FIELD: engine engineering. SUBSTANCE: system has gas source 7, pressure regulator 5 and 6 of low and high pressure respectively, gas-air mixer with diffuser 3 and throttle gate, and intake manifold 1. Pipe 2 with through dispensing openings 4 arranged opposite to the engine cylinders. The inner diameter of pipe 2 is equal to the diameter of diffuser 3.
