the Vienna Motor Symposium, in the BMW 750d xDrive and BMW 750Ld xDrive. The new diesel—billed by BMW as the world’s most powerful six cylinder diesel, generates maximum output of 294 kW/400 hp and peak torque of 760 N·m (560 lb-ft).
The 14 kW/19 hp (i.e. 5%) increase in output and peak torque up by 20 N·m (15 lb-ft) are accompanied by a 11% reduction in average fuel consumption and emissions over the predecessor model. Combined cycle fuel consumption is 5.9 – 5.7 l/100 km (39.8 – 41.2 mpg US); the corresponding CO2 emissions are 154 – 149 g/km. The engine comes standard with intelligent all-wheel drive.
New GM 10-speed auto for Camaro ZL1 shifts quicker than DCT; to be applied in 8 other models by 2018
May 12, 2016
With faster upshifts than a dual-clutch transmission (DCT) and a wider overall gear ratio spread to optimize performance and efficiency, the all-new available GM Hydra-Matic 10-speed automatic transmission sets a new performance standard in the 2017 Camaro ZL1. The transmission is an all-new design—and the first application in a car—with a wider, 7.39 overall gear ratio spread, that enables the ZL1’s supercharged engine to remain at optimal engine speeds during upshifts. GM and Ford began joint development of 9- and 10-speed transmission designs in 2013. (Earlier post.)
The wider overall ratio enables a lower numerical top gear ratio—an attribute that reduces engine speed on the highway, which contributes to greater fuel efficiency than a comparable eight-speed transmission. Improvements in spin loss complement the optimized gearing, further enhancing efficiency. Although the Camaro ZL1 will be the first GM vehicle to offer the new 10-speed automatic, designed for rear-wheel-drive applications, it will be available in eight additional vehicles by 2018.

Tsinghua team evaluates impact of types and arrangements of electric traction motors in fuel cell hybrid buses
April 20, 2016
Researchers at Tsinghua University have compared the performance of two different powertrains for fuel cell hybrid buses. Both buses use 50 kW PEM fuel cell stacks (from different manufacturers) as the primary power source, with LiMn2O4 battery packs as secondary power sources. A significant difference between the two powertrains lies in the types and arrangements of the electrical motor.
One powertrain employs a single induction motor (IM) to drive the vehicle via a reduction gearbox and differential (Powertrain A), while the other powertrain adopts two permanent magnetic synchronous motors (PMSMs) for near-wheel propulsion (Powertrain B). A further difference between the proposed powertrains is the supply path for the fuel cell accessories. A paper on their study is published in Journal of Power Sources.

Since 2013, the share of premium gasoline in total motor gasoline sales in the US has steadily increased to 11.3% in August and September 2015—the highest share in more than a decade, according to data from the US Energy Information Administration (EIA).
This trend of increasing demand for higher octane gasoline is likely driven by changes in fuel requirements for light-duty vehicles (LDV) in response to increasing fuel economy standards, which will have widespread implications for future gasoline markets, according to EIA analysts.
New Renesas 32-Bit MCUs for improved fuel efficiency in vehicle powertrain control applications
April 05, 2016
Renesas Electronics Corporation announced the 32-bit RH850/E1M-S2 microcontrollers (MCUs) for automotive powertrain control applications. The new MCUs provide high performance and advanced functionality to enable improved fuel efficiency. The RH850/E1M-S2 MCUs include four product versions, including the high-end R7F701216EABA (BGA304, 320MHz).
To help meet increasingly stringent fuel efficiency and CO2targets, engine control systems must optimize the ignition and fuel injection timing to match a variety of conditions, such as current combustion and driving status. Transmission control systems, for their part, must instantly select the optimal gear ratio to match the driving conditions, which change moment by moment, in order to minimize power loss in the transmission.

New Federal-Mogul Powertrain piston skirt coatings increase durability for the life of pistons
March 30, 2016
Federal-Mogul Powertrain has introduced two innovative piston skirt coatings: EcoTough-New Generation (for gasoline engines) and EcoTough-D (for diesel engines). Building on the proven performance of previous EcoTough coatings, the new formulations further reduce engine friction, wear and noise while dealing with the increasingly challenging loads and temperatures that exist in the latest downsized, turbocharged engines.
Gasoline and diesel engines require alternative solutions because of important differences in their relative combustion loads, piston geometry and the lubricity of their respective fuels. Federal-Mogul Powertrain has accommodated these differences by formulating specific coatings, each optimized for either gasoline or diesel application.

IIT team explores combustion, performance and emissions characteristics of HCNG blends in spark ignition engine
March 28, 2016
A new study by a team from the Engine Research Laboratory at the Indian Institute of Technology Kanpur explores the combustion, performance and emission characteristics of a prototype spark ignition engine operating with different blend ratios of HCNG (hydrogen and compressed natural gas blends). Their paper is published in the journal Fuel.
Use of lower carbon natural gas and carbon-free hydrogen have potential to reduce harmful emissions of criteria pollutants and greenhouse gas (GHG) emissions and and could displace a portion of conventional liquid fossil fuels, the IIT noted. However, both fuels pose different challenges for use in internal combustion (IC) engines.
CMU study shows autonomous vehicle algorithms can have considerable effect on fuel economy; need for new approaches in testing
March 24, 2016
Autonomous vehicle driving behavior can have a considerable effect on fuel economy. Researchers in the College of Engineering at Carnegie Mellon University have determined that fuel efficiency for self-driving cars—within the bounds of current fuel economy testing—could improve by up to 10% under efficiency-focused control strategies when following another vehicle.
However, the study also showed that autonomous vehicle (AV) technology following algorithms designed without considering efficiency can degrade fuel economy by up to 3%. In a paper published in the journal Transportation Research Part C: Emerging Technologies, Assistant Professor of Civil & Environmental Engineering Constantine Samaras and Ph.D. student Avi Chaim Mersky suggest the need for a new near-term approach in fuel economy testing to account for connected and autonomous vehicles.

MIT Energy Initiative report on transforming the US transportation system by 2050 to address climate challenges
March 16, 2016
A new MIT Energy Initiative report spearheaded by John Heywood, Sun Jae Professor of Mechanical Engineering Emeritus at MIT, identifies three important paths forward reducing light-duty vehicle energy use and greenhouse gas emissions: improve the existing system and technologies for shorter-term benefits; conserve fuel by changing driver habits for nearer- to longer-term benefits; and transform the transportation system into one that is radically less carbon-intensive for longer-term benefits.
According to the report, “On the Road Toward 2050: Potential for Substantial Reductions in Light-Duty Vehicle Energy Use and Greenhouse Gas Emissions,” each element is separately important, but must collectively be pursued aggressively to achieve necessary emissions reductions. More research, development, and demonstration studies are needed to lay the foundation for such a long-term transformation.
