A mathematical method for obtaining the optimum values for a direct injection diesel engine design is developed using a system theory which is called "The Method of System-Model Transformation". Optimum values of the design and operating parameters, such as : number of nozzle holes, diameter of nozzle holes, diameter of toroidal, swirl ratio, clearance volume, injection timing, injection duration, closing timing of the intake valve and opening timing of the exhaust valve, are obtained for the minimum value of performance index which represents engine power, fuel consumption, nitric oxide emissions and soot masses.
