FIELD: mechanical engineering; internal combustion engines. SUBSTANCE: proposed control system has gas exchange hydraulic cutoff mechanisms with control and drain main lines, fuel feed cutoff mechanism, fuel injection pump with drive and working liquid pressure source with delivery main line. Distributing device couples delivery, control and drain main lines. Multiposition engine duty selector with two groups of fixed contacts and with movable contact is connected to power supply source. System has compressed air supply source, shutoff device and air main line. Distributing device is made in form of hollow cylinder with partition forming air and hydraulic spaces accommodating spring-loaded air and hydraulic pistons installed for displacement and interconnected by rod. Channel made in hydraulic piston connects control main line with delivery main line in one extreme position and control main line with drain line in other extreme position. Compressed air source is connected by main air line through shutoff device with air space of distributing device and with fuel feed cutoff mechanism. EFFECT: simplified design. 4 cl, 1 dwg
