Abstract

The effect of idling stop on $CO_2$ reduction was estimated, especially in the area of in-use vehicles. In order to know the fuel saving for each class of vehicles, a methodology to calculate the fuel saving was used along with a standard test using NIER-07 mode. Idling stop execution rate was estimated by analyzing the driving pattern of the in-use city buses, which shows about 75% at maximum. And this corresponds to about 5.4% reduction of the daily total fuel consumption. Finally, $CO_2$ reduction in the automotive sector was estimated, which concludes that, when idling stop device is used, about 480 thousand and 450 thousand tons of $CO_2$ could be reduced with in-use city buses and taxis, respectively. This amount corresponds to about 1.2% of $CO_2$ reduction in the automotive sector.
