ICCT update finds real-world vehicle fuel economy gap continues to widen in Europe to 40%

The gap between official fuel-economy figures and the real world for new cars in the EU has reached 40 per cent, according to the latest update by the International Council on Clean Transportation (ICCT) to its on-going research into in-use vehicle fuel efficiency and CO2 emissions. (Earlier post.)

Since 2001, the discrepancy between official measurements of vehicle efficiency and actual performance of new cars in everyday driving has more than quadrupled—a discrepancy that now translates into €450 (US$500) per year in extra fuel costs for the average vehicle. The updated study closely follows on revelations that a similar gap in NOx emissions from diesel passenger vehicles was, at least in the case of Volkswagen, deliberately engineered, and as the European Commission prepares to adopt an improved test procedure that would produce more realistic vehicle test results.

Jaguar Land Rover investigating energy-efficient vehicle heating and cooling; Air Bubbles and Air Blankets

September 10, 2015

Because heating, ventilation and air conditioning systems (HVAC) consume substantial amounts of energy—and therefore fuel, or electrical energy stored in the battery of a Battery Electric Vehicle (BEV)—Jaguar Land Rover (JLR) is working on research projects that could significantly reduce the energy consumed when heating and cooling a vehicle.

Rather than continuously heating or cooling a flow of air as it enters the car, Jaguar Land Rover is exploring how a car could heat or cool an “Air Bubble” inside the vehicle once, and then maintain the temperature and quality of this air bubble using innovative new HVAC technologies. These include infra-red reflective (IRR) glass, tailor-made for the solar radiation profile of an individual region or country. The glass would reflect the sun’s rays so less energy is required to cool the inside of the car.

New Tandem Axle Lift function from Volvo Trucks lowers fuel consumption up to 4%

Volvo Trucks has introduced a new function—Tandem Axle Lift—that makes it possible to disengage and raise the second driven axle even while driving. This gives better road grip and up to 4% lower fuel consumption when the truck is driven without a load. The new function is designed for heavy duty transports with loads being carried one way and empty return trips—for example, when hauling timber or in construction and bulk cargo operations.

By replacing the differential in the first driven axle with a dog clutch, the second driven axle can be disengaged and raised; the tires can be lifted 140mm (5.51 inches) off the road surface. The driver thus has access to both the power and capacity of two driven axles (6X4) and also the better maneuverability of a single driven axle (4X2).

Bosch presenting new heat pump EV thermal management system at IAA; up to 25% increase in effective range

September 08, 2015

At IAA next week, automotive supplier Bosch is presenting a new heat-pump-based thermal management system for EVs that it says can enable an increase in effective range of up to 25% without modifications to the battery.

In battery-driven powertrains, heating and cooling can play a significantly greater role than in gasoline or diesel engines, since without a combustion engine, the vehicle does not have a generous supply of heat. If the passenger compartment is heated using a purely electrical system drawing its power from the battery, range can be significantly reduced. As a result, there has been interest in the industry about the use of heat pumps as a lower energy-intensity solution.

ICCT: industry lagging UN fuel efficiency goals for new commercial aircraft by about 12 years; need for a CO2 standard

September 03, 2015

Reductions in the average fuel burn of new commercial aircraft have returned to the long-term average after stagnating from 2000 to 2010. However, according to a new report from the International Council on Clean Transportation (ICCT), manufacturers continue to lag the UN’s fuel efficiency goals for new aircraft; on average, industry is about 12 years behind the 2020 and 2030 aspirational goals established by the International Civil Aviation Organization (ICAO).

The authors of the ICCT report, which updates its 2009 report on the topic (earlier post), do expect to see an accelerating improvement rate in the foreseeable future due to the introduction of new, more efficient aircraft designs such as the a320neo, 737 MaX, and 777X. Despite that, when comparing the ICAO fuel burn technology goals (a 40% improvement in fuel efficiency for new single-aisle (SA) and small twin-aisle (STA) aircraft in 2020 relative to 2000 levels) with fuel burn trend projections, they found the 12-year time lag between the projected fuel burn improvement and the time needed to reach ICAO’s goals.

FEV working on water injection system using exhaust condensate; fuel consumption improvements up to 16% possible

August 26, 2015

FEV is developing a water injection system for internal combustion engines using condensate from exhaust gases, the “Extended Direct Condensate Injection” system. The concept, as reported in a new paper in the International Journal of Engine Research , demonstrates a potential for efficiency increase of 3.3% – 3.8% in the region of the minimum specific fuel consumption on a stoichiometric combustion concept with Miller cycle and cooled external exhaust gas recirculation.

Further improvement of the efficiency of up to 16% is possible at full-load operation, the researchers said. If water injection is used in addition to homogeneous lean combustion, an efficiency gain of 4.5% in the region of the minimum specific fuel consumption is achieved.

