Patent ID: 7047943

Claim:
An internal combustion engine comprising a throttle valve, an ignition system, a plurality of combustion chambers, a fuel delivery system adapted to deliver a fuel charge to each of the combustion chambers, a plurality of engine condition sensors adapted to detect associated engine condition data, and a control system, the control system adapted to receive the data from the engine condition sensors and further adapted to control operation of the fuel delivery system and the ignition system, the engine having a first operational state defined by a first range of throttle valve openings and a second operational state defined by a second range of throttle valve openings, and the control system having a default control condition wherein the control system controls the fuel delivery system in accordance with a first control mode with the engine running in the first operational state or controls the fuel delivery system in accordance with a second control mode with the engine running in the second operational state, the control system further being adapted to reduce engine speed upon a detection error of one of the sensors.
