Construction Specialties of Regenerative Piston Internal Combustion Engines

Abstract

Some new results of the theoretical work with the heat regeneration within the internal combustion piston engines are presented in this paper. A new construction of such an engine including better balancing of mass forces is proposed as well. The construction of its process unit makes possible the prolonged expansion alone and together with the heat regeneration which in turn result in better efficiency of processes comparable with those in the conventional internal combustion engines. The regeneration piston internal combustion engine was proposed. A new construction of such an engine is introduced and discussed here. Its relatively sophisticated construction is not very convenient, however fuel economy as well as the fuel insensibility and the lower noise emission are some of the expected advantages of the engine. More realistic predictions of the engine fuel economy were obtained with better simulation of the combustion process. However, majority of the assumptions were based on relatively simple models that could be improved in the future and verified on an real engine prototype.
