对两台相同的国五SCR柴油机，分别燃用国三柴油和国五柴油进行了125h耐久台架试验，以模拟北京市国五车辆驶出北京后较长时间燃用较差油品后的性能和排放劣化情况。在耐久试验前后，均使用国五柴油进行了性能和排放试验，作为参照。结果表明：燃用国三柴油对国五柴油机的动力性影响不大；但柴油机的排放劣化程度明显加重。

A 125h durability bench test is conducted on two identical State-V diesel engines with SCR sys-tem fueled with State-III and State-V diesels respectively to simulate the performance change and emission deteriora-tion of Beijing's vehicles when running in other localities with lower grade fuel for a relatively long period of time. Before and after durability test, performance and emission tests are carried out with State-V diesel as reference for comparison. The results show that fueling with State-III diesel has no apparent effects on the power performance of State-V diesel engine, but leads to its relatively severe emission deterioration.
