At the US Department of Energy’s (DOE’s) Annual Merit Review meeting in Washington, DC last week, Michael Ruth from Cummins noted that the DOE program target for the project is a fuel economy (CAFE) target of 26 mpg (9.05 Earlier post.). l/100 km), and as such would not meet the GHG requirement of 28 mpg (8.4
We believe that inverters will become increasingly important to our economy and environment as solar PV, batteries, and similar power sources continue their rapid growth. For example, GM is leading a DOE funded project for a next-generation inverter targeting improving costs to $3.30/kW
Blending 25-50% of this low-temperature ethanol reformate with ethanol or E85 fuels enables dilute engine operation, resulting in substantial improvements in fuel economy and emissions. High-temperature reformers need to burn a portion of the fuel to maintain their reforming temperatures, thereby generating a fuel-economy penalty.
Conversely, short bursts of power can also be absorbed by the SpeedStart generator to recharge the battery during vehicle decelerations. Small displacement engines offer excellent CO 2 and fuel economy benefits; they have lower parasitic losses and operate more efficiently under part load conditions.
The testing process compares fuel economy performance from the vehicle in its original condition with the performance using XL Hybrids’ charge-sustaining hybrid system. XLH engineers have already designed the next-generation release, in which the battery pack is downsized to 1.5 The company had been targeting a 20% reduction.
The analysis used the Ohio State University EcoCAR, a student prototype PHEV, as the basis for the preliminary fuel economy evaluation. Internal combustion engines have been significantly improving in the past decade, after the adoption of technologies such as Gasoline Direct Injection, mild electrification, downsizing and turbocharging.
To address this request, the NRC formed the Committee on the Assessment of Technologies for Improving Light-Duty Vehicle Fuel Economy. Further, the benefits of some technologies are not completely represented in the tests used to estimate corporate average fuel economy (CAFE).
A multi-cylinder version is practical for a wide variety of vehicles and offers greatest benefit to C and D class passenger cars which can take advantage of the low cost architecture and significantly improved fuel economy and emissions.
An automotive TEG is intended to improve fuel economy by power from waste heat to reduce the electric generator load on the engine. GMZ is targeting a fuel economy improvement of 5%. down-speeding, downsized engine, etc.), W/cm 2 to 6.0 Click to enlarge. Fuel Efficiency Thermoelectrics Vehicle Systems'
The ICCT team—John German and Aaron Isenstadt—concluded that diesels have and will retain two significant advantages over gasoline engines: significantly better fuel economy and cargo hauling and towing ability. Meeting the 2025 standard will require an average improvement in fuel economy of about 4.1% Background.
Manufacturers continue to optimize diesel emission controls, such as DOC, DPF and SCR, in order to promote uniform catalyst coating, improve NO x conversion efficiency, reduce back pressure on the engine, and reduce thermal mass. Better catalysts and urea dosing systems can achieve high NOx conversion during lower temperature operation.
The found that using a GPF did not show any fuel economy and CO 2 emission penalties, while the emissions of total hydrocarbons (THC), carbon monoxide (CO), and nitrogen oxides (NOx) were generally reduced. liter downsized turbocharged centrally-mounted direct injection engine. Yang et al. Click to enlarge.
This downsizing enables lower fuel consumption, accompanied by low emissions and optimum weight. The 4-cylinder Sprinter features a 7-speed automatic transmission with torque converter—the only 7-speed automatic transmission to feature in a van—is refined for maximum fuel economy. Accessory equipment.
On 15 Sep, NHTSA and the US EPA proposed a joint rulemaking on fuel economy and greenhouse gas emissions for light duty vehicles: an average new car 34.1 mpg if the automotive industry were to meet this CO 2 level just through fuel economy improvements.) ( Earlier post.). Turbocharging and downsizing: 26% for cars, 15% for trucks.
The resulting higher BMEP levels allow downsizing of the engine at equivalent vehicle performance. The vehicle owner will realize high fuel economy because gasoline, with its greater eating value per volume, is the fuel that is primarily used for most driving modes. Earlier post.)
Conversion efficiency is now the key. Per the regulations, the Mercedes team downsized their internal combustion engine (ICE) to a 1.6 Friction-reducing oil components, which make it easier for metal surfaces to slide past each other, have also been used to improve overall fuel economy. The F1 W05. Click to enlarge.
Conversion to wider gear ranges. Shift responsiveness has improved through downsizing of the pulley and reduction of inertia by 40%. Both smooth and comfortable launch performance are realized. In line with the adoption of a launch gear, belt use is now specified for higher gear ratios. liter class.
technology and there is progress on the economic conversion of biomass to. Researchers at the US EPA investigating this approach concluded that the M85 and E85 engines could provide efficiencies comparable or higher than the diesel, in dedicated fuel, high compression ratio turbo charged/downsized engines. Earlier post.).
This is because the ethanol component may affect the conversion efficiency of the gasoline component in a blend, that is, make an engine more or less efficient in its use of the gasoline component. converted all vehicle efficiency measurements into vehicle energy efficiency (VEE, km/MJ) based on fuel energy densities reported in each study.
Ford’s turbocharged, gasoline direct injection EcoBoost engines are targeted to play a significant near-term role in Ford’s efforts to reduce fuel consumption by enabling downsizing. V6 engine (the Duratec D35 EcoBoost) delivers up to 12% better fuel economy and 15% lower emissions with comparable torque and power as a 5.4L
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% 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%
Despite its efficiency, the Golf TSI BlueMotion with the 85 kW / 114 hp downsized 999 cc EA211-series engine reaches 100 km/h in 9.7 This offers benefits in terms of internal engine friction, which in turn have a positive effect on fuel economy. seconds and goes on to a top speed of 204 km/h (127 mph). l/100 km. Cooling and heating.
Essential to this is the recognition that current fuels available in the marketplace constrain engine efficiency and limit the potential fuel economy and greenhouse gas improvements available across the light, medium, and heavy duty transportation fleet. We have certainly thrown it out there as something to discuss. —Robert Wagner.
Several after-market companies have done PHEV conversions of the Ford Escape hybrid and one has done a retrofit of the F-150 pickup -- see Where PHEVs Are and ICE-Conversions.) But I can tell you that this is a top priority program for GM, given the huge potential it offers for fuel-economy improvement." ( GM ). Red Herring ).
Thanks to this rightsizing approach, the new engine enjoys the consumption benefits of a downsizing engine in partial load operation, while at higher loads it has the advantages of a large-displacement engine. The result is optimal efficiency and performance characteristics across the entire engine speed range. Stroppiana, A.,
Frank has spent more than 30 years in breakthrough vehicle development, during which he received two world records for vehicle fuel economy, designed nine generations of PHEVs, and was a four-time winner of US DOE Advanced Vehicle Design competitions. The PHEV provides the advantage in all these criteria.
