Abstract

An engine operational control unit for an internal combustion engine which protects an engine in the event of abnormal condition of the throttle mechanisms by discontinuing operation of the ignition or the ignition and fuel injection dependent upon engine speed. In this way, the engine is protected from overheating if operating at a high speed, and from wetting or fouling of the spark plugs if operating at a lower speed, if abnormal conditions prevail.
