FIELD: engine engineering. ^ SUBSTANCE: internal combustion engine comprises reciprocating piston mounted in the chamber of the cylinder provided with the exhaust port in the vicinity to the top dead center and fuel tank provided with fuel and above-fuel spaces. The first space is in communication with the device for preparing combustible mixture through a pipe line, and second space is provided with the passage for supplying high pressure whose inlet port is connected with the working chamber of the cylinder. The second port of the passage is positioned in the zone adjacent to the bottom dead center of the piston, and the top edge of the inlet port and the top edge of the exhaust port are placed in the same transverse plane. The fuel tank receives a flexible diaphragm that separates the fuel and above-fuel spaces of the tank. The sides of the flexible diaphragm are corrugated, and the diaphragm is provided with the flat bearing plate. The top section of the diaphragm is connected to the top wall of the fuel tank. The flat bearing plate is made in block with the power piston mounted in the cylinder secured to the top wall of the fuel tank and connected with the inlet port and working chamber of the cylinder through the passage of supply of high pressure via the receiver-cooler of exhaust gases that comprises stop valve with return spring and cooling fin. The passage for supplying high pressure receives the regulator of fuel pressure in the fuel tank. The regulator has housing, slide valve with radial openings, and return spring of the slide valve. The cylinder space under the slide valve is connected with the fuel space of the fuel tank through the pipeline. The receiver-cooler receives the pressure-reducing valve connected with the exhaust system through the pipeline. ^ EFFECT: enhanced reliability. ^ 1 dwg
