An effective fuel injection for reducing harmful substances such as hydrocarbon (HC) and carbon monoxide (CO) of vehicle exhaust gas is researched in this study. Reductions of fuel injection quantity during engine cold condition is very effective, because major portion of HC and CO, both unburned harmful substances, are emitted in the phase. The fuel reduction control, based on sliding mode control theory, uses feedback from measured Air/Fuel ratio by linear A/F sensor to avoid engine torque fluctuation. It is confirmed that the fuel control is very effective to reduce exhaust emissions by simulations and experimental results.
