The fuel is not injected when the driver doesn't push acceleration pedal of a vehicle with engine speed higher than about 1,500rpm in mid speed range. This is called "fuel-cut function" and almost every modern vehicle is equipped with this function. This is activated on downhill part of roads most often. Therefore the vehicle exhausted CO2 can be zero if the driver could recognize this downhill part of roads. The reduction rate of CO2 using this fuel-cut function in the downhill part of two different roads was measured in this study. The reduction rate is about 4% and this rate could be higher if optimized for different declined angles or the length of downhill part of roads. And this fuel-cut driven part of roads can be used in road painting policy for reduction of vehicle exhausted CO2.
