Heavy Duty Diesel Engine and Powertrain Development for Japan’s 2009 Exhaust Emission Regulations and the 2015 Heavy Duty Fuel Consumption Regulations

Abstract

This study is Heavy Duty Engine and Powertrain development for new model of Quon. The high pressure of the fuel injection pressure for reducing PM. high-boost and high EGR ratio for reducing NOx, also close air management control can provide a higher torque at a low speed of the engine, and a higher power. As driveline, the gear ratio of transmission was changed to aim for improve the fuel consumption and the drivability. Improve fuel economy performance by the reciprocal driving control technology by engine and transmission.
