Diesel Combustion and Emission Study by Using of High Boost and High Injection Pressure in a Single Cylinder Engine (Fourth Report) - Effects of Boost Pressure on Friction Losses and Pumping Losses

摘要

The authors have studied the reduction of exhaust emissions by using high boosted single cylinder engine of heavy duty diesel. The boost pressure has been raised up to 5 times high of natural aspirated engine. The increase of boost pressure causes high friction losses, also effects the pumping losses greatly. There are a few reports of frictions about changing boost pressure widely and authors report the result of friction losses in high boost diesel engine.
