FIELD: machine building.SUBSTANCE: air compressor 5 sucks air from atmosphere and delivers it into air accumulator 12 wherefrom compressed air is forced via pipeline 16 and control valve 10 to exhaust ejector 6 and, via control valve 7, to supercharge injector 2. The latter creates overpressure in intake manifold 1. Intake manifold pressure is controlled by head transducer 13 and control valve 7. Exhaust ejector 6 creates rarefaction in exhaust manifold 9, rarefaction level being controlled by head transducer and valve 10. Pressure in air accumulator 12 is controlled by pressure gage 15 and valve at compressor inlet 8. Parameters of pickups and valve operation are controlled by control unit of forced gas exchange system 20.EFFECT: higher ICE efficiency, reduced harmful emissions.6 cl, 1 dwg |
