摘　　要：对3款典型怠速起停轻型乘用车,试验并分析了其实际节油潜力和排放。在实验室和实际道路上,在多种测试循环下,测量了功能ON与功能OFF的油耗。结果显示:在两种代表中国城市道路行驶状况循环下,各车节油表现显著,均优于新欧洲驾驶循环(NEDC)的结果。在中国几个城市道路上开展的车辆油耗对比实证试验节油表现,也优于NEDC循环下的结果。比较多个循环下怠速起停功能ON与OFF,ON排放结果与OFF排放结果大致相当。借鉴美国循环外测试评价方法和欧盟Ecoinnovation测试评价方法,并结合中国的交通、气温特点来构划的中国怠速起停循环外奖励测试方法,可以测出中国实际道路上额外节油潜力。Real world fuel saving potential and pollutant emission were tested and analyzed for some typical start-stop vehicles for 3 light duty vehicle （LDV） passenger cars. The fuel consumptions when start-stop function ON and OFF were tested in lab and on road in different driving cycles. The results show that the fuel savings potentials for every car tested both in lab and on road in two driving cycles representing China city traffic conditions are better than that in New European Driving Cycle （NEDC） cycle. Real-world road tests data in several cities in China comes to a same conclusion. The overall pollutants are comparable between startstop function ON and OFF in the emission tests for LDV passenger cars in different driving cycles. Start-stop off-cycle credit should be evaluated and granted by means of lab tests taking account of the traffic characters and environment temperature in China while referring to US＇s off-cycle/EU＇s Eco-innovation test and evaluation method. This approach is able to evaluate start-stop technology＇s additional fuel saving in real world in China.
