ENGINE CONTROL STRATEGY DEVELOPMENT USING THE RICARDO MICROPROCESSOR ENGINE CONTROL UNIT

The advent of electronic management systems for the control of internal combustion engines requires a systems approach to engine and control unit design. To augment its traditional expertise in the field of internal combustion engine design and development, Ricardo has developed a Microprocessor Engine Controller (MEC) for the development of engine control strategies. Emphasis has been placed on producing a unit capable of accepting a large number of control input variables and a wide range of possible control outputs. The unit can thus be used to control fuelling, timing and/or EGR rates on both diesel and gasoline engines. An ergonomic user interface allows the ready modification of control parameters during engine running both on the test bed and in the vehicle and these can be retained within the unit's non-volatile memory for later examination by the test engineer.
