Internal combustion engine for gaseous fuels having a combustion chamber () in which gaseous fuel is burned. The gaseous fuel is kept at an operating pressure in a gas tank () and fed to the combustion chamber () via a supply line (). The combustion chamber () is connected to a fresh air line () through which ambient air is fed to the combustion chamber (). The exhaust gas from the combustion chamber () is fed to an exhaust gas catalytic converter () via an exhaust pipe (). A pressure relief line (') with a switchable release valve () branches off from the supply line (), via which gaseous fuel can be discharged from the supply line ().

Internal combustion engine for gaseous fuels

A gas metering valve for an internal combustion engine. The gas metering valve includes a housing in which a gas chamber is formed, which includes an inlet opening and an outlet opening. A movable valve element is situated in the gas chamber, which is movable by an electrical actuator against the force of a return spring and which cooperates with a valve seat for opening and closing the inlet opening. A blocking valve is situated between the valve element and the outlet opening, which opens in the flow direction to the outlet opening and blocks in the opposite flow direction.

A method for regulating a common rail injector, the method including acquiring a signal of a sensor, which signal is proportional to a pressure in a valve space of the common rail injector; evaluating a change in the signal over time in order to detect at least one operating event of the common rail injector; and modifying at least one operating variable of the common rail injector as a function of the at least one operating event, the at least one operating variable being selected from an opening duration, a closing duration, an opening point in time, and a closing point in time of a switching valve of the common rail injector, and from an opening duration, an opening point in time, and a closing point in time of a needle valve of the common rail injector.

A method for predefining a current through a solenoid coil of a solenoid valve, a closing point in time of the solenoid valve being detected with the aid of a sensor, a sensor value being monitored, and, when a premature closing of the solenoid valve is identified based on the monitored sensor value, the current through the solenoid coil of the solenoid valve is increased.
