FIELD: engines and pumps.
SUBSTANCE: invention relates to two-stroke internal combustion engines with a split cycle. Principle of the invention consists in that the engine has a single or multi-stage pre-cooled compression, which allows the temperature and pressure of the air sucked into the combustion cylinders to be under full control, and due to that a much higher compression ratio and pre-ignition compression pressure can be achieved without approaching the autoignition threshold. Since this design can effectively regulate and set the maximum pre-ignition temperature of the air-fuel mixture, it can work on virtually any type of liquid hydrocarbon fuel without knocking. Due to its higher compression ratio, this "push-pull" motor generates energy equal to or greater than the four-stroke CWPSC engine in a lighter and smaller casing and with equal or greater efficiency.
EFFECT: technical result consists in higher engine efficiency.
