The Nippondenso Electronic Control System for the Diesel Engine 880489

This paper describes the methods of operation and functions of advanced fuel injection controls, and the results of engine testing for the “Learning Control”, a function which was developed to control diesel engines that makes the most of the flexibility found in software used for electronic control. In-depth of study of the “Learning Control” function, confirms that this function can provide stability in engine performance by automatic compensating for injection quantity deviation in fuel injection pump operation. This paper also outlines concepts for insuring the safety of system operation during the “Learning Control” stage.
