Investigation on Thermal Loading of the High Speed Small Air-Cooled Diesel Engines

This paper will summarize the theoretical and experimental achivements in the thermal load studies which have been done, especially determination of the heat exchange boundary conditions, some new methods will be proposed. This made it possible to predict the distributions of the temperature and the heat flux in heated components, when the engine is still in the design stage. Using the aformentional achievements in the thermal load studies, several types of the engines have been designed and developed. Those high speed small air-cooled diesel engines have been successfully applied to the agricultural and industrial multipurpose utilities in the wide area.
