A Diesel Efficiency-Engine~Cost-Effective Approach for Future Diesel Power Train
Published May 23, 2012 by Society of Automotive Engineers of Japan in Japan
Reduction of fuel consumption and costs dominate the future market requirements in drive train development. An efficiency-engine concept is an approach by reducing specific power density. Compared to downsizing concept, this is cost-effective approach good for world-wide application and electrification. Required peak firing pressure can be similar to those of turbocharged gasoline engines. This enables significant friction reduction of crank train and increases part commonality with gasoline engines. Achievable CO2 reduction is similar to a swept volume reduction by 20 to 25%. The paper discuss about such an efficiency engine concept in comparison to a typical downsizing concept.
