FIELD: engine engineering. SUBSTANCE: noncombustible fluid is fed from the reservoir to the nozzle. A signal of charge pressure inside the cylinders is generated. A portion of the noncombustible fluid is injected into the cylinders of the engine through the nozzles as fuel burns. As a result, vapor-gas mixture occurs inside the cylinders which is then expanded. In so doing a signal of crankshaft position and the reference signal are generated. The signals of crankshaft position and charge pressure in the cylinders are amplified. The signal of charge pressure in the cylinder is then compared with the reference signal. If the signals are equal or the signal of charge pressure in the cylinder exceeds the reference signal, the slide valve of the dispenser must be open. In so doing, noncombustible fluid is supplied to the cylinders of the engine. When the reference signal begins to exceed the signal of charge pressure inside the cylinder, the comparator generates a signal which is combined with the signal of crankshaft position to generate the control signal to move the slide valve of the dispenser and supply the noncombustible fluid to the reservoir by-passing the nozzle. The vapor-gas mixture is condensed and cooled downstream of the outlet. The condensate is directed to the reservoir. The gas is released to the atmosphere. EFFECT: enhanced reliability. 3 cl, 2 dwg
