FIELD: mechanical engineering; internal combustion engines.
SUBSTANCE: invention can be used in manufacture and operation of engines with injections of fuel-air mixture into engine operating cylinder. Operating cylinder with pistons, pre-combustion chamber with spark plug and combustion chamber are connected with fuel-air mixture charge in form of compressor cylinder with piston. Fuel and air feed channels are arranged in upper part of compressor cylinder higher than its piston top dead center and are furnished with check valves. Channels to feed fuel-air mixture into combustion chamber and pre-combustion chamber are made in form of tube divided along its longitudinal axis or in form of two tubes installed parallel to each other in space with cooling liquid and are furnished with heater. Temperature transmitter is installed in zone of location of said channels and connected with heater supply unit. Channel delivering fuel-air mixture into pre-combustion chamber is furnished with adjusting mechanism with drive connected with crankshaft speed sensor or fuel feed device. Combustion chamber is cylindrical. Projections axes of sections onto channels entering combustion chamber and pre-combustion chamber onto plane of longitudinal section of operating cylinder are square to its axis.
EFFECT: improved stability of operation of internal combustion engine, increased its power output, reduced fuel consumption owing to homogenization of fuel-air mixture.
