ABSTRACT:
An air-compressing four-cycle internal combustion engine with direct fuel injection, especially for the drive of motor vehicles, in which a first injection valve is provided for injecting fuel into a combustion space which is so constructed and arranged that good outputs with favorable fuel consumption are attainable; in lieu of the first injection valve, a second injection valve can be selectively operated which is fed with fuel from a second injection pump or from a separate pump plunger and which is so constructed and arranged that low combustion noises are achieved without regard to output and consumption.
