Intake System Design Effect on Turbocharged Inter-cooled Diesel Engine

The paper establishes a calculation model of the 4105ZLQ turbocharged medium-cooled diesel engine in operating process by the simulation software,investigates the influences of the different diameters of the intake pipe and intake lag angles on the diesel engine performances.The results show that:the diesel engine has the big air input when the intake diameter is about 45 mm,and it can put out the greater power;as to the same intake lag angle,volumetric efficiency reaches to maximum when engine speed is about 1 400～1 600 r/min.
