Abstract:
A system for improving control of an event of an internal combustion engine comprising:an engine having a body driven for rotation by the engine and at least one of a fuel injection system, a fuel to air ratio mixture system and a spark ignition system;a first sensor responsive to at least one angular position of the rotating body to provide a signal at least when the body rotates through said at least one angular position of the body;an electronic circuit in communication with the sensor and determining an elapsed time of a first portion of a cycle of the engine, determining an elapsed time of a second portion of a cycle of the engine, comparing the elapsed time of the first portion of the engine cycle with the elapsed time of the second portion of the engine cycle to determine a time difference indicative of a load on the operating engine and producing an output signal to control the timing of at least one of the fuel injection, fuel to air ratio mixture, and spark ignition systems of the operating engine at least in part as a function of the time difference indicative of the load of the operating engine.
