Abstract
An ignition method for a multi-cylinder reciprocating gas engine wherein, in order to start a combustion cycle, a compressed, substantially homogeneous and not self-igniting combustion gas-air mixture contained in the corresponding cylinder chamber to be fired is ignited by the direct injection of a small amount of combustion gas. The injected small amount of combustion gas, which serves as the ignition gas, is injected onto a hot surface in the region of the combustion chamber. The beginning of the injection is predetermined depending on the position of the crankshaft, and is controlled by an engine control unit.
