The article discusses the development directions of the then internal combustion engines used in automotive vehicles. The regulations in force regarding permissible emission of harmful and toxic compounds force the vehicle manufacturers to systematically reduce their mass and improve the ecological and economic parameters of engines in order to meet stringent requirements. Favorable application parameters are obtained through the use of downsizing strategies and rightsisers in the construction of motors. The article presents both conceptional concepts. The most important features of downsizing and rightsizing engines, their advantages and disadvantages were determined. There is also described the direction of further development of internal combustion engines, which is characterized by the use of both design strategies.
