Abstract

The present invention as disclosed herein is directed to an engine with associated decompression device which is adapted to drive an onboard generator/electric motor. The present invention comprises an engine speed sensor means for detecting the speed of rotation of the engine, and a fuel injection control means for controlling the injection of a fuel in the engine. The decompression device is, for example, moved from an operative condition to an inoperative condition or vice versa in response to a sensed signal from the engine speed sensor means. The fuel injection control means is operable to initiate or stop the injection of the fuel in response to a sensed signal from the engine speed sensor means. The present invention provides an onboard electrical generating system which better controls vibration and exhaust emissions when the engine, particularly an onboard generator drive engine, is cranked and stopped.
