FIELD: mechanical engineering; internal combustion engines.
SUBSTANCE: invention relates to gasoline internal combustion engines operating at higher compression ratio. Proposed engine is furnished with vacuum pump with drive and additional drive of throttle valve, both controlled by electronic control unit. Input of vacuum pump communicates with intake manifold of engine for sucking out air. When engine for sucking out air. When engine shaft is being cranked, no fuel is delivered into cylinder, and after starting of engine, vacuum pump is switched off.
