FIELD: engines and pumps.SUBSTANCE: for cleaning of air accumulator from accumulated foreign matters (engine part wear products, fuel incombustible admixtures, etc.), control system generates the blowdown valve opening signal periodically and at the engine run-up cycle start. Blowdown valve opens to eject air from said accumulator along with impurities. Thereafter control system closes said valve to make it ready for the next operation cycle. Direct blowdown feature consists in air accumulator charging and discharging via air accumulator inlet and ejection in atmosphere is realised via air accumulator outlet.EFFECT: higher reliability.1 dwg |
