FIELD: mechanical engineering.
SUBSTANCE: invention relates to mechanical engineering, in particular to engine building. Schemes of devices for preparing the working mixture with the specified parameters have been developed and schemes for connecting these devices to four-stroke, two-stroke and rotary internal combustion engines have been developed. An electronic control unit, a compressor with adjustable outlet air pressure and a working mixture preparation device containing groups of pre-chambers, preferably with adjustable volumes of cavities, are introduced into the engine. Each group of pre-chambers contains a pre-chamber 10, 11 with a nozzle for a re-enriched fuel-air mixture and a pre-chamber 8, 9 for compressed air. Groups of pre-chambers with prepared components of the working mixture are alternately connected to the combustion chamber of the engine to realize the working stroke. The re-enriched fuel-air mixture is maintained before ignition in a hot pre-chamber 10, 11 and after mixing with hot air, ignition and subsequent time-controlled exposure of the burning mixture in closed pre-chambers, the working stroke is realized. A given amount of the working mixture and a given ratio of air and fuel are obtained by adjusting the volumes of the cavities of the pre-chambers, depending on the given dose of fuel. The specified compression ratio is obtained by adjusting the air pressure at the compressor outlet, followed by its compression and selection into the pre-chambers when the specified pressure norm is reached.
EFFECT: proposed method provides preliminary preparation of the working mixture with the specified parameters, followed by its complete combustion without delay.
