An internal combustion engine includes a compression chamber that is delimited by fixed housing walls and a movable piston mounted therein, and a porous component that fills the combustion chamber, which is separate from the compression chamber. The combustion of fuel and air takes place exclusively within the porous component. The compression chamber is connected to the combustion chamber only via an overflow cross-section designed to allow the transfer of combustion gases created during combustion from the combustion chamber into the compression chamber.

Internal combustion engine

The present application relates to an injector for use in an internal combustion engine designed to work with fuel/emulsion. Two fuel inlet passages, which are connected to a multichannel distributor and used for feeding fuel from a high pressure hose, are linked with a mixing unit surrounding the nozzle needle. Downstream of the multichannel distributor, in the vicinity of the mixing unit, a make-up liquid inlet passage is connected to a second fuel inlet passage through which the make-up liquid, especially water, is fed to produce emulsified fuel. An amount of make-up liquid V, fed during a pause between two injections from the first make-up liquid supply passage to the second fuel inlet passage, is entirely injected during the following injection phase by the high pressure fuel, supplied as a make-up fuel by a shift valve device, into the combustion chamber of the internal combustion engine, so that the second fuel inlet passage and the fuel capacity of the injector are both entirely flushed by the make-up fuel, thereby preventing, during the working breaks of the internal combustion engine, any corrosion by water rests from the emulsion which might remain in the injector.
