Abstract
An internal combustion engine has a cylinder with a combustion chamber delimited by a reciprocating piston that drives a crankshaft rotatably supported in a crankcase. The internal combustion engine has an intake passage, an exhaust connected to the combustion chamber, a device supplying fuel, and a control device controlling at least one operating parameter of the internal combustion engine. The internal combustion engine is operated in that a pressure is measured in operation of the internal combustion engine, an adjustable value for at least one operating parameter of the internal combustion engine is deteremined based on the measured pressure, and the determined adjustable value is set for optimized running of the engine.
