At 48 volts, a VTES electric supercharger will transform 7kW of battery power into a highly boosted charge of air for downsizedgasoline and diesel engines. There will be no torque deficit or other tradeoffs from essential engine downsizing and higher gearing, which now dominates the development of internal combustion engines.
When applied to a radically downsized 1.2-liter liter naturally aspirated engine, the downsized engine with electric supercharger reduces the 70-100 km/h (44-63 mph) top gear acceleration time from 18 to 11 seconds. More than 90% of the available torque is delivered in less than a second. Compared with a 1.6-liter
During his presentation at the recent California Air Resources Board (ARB) ZEV Technology Symposium, Tatsuaki Yokoyama, from Toyota Motor Engineering & Manufacturing North America, said that Toyota aimed to reduce the cost of fuel cell vehicles to 1/10 of the current level by design and materials improvement by commercialization in 2015.
Other technologies—such as efficiency improvements in gasoline engines as well as the rollout of hybrid electric power trains—offer more compelling and cost-effective pathways to reducing CO 2 emissions from European passenger cars, the ICCT says. —The ICCT.
Comparison of Fuel Consumption, Fun to Drive and System Cost of the different powertrain concepts. However, the system cost of the Turbohybrid was 150% that of the baseline, while the system cost of the full hybrid was more than 300% that of the baseline. Downsizing a gasoline engine (e.g., Click to enlarge.
The HyBoost project ( earlier post ), a two-year collaborative research program led by Ricardo in partnership with Controlled Power Technologies, the European Advanced Lead Acid Battery Consortium, Ford, Imperial College London, and Valeo, aims to demonstrate a very cost-effective, ultra-efficient gasoline engine in a C-segment passenger car.
For the electric-powered vehicles, the electricity cost is relatively low, reflecting the low cost of electricity and the high efficiency of batteries and motors. The gasoline, on the other hand, is a large expense, especially for the conventional vehicle. Battery replacement had minor overall improvements in cost-effectiveness.

UK car buyers are turning away from diesel in favor of gasoline models, according to new research by Whatcar.com. Intelligence survey results, which indicate that more than seven in 10 would be likely or very likely to choose a gasoline car, compared with the four in 10 who would consider buying a diesel. UK market share respectively.
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. Diesels offer a promising pathway for compliance and another option in manufacturers’ toolboxes. ”.
Using a 2007 base vehicle, the committee estimated the potential fuel savings and costs to consumers of available technology combinations for three types of engines over that timeframe: spark-ignition gasoline, compression-ignition (CI) diesel, and hybrid.
The output power is more than 100kW, despite significant unit downsizing. From the perspective of mobility zones based on travel distance, hybrid and plug-in hybrid vehicles can match the everyday usability of a current gasoline car, and become mainstream environmentally friendly vehicles. Toyota’s view of hydrogen.
The costs of most clean energy technologies fell more rapidly than anticipated. Engine downsizing and weight reduction represent around 30% of that potential collectively. Vehicle downsizing has enabled considerable efficiency improvements, particularly in OECD regions and since 2005.

3 B-Cycle gasoline engine is the first example of Volkswagen’s “Rightsizing” strategy—an engine development strategy that looks to for the optimal balance of displacement, output, torque and efficiency based on vehicle class and real-world operating conditions, rather than just seeking to downsize. Third, the EA888 2.0TSI Gen.3
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. Since it can refuel from a standard household outlet and from a gasoline station, it needs no new infrastructure. It is much more than that. Engineering Advantages of the PHEV.
