| Abstract: | The correction of EGO set point voltage and adjustment of A/F modulation are the key technologies of A/F calibration in match of TWC with EFI engine.In order to study the effects of these two factors on the engine emissions,experimental investigations have been carried out on an engine test bench.The results show that the EGO set point voltage and A/F modulation have significant influences on the emissions,and careful calibration on the engine can greatly improve the of conversion efficiency. |
