Abstract:
An ignition method for a multi-cylinder reciprocating gas engine comprising: injecting a compressed and essentially homogeneous, non self-igniting combustion gas-air-mixture present in the respective cylinder chamber to be fired through directly injecting a small metered amount of combustion gas, as ignition gas, onto a hot surface for the purpose of starting an operating cyclespecifying and controlling the start of the injection in dependence on the crankshaft position by use of an engine control unit;providing the small amount of ignition gas to be metered by removing the ignition gas from an ignition gas accumulator that is assigned to a respective cylinder via a controllable ignition valve that is connected between a combustion gas supply and the cylinder chamber; and,supplying the ignition gas accumulator with operating gases from the cylinder chamber at the maximum combustion chamber pressure via a valve arrangement.
