Abstract
The fuel is not injected when the driver doesn't push acceleration pedal of a vehicle with engine speed higher than about 1,500rpm above mid vehicle 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 a highway most often. Therefore the vehicle-exhausted $CO_2$ can be zero in this downhill part if the driver could recognize this part of highway. We compared the vehicle-exhausted $CO_2$ emission when using fuel-cut function with the $CO_2$ mass when without using this function in this study. We found that the $CO_2$ emission reduced with fuel-cut function and measured the reduction rate of vehicle-exhausted $CO_2$ mass with this test results. The exhausted $CO_2$ mass of a passenger car(2,000cc engine volume) is reduced by 4% with this function used. This $CO_2$ reduction effect can be achieved if the downhill part of a highway is painted with a specific color. And this road painting can be included in the highway road rehabilitation policy.
