FIELD: mechanical engineering; internal combustion engines.
SUBSTANCE: invention is aimed at reduction of mechanical stresses in parts in process of operation and provision of possibility of operation of engines on fuels without special antiknock additives. According to proposed method, fuel is directly supplied into engine cylinder, fuel-air mixture is formed and ignited. In process of working stroke of piston, fuel is delivered into cylinder in portions successively in time, two portions minimum, and ignition of portion of fuel-air mixture is synchronized with moment of injection of corresponding portion of fuel.
EFFECT: reduced mechanical stresses in engine parts, possibility of operation on fuels without antiknock additives.
