Abstract

An internal combustion engine has an electromechanical valve train, in which the valve control device houses not only the output stage for the ignition system and the output stage for the fuel injection system. The valve control device can rapidly prevent the ignition of the air/fuel mixture in the cylinder affected by the valve failure of an electromechanically actuated valve. Moreover, all output stages important for the thermal combustion process are combined in one control device, which is advantageously connected to a water-cooling system.
