Internal combustion engine and method of operating the same

An internal combustion engine ( 20 ) has a cylinder ( 1 ) wherein a piston ( 2 ) is mounted. The piston ( 2 ) drives a crankshaft ( 10 ) which is rotatably journalled in a crankcase ( 11 ). The piston ( 2 ) delimits a combustion chamber wherein an air/fuel mixture is compressed and is ignited by an...

Beschreibung
Zusammenfassung:	An internal combustion engine ( 20 ) has a cylinder ( 1 ) wherein a piston ( 2 ) is mounted. The piston ( 2 ) drives a crankshaft ( 10 ) which is rotatably journalled in a crankcase ( 11 ). The piston ( 2 ) delimits a combustion chamber wherein an air/fuel mixture is compressed and is ignited by an ignition device ( 19 ). The ignition time point (Z) is determined in a first operating state of the engine ( 20 ) in accordance with a first characteristic line ( 22 ) and in a second operating state of the engine ( 20 ) in accordance with a second characteristic line ( 23 ). A switching element switches over between the first characteristic line ( 22 ) and the second characteristic line ( 23 ) in dependence upon an engine characteristic variable. A method for operating the engine ( 20 ) provides that an engine characteristic variable is determined during operation of the engine ( 20 ) and that a switchover between the ignition characteristic lines ( 22 ) and ( 23 ) takes place for a pregiven change of the characteristic variable.
