The 2022 FuelEconomy Guide, released by ORNL for the DOE/EPA fueleconomy.gov website, provides up-to-date information on fueleconomy, environmental and safety data, so consumers can choose the most fuel-efficient vehicle that meets their needs. Credit: Andrew Sproles/ORNL, U.S.
The work at UCL’s Department of Mechanical Engineering will be dedicated to spark ignition in gasoline engines, led by Dr. Pavlos Aleiferis. At the University of Oxford’s Department of Engineering Science, Dr. Martin Davy will lead the project on compression ignition in diesel engines. Earlier post.).
An analysis by a team from the University of California, Davis, MIT and Yale suggests that households that buy a fuel-efficient vehicle tend to compensate for that purchase by buying a bigger, more powerful second vehicle. This unintended effect could erode goals of fueleconomy standard policies by up to 60%.
program is paying nearly 10 times the projected price of carbon credits per ton in the best-case scenario, according to an analysis of the implied cost of carbon dioxide reductions under the program by UC Davis transportation economist Christopher Knittel. A gallon of gasoline creates roughly 20 pounds of carbon dioxide when combusted.
Published in The RAND Journal of Economics and funded by the California Air Resources Board, Archsmith collaborated with Kenneth Gillingham of Yale University, Christopher Knittel of MIT, and David Rapson of the UC Davis Department of Economics to examine vehicle purchasing behaviors using California-based data. —James Archsmith.
EDI was co-founded by Professor Andy Frank from UC Davis—a key figure in the development of the PHEV concept and technology—in 2006. EDI’s solution can improve the fueleconomy of a conventional CNG-powered medium-duty truck by more than 40%, the company said.
The project led by Tang-Wei Kuo from General Motors is focused on optimizing multi-hole injectors for spark-ignited direct-injection (SIDI) gasoline engines. Recently, the most popular SIDI gasoline injectors have been multi-hole type. Davis (UC Davis), R.Sankaran (ORNL). Description. Processor hours (Site).
In response, the US Department of Energy (DOE) and the Renewable Fuels Association charged that the study was fundamentally flawed. CRC research programs are managed by five technical committees (Advanced/Vehicle/Fuel/Lubricants, Atmospheric Impacts, Emissions, Performance, and Aviation.). Background. DOE response.
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 fueleconomy and 15% lower emissions with comparable torque and power as a 5.4L
This is not much different from diesel and gasoline which are produced from refining and cleaning crude oil (a process which heavily involves the use of hydrogen). In addition, fuel cell vehicles have zero-CO 2 and zero particulate tailpipe emissions. The investment in infrastructure is not a distant hope or contained to the US alone.
A study by Jonn Axsen and Ken Kurani from the Institute of Transportation Studies, UC Davis, estimates electricity and gasoline use under three recharging scenarios. In this scenario, gasoline use is estimated and aggregated based on the respondents’ anticipated next conventional vehicles and recorded diary days. Plug and play.
and UC-Davis Emeritus and Bruce R. Frank is Professor Emeritus, Mechanical and Aeronautical Engineering at the University of California, Davis, where he established the Institute for Transportation Studies (ITS-Davis), and was director of the US Department of Energy’s National Center of Hybrid Excellence at UC Davis.
Dr. Ken Kurani from the UC Davis Institute of Transportation Studies (ITS) presented results from the latest in a series of electric drive consumer studies seeking to learn from consumers whether or not PHEVs are a good idea. The Most Plausible Early Market consumers value fueleconomy.
A small gasoline engine provides power for the vehicle over longer distances, much like the Toyota Prius. Environmentalists argue that plug-in hybrid technology is the most immediate option to improve fueleconomy and cut greenhouse gas emissions."
The result is an 80+ mile-per-gallon vehicle — with even greater fueleconomy possible utilizing bio-fuels. Such a vehicle could reduce gasoline consumption for the average American by 50 percent to 70 percent and reduce automobile emissions well in excess of emissions that might result from the additional use of power plants.
13, 2006 Andrew Frank, University of California at Davis Mechanical engineering professor and researcher Andrew Frank has spent much of the last 30 years studying electric motors and batteries to make vehicles more fuel-efficient. Because of this, they can get up to 100 miles per gallon of gasoline.
While conventional gasoline-powered vehicles (sometimes called internal combustion engines (ICE)) run on gasoline that emits carbon monoxide and other gases into the environment, EVs burn fewer and cleaner emissions per mile. Department of Energy (DOE) Alternative Fuels Data Center - How Do Hybrid Electric Cars Work?
Scientist have confirmed that unlike gasoline cars, plug-ins will get cleaner as they get older -- because our power grid is getting cleaner. The comparison keeps being raised, though studies are conclusive: The "well-to-wheel" emissions of electric vehicles are lower than those from gasoline internal combustion vehicles.
Company says its focusing on gasoline and hydrogen. USA Today ) 10/25/06 DaimlerChrysler is downright reluctant, even though it has built four test models, commercial-size vans that run on gasoline and electricity. Hybrid Sonata model year 2011, possible PHEV version in 2013. No announced plans. We hope Ford will, and then move ahead!
and UC-Davis Emeritus and Catherine JJ DeMauro. The alternative-fuel car evolved to reduce exhaust emissions and other problems derived from burning fossil fuels. Though the PHEV combines the two types of energy and power, it is not merely a temporary “transition” between gasoline and diesel cars to pure electric cars.
liter EcoBoost engine also features Ford’s first use of a compacted graphite iron cylinder block in a gasoline engine, the same material used in Ford’s 6.7-liter liter EcoBoost engine features the first use of a compacted graphite iron cylinder block in a gasoline engine, the same material used in Ford’s 6.7-liter
Increased charge sustaining fueleconomy. GM projects the Gen 2 Volt will achieve a 30% increase in EV range, an 11% improvement in charge sustaining label fueleconomy, and improved vehicle performance both as an electric vehicle, and in extended range mode. and Davis, R. liter range extender engine. Harpster, M.,
For buyers looking to tow, it passes the Davis Dam SAE J2807 test with 14,000 pounds and a dead battery. Its also worse than the city, highway, and combined EPA fueleconomy ratings for the Ford F-150 Hybrid, which are 22/24/23 mpg. That increases to a total of 690 miles with a full tank of gasoline.
