    Abstract: The invention relates to a method for operating a spark ignition gas engine (100), preferably with fuel gas in the form of biogas by setting an ignition time (ZZP) of the spark ignition gas engine (100), comprising: mixing of air (2) and fuel gas (3) to form a combustible gas mixture (1) in a mixing arrangement (140), feeding in and igniting the combustible gas mixture (1) in the combustion chamber while setting an ignition time (ZZP) and burning the combustible gas mixture (1) while discharging exhaust gas (4) from the combustion chamber, further comprising the steps: detection of an exhaust gas temperature (T_AG) of the exhaust gas (4), predefining at least one reactor position (LRV) of a component of the mixing arrangement (140), setting the ignition time (ZZP) of the spark ignition gas engine (100) as a function of the exhaust gas temperature (T_AG) and the reactor position (LRV). The invention provides that the reactor position (LRV) is predefined as a manipulated variable by a mixture controller (30).

    Abstract translation: 本发明涉及一种用于操作火花点火气体发动机(100),优选地具有在生物气的形式的燃料气体,同时调整奥托燃气发动机的点火正时(ZZP)(100),包括:混合空气(2)和燃料气体(3) 的燃烧气体混合物(1)中的混合装置(140),供给和点火在燃烧腔室中的混合物(1)的燃烧气体的同时调整点火正时(ZZP)以及将该混合物(1)的燃烧气体燃烧废气的出口(4) 从燃烧室,进一步包括以下步骤:检测所述废气(4)的排气温度(T_AG),指定混合装置(140)的部件的至少一个节流位置(LRV),调整奥托燃气发动机的点火正时(ZZP)(100 )作为排气温度(T_AG)和节气门位置(LRV)的函数。 根据本发明规定,节气门位置(LRV)由混合控制器(30)预先确定为操纵变量。
