This paper explains the optimization of control parameters used for optimum control of torque and fuel delivered by the FIP of the Automotive engine. The parameters observed were fuel delivery, input current to driving motor, rpm of the pump, control rack travel and number of strokes. The fuel-injection system is the most vital component in the working of CI engine. The engine performance (power output, efficiency) is greatly dependent on the effectiveness of the fuel injection system and its parameters. The experiment is conducted on two MICO Bosch FIP of TATA Engine (TATA 207 and TATA Sumo FIP) as per DoE using three input parameters at different ranges and conditions. The mathematical models are developed for Torque and Fuel delivery of FIP. This paper also explains the optimization of control parameters using GA to study the optimum conditions for economic fuel delivery and optimum torque control
