摘　　要：在实际道路行驶条件下,测量了两辆并联混合动力客车(PHEV)的油耗和电量消耗,并分别采用SAEJ2711和GB/T19754推荐的方法计算等效油耗,评价PHEV的节油效果,并考察了整车质量和空调运转对PHEV燃油经济性的影响。结果表明,K值小于1%时,分别按SAE J2711(不修正)和GB/T19754(进行电量修正)两种方法得到的100km能耗的相对差别在0.7%以内;PHEV相对传统车辆的节油效果明显,两辆PHEV的节油率分别为14.78%和15.65%;在空调开启工况下,PHEV的100km等效油耗比空调关闭工况下增加42%以上。Under real-world driving conditions,the fuel and electricity consumptions of two parallel hybrid electric vehicles（PHEVs） are measured and their equivalent fuel consumptions are calculated with the methods recommended by SAE J2711 and GB/T19754 respectively to evaluate the fuel saving effects of PHEVs,and the effects of vehicle mass and air conditioner（AC） operation on the fuel consumption of PHEVs are also investigated.The results show that when K is less than 1%,the relative discrepancy between fuel consumptions in L/100km obtained as per GB/T 19754（with electricity correction） and SAE J2711（without correction） respectively is within 0.7%.PHEVs have obvious fuel saving over conventional vehicles with a fuel saving ratio of 14.78% and 15.65% for two PHEVs respectively.And the equivalent fuel consumption in L/100km of PHEVs with AC on increases by over 42% compared to that with AC off.
