Spark suppression for a genset

摘要

A method for operating a four-stroke internal combustion engine including a crankshaft coupled to a piston, which includes moving the piston in accordance with a sequence of four different strokes; mechanically driving an electric power generator with the crankshaft during the operating of the engine; generating a first sensor signal indicative of each revolution of the crankshaft with the crankshaft rotating twice during the sequence of four different strokes; providing a second sensor signal corresponding to a working fluid characteristic of the engine, the working fluid characteristic changing during the sequence of four different strokes of the piston; and timing ignition of the engine as a function of the first sensor signal and the second sensor signal.
