ABSTRACT:
The invention concerns a method for operation of a four-stroke reciprocating internal combustion engine with a homogenous lean base mixture of air, fuel and retained exhaust, as well as with compression ignition and direct fuel injection into a combustion chamber with gas displacement devices.
In order to keep the design cost low for this concept, the reciprocating internal combustion engine is operated at partial load with compression ignition and preferably mechanically controlled exhaust retention, whereas operation in the full load and high partial load range occurs as a spark ignition engine.
