FIELD: motors and pumps.
SUBSTANCE: invention relates to the field of internal combustion engines, more specifically to the field of four-stroke internal combustion engines with pulsed ignition. Four-stroke internal combustion engine has single or multi-stage forecooling, which allows to monitor the inducted into the combustion cylinders air temperature and pressure, so, that the higher compression ratio and pre-ignition pressure can be achieved without approaching the air-fuel mixture self-ignition threshold. Compressed by the compressor air minimum threshold pressure is 1.8 bar at sea level and the minimum temperature drop is not less than 50 °C in the heat exchanger air cooling radiator. Since this design can effectively adjust and set the fuel/air mixture maximum pre-ignition temperature, it can burn almost any type of liquid hydrocarbon fuel without pinking.
EFFECT: due to its higher compression ratio, this four-stroke engine generates energy equal to or greater than the standard four-stroke engine, in the lighter and smaller body and with higher efficiency.
