Fuel management and control in a vehicular system

Abstract

This project simulates a working model of a vehicular system which gives a good tradeoff between power, economy and emissions. The optimum air-fuel ratio for this system to be designed is 14.6. The quantity of oxygen content in the exhaust gas(EGO) is obtained with the help of a sensor. The output from this sensor is a sign of air fuel ratio and it gives the necessary feedback for closed loop control. When high oxygen level is shown by the sensor, then as per the control law, the fuel rate will be increased. Subsequently if the sensor indicates a fuel rich mixture, when the level of residual oxygen is very low, then this leads to reduction in fuel rate.
