摘要： A pre-chamber system for an internal combustion engine, in particular for a gas engine, includes a pre-chamber volume in which an ignitable fuel-air mixture can be fired by an ignition device which can be arranged at the pre-chamber system. The pre-chamber system has a flow transfer passage by which the pre-chamber volume can be connected to a main combustion chamber of the internal combustion engine. The pre-chamber volume includes an ignition region and a flow transfer region which is at least portion-wise delimited from the ignition region by an intermediate wall. The fuel-air mixture can be fired in the ignition region, and the flow transfer passage opens into the flow transfer region and there is provided an air feed passage. Preferably compressed air can be fed to the flow transfer region by way of the air feed passage.

摘要： A method for operating a compression ignition engine includes forming a combustible mixture by mixing generally homogeneously a first fuel and air and introducing this mixture into the at least one cylinder, compressing the combustible mixture with the piston in a compression stroke, injecting a second fuel to the combustible mixture at an injection-time of the second fuel during the compression stroke but before start of combustion, and continuing the compression stroke until combustion starts at those locations in the at least one cylinder where concentration of the second fuel is highest and/or the temperature of the mixture is the highest. Emission of the cylinder and/or mechanical stress of the cylinder caused by the combustion are monitored, and if emissions and/or mechanical stress are above respective predetermined thresholds, individually for the cylinder, the amount and/or the timing of the second fuel injected, and/or temperature of the cylinder charge is changed.
