Kind Code:
A1
Abstract:
A combustion engine (1) is provided, comprising: a spark plug (2) for igniting an air-fuel mixture in a combustion chamber (4), and a control device (24) capable of controlling sparking actions of the spark plug (2), wherein the control device (24) is configured to selectively carry out a spark-ignition stroke in which the air-fuel mixture is spark-ignited by the spark plug (2) and a no-spark-ignition stroke in which generation of a spark by the spark plug (2) is suppressed, and wherein the control device (24) is configured to adjust a factor (air-fuel ratio) of the combustion engine (1) based on whether a no-spark combustion has been detected or not in the no-spark-ignition stroke.
