Cheng Zuquan，Wu Shaojun，Liang Pengfei

Abstract：This paper， mainly through testing the WLTC cycle of a PHEV vehicle which equipped with a 1.2L turbocharged gasoline engine， studied the effects of torsion limitation depending on engine water temperature on vehicle emission and fuel consumption. The test found that the used torsion limitation depending on engine water temperature in first phase of the WLTC cycle can effectively reduce engine PN emission and improve fuel consumption.

Key words：torsion limitation， PHEV vehicle， PN emission， fuel consumption
