According to the requirements of PVE proposed in the China 6 Emission Standard for light-duty vehicles, this paper compares a fault code respectively from cooling system monitoring, oxygen sensor monitoring and integrated component monitoring of Spark Ignition Engines, and analyzes the diagnosis principles and simulation methods under three engine control systems in detail. The results show that the fault diagnosis principles for UAES system and Bosch system are similar, and the simulation methods can learn from each other. The fault diagnosis principles of the two systems are different from those of Delphi system, and the simulation methods depend on the fault failure mode.
Key words: China 6 Emission Standard / OBD / PVE / Diagnostic Trouble Code (DTC)
