Abstract : The fluctuating loads encountered in all mobile applications give rise to the oscillations of speed of diesel engines which are the main cause of deterioration of the performance of these engines. This lowers the power output and fuel economy of engines used in mobile applications. Various attempts made to apply the control engineering to the engine governing problems have made it clear that an optimum matching of the parameters of engine, governor and load is necessary to achieve the best fuel economy and power parameters of the engine. The large number of parameters encountered which do not remain constant for the full speed and power range as well as during the entire service life of engine make the task of governing difficult in spite of the complexities introduced in mechanical governors. It is shown here that the microprocessor application to the governing of diesel engines is alone capable of providing the optimum control using the PID and other advanced algorithms for various applications during the entire service life of engine.
