【Abstract】This paper elaborates on the control of THC and NOx emissions in PFI engines,including the control verification effects of different excess air coefficients(air-fuel ratio)and ignition angles,and makes suggestions for the emission control of PFI engines for China VI models.
【Key words】air-fuel ratio;ignition angles;THC and NOx emissions
