摘　　要：通过试验得到了轻型汽油车达标第三阶段油耗限值标定的几种方法,主要包括怠速启停装置(BSG)、小速比变速箱及低滚阻力轮胎应用。3种不同的方法均可以使样车的油耗得到一定程度上的降低。怠速启停装置(BSG)可以使样车的油耗降低4.0%～5.0%,而小速比变速箱和低滚轮胎可以为油耗分别带来3.0%～4.0%和1.0%～2.0%的降低,几种方法组合使用可以使油耗降低8.0%～10.0%,从而为更严格的油耗限值达标提供依据。Abstract. Through experiments, the three test methods to decide the third stage fuel consumption limit are obtained, including the Belt Driven Starter Generator （BSG）, small ratio gearbox and low rolling resistance tire. All three methods can be used to reduce the Vehicle fuel consumption： BSG device can reduce the fuel consumption 4.0%～5.0%, and the small ratio transmission and low rolling tire are 3. 0%～4. 0% and 1. 0%～ 2. 0% respectively. The three combined method can reduce the combination 8.0%～10.0%, so as to offer the references for the more stringent fuel consumption limitation.
