摘要： An internal combustion engine, in particular a gas Otto-cycle engine, comprising a plurality of cylinders, wherein each cylinder is provided with a respective pre-chamber, a pre-chamber gas supply conduit through which the pre-chambers can be supplied with fuel gas by way of a pre-chamber gas valve associated with the respective pre-chamber, wherein a respective aperture is arranged between the pre-chamber gas supply conduit and the pre-chamber gas valve, wherein at least one and preferably all of the apertures associated with a pre-chamber gas valve has such a small through-flow coefficient that the pressure which occurs at a maximum between the combustion cycles in the volume between the pre-chamber gas valve and the aperture does not reach the pressure prevailing in the pre-chamber gas supply conduit.

摘要： A method for operating a spark ignited engine, including forming a combustible mixture by mixing generally homogeneously a first fuel and air and introducing this mixture into the at least one cylinder in an intake stroke, and compressing the combustible mixture with a piston in a compression stroke thereby introducing a part of the combustible mixture into a pre-chamber. During the intake and/or the compression stroke, a second fuel is introduced into the pre-chamber at an introduction-time before start of combustion, and the second fuel is of the same or different chemical composition and/or concentration with respect to the first fuel, and a spark ignites in the prechamber. An amount of second fuel and/or the chemical composition of second fuel introduced to the pre-chamber and/or spark timing of the pre-chamber and/or an in-cylinder charge temperature is chosen such that a desired duration of combustion can be achieved.

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.
