Abstract

Bei gasbetriebenen Brennkraftmaschinen tritt das Problem auf, dass die maximal erzielbare Leistung durch eine reduzierte Frischluftmenge im Zylinder (2) der Brennkraftmaschine (1) begrenzt wird, weil ein Teil des verfügbaren Zylindervolumens durch das Autogas ausgefüllt wird. Zur Lösung dieses Problems wird erfindungsgemäß vorgeschlagen, das Autogas erst dann in den Zylinder (2) einzuspritzen, wenn der Zylinder (2) bereits mit der maximalen Frischluftmenge gefüllt ist. Dieses ist beispielsweise dann der Fall, wenn sich das Einlassventil (EV) in seiner Schließphase (a2) befindet oder wenn es bereits geschlossen ist. Wird in der Kompressionsphase (b) das Autogas eingespritzt, dann ergibt sich in vorteilhafter Weise eine entsprechend höhere Maximalleistung der Brennkraftmaschine.In gas-powered internal combustion engines, the problem arises that the maximum achievable power is limited by a reduced amount of fresh air in the cylinder (2) of the internal combustion engine (1), because a portion of the available cylinder volume is filled by the LPG. To solve this problem, the invention proposes to inject the LPG into the cylinder (2) only when the cylinder (2) is already filled with the maximum amount of fresh air. This is the case, for example, when the inlet valve (EV) is in its closing phase (a2) or when it is already closed. If the LPG injected in the compression phase (b), then advantageously results in a correspondingly higher maximum power of the internal combustion engine.
