Title:
METHOD AND CONTROL DEVICE FOR OPERATING A SPARK IGNITION GAS ENGINE
Document Type and Number:
WIPO Patent Application WO/2012/072195
Kind Code:
A3
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).
