Abstract

In a heavy-duty diesel engine

3 types of diesel fuel(automotive National-V diesel fuel and 2 types of modified diesel fuel)with different physicochemical characteristics were burned to investigate the effects of the modified diesel fuels on the emission of pollutants. The effects of operating condition

air-to-fuel ratio and modified diesel fuel on the conventional pollutants NO

and T

HC from heavy-duty diesel engine were analyzed. The effects of working condition

air-to-fuel ratio and modified diesel fuel on the carbon components in particulate matter were discussed. The results show that compared with the low speed-25% load condition

the rated speed-25% load condition has higher air-to-fuel ratio

lower emission of conventional pollutants

and higher emission of aldehydes

ketones and aromatic hydrocarbons

e.g. about 13% increase in aldehydes and ketones

and slightly higher emission of organic carbon and elemental carbon. Compared with the automotive National-V diesel

under higher air-to-fuel ratio condition

the NO

emission of the diesel with low aromatic hydrocarbon content increases by about 15%

emission increases slightly

and THC emission decreases slightly; the NO

emission of the diesel with lower latent heat of vaporization increases by about 30%

emission increases by about 13%

and THC emission decreases by about 28%; and the PAH emission of the diesel with lower aromatic hydrocarbon decreases by about 50%

and the PAH emission of the diesel with lower latent heat of vaporization decreases by about 25%. The emission of aldehydes and ketones of the 2 modified diesel fuels is decreased by about 15% compared with that of the National-V diesel fuels.
