The idling distribution characteristics of NEDC, WLTC and CLTC conditions were analyzed, and the exhaust emissions and fuel consumption of three light gasoline vehicles when the idling start-stop function was turned on and off under different cycle conditions were measured. The effects of idling start-stop function on light vehicle fuel consumption and emissions under different cycle conditions were analyzed. The results show that the vehicle fuel saving rate of the idling start-stop function in three cycle conditions is WLTC, NEDC and CLTC conditions from low to high. The idling start-stop function has little effect on vehicle gaseous pollutant emissions. On the whole, the the activation of idling start-stop function increases the THC and CO emissions and reduces NOx emissions.