Team from GM, Ford, FCA reviews how to calculate engine efficiency benefits of high octane fuels

August 25, 2015

A team of engineers from GM Powertrain, Ford and FCA have published a detailed review of how to estimate the engine efficiency benefits of higher octane fuel—e.g., fuel with higher ethanol content—for part- and full-load operation for different engine types and fuel assumptions. Their paper is published in the ACS journal Environmental Science & Technology.

Engine compression ratio plays a fundamental role in engine efficiency; a higher compression ratio improves efficiency, but also causes higher temperatures and pressures of the unburned air-fuel mixture which can lead to knock at high loads. Compression ratio is thus limited to avoid knock. The compression ratio selected for a particular engine depends, the authors note, on the expected duty cycle and fuel octane. A higher compression ratio can be used if an engine will operate primarily at light loads, such that degraded efficiency at high loads is more than offset by improved efficiency at light loads.

CMU analysis finds BEVs powered with natural gas-based electricity have about 40% of the lifecycle GHGs of a conventional gasoline vehicle

August 21, 2015

According to a new lifecycle analysis by a team at Carnegie Mellon University, a battery electric vehicle (BEV) powered with natural gas-based electricity achieves around an average 40% lifecycle greenhouse gas (GHG) emissions reduction when compared to a conventional gasoline vehicle. Plug-in hybrids (PHEVs), either with a 30- or 60-km range, when powered by natural gas electricity, have the second lowest average emissions. Both BEVs and PHEVs provide large (more than 20%) emissions reductions compared to conventional gasoline, but none of them is a dominant strategy when compared to gasoline hybrid electric vehicles (HEVs), the team found.

Gaseous hydrogen fuel cell electric vehicles (FCEVs) and compressed natural gas (CNG) vehicles have comparable life cycle emissions with conventional gasoline, offering limited reductions with 100-year global warming potential (GWP) yet leading to increases with 20-year GWP. Other liquid fuel pathways using natural gas—methanol, ethanol, and Fischer–Tropsch liquids—have larger GHG emissions than conventional gasoline even when carbon capture and storage technologies are available. The study is published in the ACS journal Energy & Fuels.

New UMTRI report on US vehicle fuel economy from 1923-2013 suggests need to focus on improving lower tails in each vehicle class

August 17, 2015

In a new report, researchers at the University of Michigan Transportation Research Institute (UMTRI) have calculated the actual, on-road fuel economy for the entire fleet of all vehicles in the US, and for different classes of vehicles, with primary interest in light-duty vehicles (cars, pickup trucks, vans, and SUVs), between 1923 and 2013.

The main findings from the analysis are that fuel economy decreased from 14.0 mpg (16.8 l/100 km) in 1923 to 11.9 mpg (19.6 l/100 km) in 1973. Starting in 1974, fuel economy increased rapidly to 16.9 mpg (13.9 l/100 km) in 1991. Thereafter, improvements have been small, with fuel economy in 2013 at 17.6 mpg (13.4 mpg US). Overall, the results suggest, the authors conclude, that efforts on improving fuel economy should focus on the lower tails of the distributions of fuel economy in each vehicle class.

The Chevrolet Volt’s all-new second-generation Voltec extended-range electric propulsion system (earlier post) delivers 53 miles (85 km) of all-electric range, based on EPA testing. That is nearly a 40% improvement over the first-generation Volt, and a 6% boost over the projected 50-mile (80 km) AER estimated at the new Volt’s unveiling in January. (Earlier post.)

Chevrolet expects many next-generation Volt owners will use power solely from their batteries for more than 90% of trips. Today, Volt owners use battery power on 80% of their trips, according to GM. The additional range would enable the average Volt owner to travel well over 1,000 miles (1,609 km) (in multiple trips) between gas fill ups, if they charge regularly.

Researchers find HEV under real-world conditions delivers significantly greater fuel economy benefits than EPA “sticker” values

August 03, 2015

In a new study reported in the ACS journal Environmental Science & Technology, a team at the University of Vermont found that when including real-world road grade and ambient conditions compared to controlled laboratory tests, fuel consumption benefits for a hybrid electric vehicle (HEV) under study increased by 18% highway and 33% city compared to estimates based on EPA adjusted fuel economy “sticker” values. (The vehicles under study were a conventional and hybrid Camry).

In other words, they found that they real-world fuel economy benefit of adoption of HEVs may be better than for estimates based on EPA “sticker” fuel economy alone. The duo, Britt A. Holmén and Karen M. Sentoff, suggested that based on these results, more positive forecasts for future petroleum and corresponding CO2 emissions savings from increased hybridization of the passenger vehicle fleet may be warranted.

