Abstract (en)
[origin: DE3400034A1] A substantially instantaneous ignition of an ignitable fuel mixture during the compression phase in the volume of the combustion chamber of an alternating or rotary piston machine may be obtained together with a combination of a lean mixture and a reduction of noxious product emission by introducing high energy rays in the form of a plurality of unfocused laser rays (30) into the combustion chamber so as to generate in the combustion chamber at least at the ignition time a layer traversed by a plurality of those rays (30), the arrangement being such that the wall of the combustion chamber, and during the compression phase, the front surface of the piston facing said walls are close to the layer and that, at the ignition moment, at least in a surface area of the layer, elementary ignition processes are triggered so that the flame fronts providing from the neighbouring elementary ignition processes meet before a displacement of the front surface of the piston during the expansion stroke.
