Summary

Using the crank-offset is state of the art in stationary engines and SI engines, predominantly of Japanese manufacturers. Over the past years more and more diesel engines for passenger cars with crank-offset were introduced into the market. In this article the results of investigations, which were carried out at the Institute of Internal Combustion Engines & Thermodynamics at Graz University of Technology, will be presented. Parts of the investigations were calculation that based on theoretical advisements about crank-offset and comparative experiments which could validate advantages of an engine with crank-offset. The main focus of the research was put on the thermodynamic engine cycle, as there is only few literature on this topic. Beside the results of the calculations and the experimental investigations, the potential of a passenger car diesel engine with crank-offset will be shown and all the effects on design and operation of an engine with crank-offset will be identified. The result of the investigation shows finally, that the advantages of an engine with crank-offset are moderate. So it will be supposed, that future concepts of diesel engines for passenger cars will not spread widely.