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.

GM using Continental Structural Plastics’ TCA Ultra Lite in Corvette for 20 lb weight savings

July 22, 2015

Continental Structural Plastics (CSP), a global provider of lightweight composite solutions, announced that its Tough Class A (TCA) Ultra Lite material, introduced in September 2014, is now in production on the 2016 Chevrolet Corvette. The use of TCA Ultra Lite, a Class A body panel material, results in a 20 lb (9 kg) weight savings on the Stingray Coupe model. This is the first production use of CSP’s Ultra Lite advanced composite.

Ultra Lite technology uses treated glass bubbles to replace some of the CaCO3 (calcium carbonate) filler, allowing the resin to adhere to the matrix and increase the interfacial strength between the bubble and the resin. This is a patented treatment technology that results in a more robust resin mix that makes molded parts more resistant to handling damage, and prevents the micro-cracks that cause paint pops, pits and blistering. The treated bubbles also help with paint adhesion and bonding characteristics.

Ford’s first mass-produced carbon fiber wheels

July 12, 2015

To source the new lightweight track-capable carbon fiber wheels that are standard on the new Shelby GT350R Mustang, Ford partnered with Australia-based Carbon Revolution. Carbon Revolution first began delivering composite wheels in 2004 for Formula SAE campaigns. The company now is producing its “CR-9” wheel series in limited numbers for Porsche, BMW M3, Audi R8, Lamborghini and McLaren MP4-12C within Europe, Japan and North America. Ford, however, wanted more of a mass-production solution.

The one-piece carbon fiber wheels for the Mustang weigh nearly half that of an equivalent aluminum wheel (18 pounds versus 33 pounds), and handling and acceleration performance see serious benefits. The wheels also provide a reduction in rotational inertia of more than 40%, which positively impacts acceleration and braking performance. The wheels are so light, the springs and MagneRide dampers had to be recalibrated because the suspension can respond considerably faster to road inputs.

Study: even with high LDV electrification, low-carbon biofuels will be necessary to meet 80% GHG reduction target; “daunting” policy implications

A study by researchers from the University of Wisconsin-Madison and a Michigan State University colleague has concluded that even with a relatively high rate of electrification of the US light-duty fleet (40% of vehicle miles traveled and 26% by fuel), an 80% reduction in greenhouse gases by 2050 relative to 1990 can only be achieved with significant quantities of low-carbon liquid fuel. The paper is published in the ACS journal Environmental Science & Technology.

For the study, the researchers benchmarked 27 scenarios against a 50% petroleum-reduction target and an 80% GHG-reduction target. They found that with high rates of electrification (40% of miles traveled) the petroleum-reduction benchmark could be satisfied, even with high travel demand growth. The same highly electrified scenarios, however, could not satisfy 80% GHG-reduction targets, even assuming 80% decarbonized electricity and no growth in travel demand.

Tire-integrated triboelectric generator harvests electricity from rolling tire friction; est. up to +10% fuel econ

June 30, 2015

A group of University of Wisconsin-Madison engineers and a collaborator from China have developed a triboelectric nanogenerator (TENG) that harvests energy from a car’s rolling tire friction. An innovative method of reusing energy, the nanogenerator ultimately could provide automobile manufacturers a new way to squeeze greater efficiency out of their vehicles.

The TENG is a novel energy harvesting device to convert mechanical energy into electricity based on the universally known triboelectric principle—i.e., the generation of an electric charge resulting from the contact or rubbing together of two dissimilar objects. Specifically, the nanogenerator relies on the triboelectric effect to harness energy from the changing electric potential between the pavement and a vehicle’s wheels.

Ford assessment of two cylinder deactivation strategies for award-winning 3-cyl. EcoBoost

June 23, 2015

Ford wien1
A comparison of the benefits of two different cylinder deactivation operating strategies for downsized 3-cylinder engines such as the 1.0L EcoBoost. The largest difference proved to be in cost. Schamel et al. Click to enlarge.

Ford’s 1.0-liter EcoBoost engine recently received its eighth award in four years at the 2015 International Engine of the Year Awards. The judges selected the 999cc EcoBoost as the winner (for the fourth consecutive year) in the “Sub 1-Litre” category, awarding it 444 points. The second place challenger, GM’s 999cc EcoTec 3-cylinder turbo, scored 176 points. (Although the EcoBoost received 61 fewer points than last year, the gap between first and second place widened.) Last year, the 1.0‑liter EcoBoost became the first engine to be named overall International Engine of the Year three times in a row, and was in 2012 named “Best New Engine.”

One of the judges, Hormazd Sorabjee of Autocar India said, “That so much can be achieved from a sub 1-liter, three-cylinder motor is simply astounding.” That may be, but Ford is exploring ways to further improve the fuel efficiency of the three-cylinder design, including the possible use of cylinder deactivation.

