Integration of electronics fuel regulator in a single unit for 4 cycle engines

摘要

A fuel injection system for a hydro carbon engine is provided with a simplified electronic governor system for controlling the maximum speed of the engine. The governor system is operatively associated with an electronic control unit (ECU) for operating the engine. A pulse width modulated fuel valve is provided with a pressure intensifier device enabling the fuel system to use low pressure signals in providing a fuel supply to the engine. The fuel system further is provided with a throttle body having the ECU, the fuel valve and the governor system integrated with on another in a single package for mounting on the engine.
