摘要： A method of operating an engine is disclosed, which includes determining a peak power condition for the engine, measuring a temperature associated with the engine at said peak power condition, comparing the temperature measured with a previously determined temperature associated with a known peak power condition of the engine, determining an offset value based on the comparison made in step, controlling at least one of an air-fuel mixture delivered to the engine or ignition spark timing based on said offset value. Various engine fuel delivery systems, carburetors, fuel injection and control systems also are disclosed.

摘要： A system for managing ignition of a light-duty internal combustion engine during starting includes a charge winding used to create an ignition pulse; a first signal generated by the charge winding that indicates the speed of an engine; a second signal generated by the charge winding that indicates a piston position of the engine; a switch coupled to the charge winding for controlling the ignition pulse; and a processing device that receives the first signal and the second signal, wherein the processing device activates the switch when a comparison of the received first signal and second signal indicates that a piston is positioned at approximately top dead center (TDC).

摘要： A capacitive discharge ignition (CDI) system that can be used with a variety of light-duty internal combustion engines, including those typically employed by lawn, garden, and other outdoor equipment. According to one embodiment, the CDI system includes an ignition module having a first switching device that shorts a charge coil during an initial portion of a charge cycle. Subsequently, the first switching device is turned ‘off’ so that a flyback charging technique charges an ignition capacitor. A second switching device is then used to discharge the ignition capacitor and initiate the combustion process.
