Microprocessor Controlled Fuel Injection for Automotive Diesel Engines 830576

An electronically controlled fuel system has been developed which enables the injection timing and fuel delivery to be adjusted from engine cycle to cycle using a small micro-computer and a solenoid operated injector.The injector uses a powerful solenoid to control the needle lift of a standard injector and employs pressure time metering to regulate the fuel delivery. The microcomputer is used to determine the required timing pulses which are used to control the current in the solenoid.The maximum delivery of the injector is 60mm3/injection and the system has been successfully tested on an 1800 cc IDI four cylinder engine fitted with Pintaux fuel injectors.
