Many studies have been actively carried out to increase a specific power of medium speed diesel engine through a rise in supercharging pressure. In these studies it is an important subject to increase the reliability through a reduction in thermal load as well as to improve the thermal efficiency for energy-saving.<BR>In this paper a simulation of cycle and performance was combined with that of thermal load. The specific fuel consumption and thermal load of four-stroke medium speed diesel engine were analyzed for the factors of engine cycle and thermal load such as compression process, supercharging process including suction and exhaust systems, conditions of materials, constructions and cooling of combustion chamber wall components, and so on.<BR>As a result, the effects of the engine cycle and performance on the thermal load were clarified. Such conditions of the cycle characteristics, conditions of combustion chamber walls and their cooling that can reduce the thermal load as well as improve the thermal efficiency could be obtained.
