ELECTRONIC ENGINE CONTROL SYSTEMS FOR THE SMALLER PASSENGER CAR

The objective of this study is to clarify the requirements for an engine control unit and a control strategy in case these systems are applied to smaller engines and smaller vehicles and where high accuracy of control is needed. An experimental control unit has been developed. Both transient and steady state compensation controls for fuel injection and ignition timing have been investigated. The requirements for conversion time of the analog to digital converter, the interpolation logic for crank angle signal, and the compensation circuitry have been clarified. The effectiveness of the compensation control, asynchronous fuel injection, and the adaptive control of air to fuel ratio have been demonstrated.
