Abstract (en)
[origin: WO2019015844A1] The invention relates to a method and to a device for increasing the possible compression ratio of internal combustion engines of motor vehicles in the case of varying fuel quality in an internal combustion engine having a combustion chamber (12) for burning the fuel, the device comprising an apparatus (21, 22) for determining the antiknock property of the fuel, an apparatus (40, 22, 23) for sensing the operating state of the internal combustion engine, a water tank (30), and a feeding apparatus (31, 32, 27, 28, 29) for the water. In the method, the antiknock property of the fuel is determined and the operating state of the internal combustion engine is sensed. A need for a feed of water to the fuel is determined therefrom.
