Latest Patents
Lienesch holds a patent for a "Method and apparatus for accurately locating piston top dead center." This invention involves an encoder device that produces a reference signal pulse and a series of encoder signal pulses during each crankshaft revolution. A microwave signal of a substantially constant amplitude and frequency is coupled through a microwave probe into the combustion chamber of a selected reference cylinder of the engine. The reflected microwave signal waveform is processed to determine the encoder signal pulse count at which the piston top dead center position occurs. This technology allows for precise ignition timing adjustments relative to the piston position.