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.

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.

Behind Audi’s new “rightsized” efficient EA888 Gen.3B family

May 14, 2015

Audi’s new “rightsized” 2.0L Gen.3B engine maintains the displacement of the 2.0L Gen.3 and delivers the power of the 1.8L TFSI with the fuel consumption of the 1.4L TFSI. Click to enlarge.

Audi’s new higher-efficiency series-production 2.0 TFSI turbocharged gasoline direct injection engine introduced at the Vienna Motor Symposium last week is the first of the company’s EA888 Gen.3B family. The engine, featuring a new combustion method based on the Miller cycle, will be used for the first time in the next generation of the A4. (Earlier post.) 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), resulting in a smaller effective compression stroke; combustion and expansion proceed normally.

The new Audi engine combines shorter intake events with a high geometric compression ratio; together with other refinements to the basic engine, the new combustion concept enables a reduction in combined cycle CO2 emissions of up to 10-12 g/km compared to its predecessor.

Japan Ministries propose light commercial vehicle fuel economy standards for 2022

April 28, 2015

In a policy update, the International Council on Clean Transportation (ICCT) reports that Japan’s Ministry of Land, Infrastructure, Transport and Tourism (MLIT) and Ministry of Economy, Trade, and Industry (METI) have finalized new proposed fuel economy standards for light- and medium-duty commercial vehicles with gross vehicle weights less than 3.5 tonnes. MLIT and METI will use the proposal as a basis for revisions to relevant laws and regulations, with a target for completion in spring of 2015.

The new standards will require that the fuel economy of model year 2022 light and medium commercial vehicles sold in Japan average 17.9 km/L (42 mpg US, 5.6 l/100 km) in 2022, compared to 14.2 km/L (33.4 mpg US, 7.0 l/100 km) in 2012. This represents a 26% increase in fuel economy from 2012 values, and a 23% increase from the 2015 standard of 14.5 km/L (34.1 mpg US, 6.9 l/100 km).

Achates Power testing shows transient capabilities of opposed piston engine

April 27, 2015

Initial test results of the transient control and exhaust temperature management capability of Achates Power’s opposed piston (OP) two-stroke diesel engine show that under a typical transient maneuver—25% to 100% load step at low and constant engine speed—the engine can control both NOx and soot with a minimal torque lag. Test results also showed that the air system control flexibility and robust combustion system that Achates Power developed for the OP engine can be used to achieve high exhaust gas temperatures for a diesel engine at idle-like speeds and load, thereby assisting catalyst light-off.

The results follow a paper published earlier this year detailing steady-state testing results that showed the research 4.9L three-cylinder engine was able to achieve 43% brake thermal efficiency at the best point and almost 42% on average over the modes of the SET (Supplemental Emission Test) cycle. The results from this test confirmed the modeling predictions and pointed to a 48% best BTE and 46.6% average over the cycle for a production design of this engine, the Achates team concluded. With the latest paper Achates Power is exploring other critical attributes necessary to deliver a successful engine to the industry.

Carbon Core of next-gen BMW 7 Series helps reduce sedan’s weight by up to 130 kg; remote control parking

April 18, 2015

BMW presented an initial selection of technology highlights for the next generation of the BMW 7 Series model range featuring developments in lightweight design, driving dynamics, comfort, intelligent connectivity and operation.

Due to the BMW EfficientLightweight strategy, the new BMW 7 Series line-up will weigh up to 130 kilograms (287 lbs) less than the outgoing generation of models. At its heart is a body structure with a Carbon Core based on the transfer of technology from the development of the BMW i models. The use of CFRP for structural elements of the passenger cell based on hybrid construction with ultra-high-strength steels—such as the B-pillars—increases both the overall strength and the torsional and bending stiffness of the passenger cell. To this end, the configuration of sheet metal elements can be adjusted as required, allowing for a significant reduction in the weight of the body.

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.

EIA AEO2015 projects elimination of net US energy imports in 2020-2030 timeframe; transportation energy consumption drops

April 14, 2015

The Annual Energy Outlook 2015 (AEO2015) released today by the US Energy Information Administration (EIA) projects that US energy imports and exports will come into balance—a first since the 1950s—because of continued oil and natural gas production growth and slow growth in energy demand.

AEO2015 presents updated projections for US energy markets through 2040 based on six cases (Reference, Low and High Economic Growth, Low and High Oil Price, and High Oil and Gas Resource) that reflect updated scenarios for future crude oil prices. US net energy imports decline and ultimately end in most AEO2015 cases, driven by growth in US energy production—led by crude oil and natural gas—increased use of renewables, and only modest growth in demand.
