The present invention relates to a method and a control unit for avoiding condensation of humidity in an intake system of an internal combustion engine after engine switch off. Condensed liquid in the intake system of the stopped engine can lead to icing, corrosion and a hydrostatic lock at the next engine start. To prevent such an engine damage, it is necessary to determine if and in which amount condensed liquid occurs in the cooled intake system and to initiate appropriate actions to eliminate the liquid therefrom. The present invention predicts the occurrence of condensation in the intake system of the cooled engine and initiates corrective measures at engine switch off and during the cooling down period.

The invention relates to an engine having prechamber ignition, in particular a gas engine, that comprises a main combustion space in a cylinder of the engine for combusting an air-fuel mixture and a prechamber having an ignition device arranged therein and a fuel injector arranged therein, wherein the prechamber has at least one transfer port that fluidically connects the prechamber to the main combustion space. The engine is characterized in that the fuel injector arranged in the prechamber is the only fuel injector via which fuel can be introduced into the associated main combustion space.

The present subject matter provides a device and a method for injecting non-combustible fluid into an internal combustion. In order to reduce the non-combustible fluid consumption, the fluid to be injected is heated to a predefined temperature which improves the spray characteristics, reduces wall wetting and leads to a better vaporization of the fluid in the combustion chamber.

The present invention provides a method for avoiding knocking in an internal combustions engine, preferably in a gasoline engine with a high compression ratio and a variable valve train which is able to perform EIVC, by injecting a non-combustible fluid into the intake port and/or in the cylinder during a transient operating mode.
