Patent ID: 7536983

Claim:
A method for operating an internal combustion engine that is a single cylinder two-stroke engine that comprises a cylinder with a combustion chamber, which combustion chamber is delimited by a reciprocating piston that drives a crankshaft rotatably supported in a crankcase, wherein the internal combustion engine further comprises 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 method comprising the steps of: a) measuring a pressure in operation of the internal combustion engine; b) determining an adjustable value for at least one operating parameter of the internal combustion engine based on the measured pressure of the step a); c) setting the determined adjustable value of step b); wherein in the step a) the pressure in the crankcase is measured at a first predetermined crankshaft angle during a compression phase and is measured at a second predetermined crankshaft angle during an expansion phase; and wherein the crankcase is closed off at the first and second predetermined crankshaft angles.
