The invention relates to an apparatus and a method for determining a Einblaszeit and / or a cylinder of an engine 19 amount to be supplied a liquefied gas fuel - such as LPG, natural gas (CNG), liquefied natural gas (LNG), biogas or hydrogen (H 2 ) - for operation of the engine 19 in a bivalent or trivalent fuel operation, wherein the device is arranged so that the determined injection time of the liquid gas fuel depends on a determined calorific value or a determined gas mixture characteristic value. A gas mixture analysis module 7 serves to optimize the combustion. A gas-sensing device allows a gas type of a vehicle even at low temperatures. |
