The invention relates to internal combustion engines. A mode of operation of the engine consists in that a volume of a fuel-air mix and (or) a volume of air in a chamber of combustion is adjusted by means of change of quantity of exhaust gases, which have stayed in the chamber of combustion. The internal combustion engine comprises a piston (1), a case (2), a device (3) for submission of air, a device (4) for submission of fuel, an exhaust system (5), a system (6) timings gas distribution. Therewith, in the exhaust system (5) there is installed one device (7) for change of pressure or several devices (7) for change of pressure in order to adjust a volume of air in the chamber of combustion by means of change of quantity of exhausted gases , which have stayed in the chamber of combustion. A return valve is mounted in an inlet tract. There are considered variants of engine with a submission of a fuel-air mix or its parts depending on the quantity of the exhausted gases and an adjustment of the exhausted gases by means of change of phases of opening and closing of inlet valves (8) and exhaust valves (9) and (or) by means of change of time and height of their opening. The invention provides with a reduction of fuel consumption in modes of fractional loads and a reduction of repugnant substances in exhaust gases. |
