FIELD: engines and pumps.
SUBSTANCE: two-stroke internal combustion engine includes the cylinder in the wall of which there made is scavenging and discharge openings and piston with fire-resistant insert at the bottom, which is kinematically connected to crankshaft, and injector; according to the invention, and in head of working cylinder there installed is insert from heat-resistant material with low heat conductivity, in which combustion chamber of cylindrical shape is made; ratio of diameter of combustion chamber to its length is within 0.1-0.15; fuel injector is placed in combustion chamber end face, and a gap between cylinder head and piston in position of upper dead point is 0.8-1.0% of the piston travel value.
EFFECT: increasing compression degree and increasing the efficiency.
