A Contact-Point Type Start of Injection Sensor for Diesel Engines 851585

A simple contact-point based start of injection sensor has been developed for use in closed-loop injection timing control systems. The main element in this sensor is a highly durable thin film deposited by an advanced ion plating process. This sensor is expected to provide accurate detection of start of injection over all speed ranges. Sensor transient response in the feedback loop is also expected to be fast compared to other types of sensors.This detecting method can easily be applied to many kinds of injectors because of its simple structure. The durability has been confirmed by extensive testing.
