Abstract
An efficient and economical method to increase the performance of four stroke engines can be supercharging by compressing the intake air with the help of the bottom side of the piston. This publication describes parts of a research project with the target to develop a supercharged four stroke engine with a closed loop lubrication system for the crank train also including the lubrication system for the cylinder head. With the help of a thermodynamic engine analysis, the influence of the crankcase pump on the engine performance behavior and the distribution of losses has been researched and discussed, with the supercharged engine being compared to different naturally aspirated competitors.
