Abstract

Conventional spark-ignited gas engines with a mechanically controlled fuel feed valve have several disadvantages in terms of operation, expensive control, irregular combustion or unstable and unreliable operation, which in turn can lead to operational and mechanical problems. In order to eliminate these disadvantages it is suggested, according to the invention, that a controlled valve is installed in the fuel line upstream of the fuel feed valve so that in the fuel line between fuel feed valve and controlled valve a defined intermediate volume is created and gaseous fuel is fed via the controlled valve into the intermediate volume.
