| Abstract: | The pilot fuel supply advance angle and the substitution ratio of natural gas to diesel are two important factors influencing the dualfuel(natural gas and diesel) engine emission. Some experiments were carried out to determine the effects of these two factors on the dualfuel engine emission. The results shows that the dualfuel engine emission pollutants including THC, CO and NOx change greatly with the variation of these two factors. Based on the dualfuel engine emission characteristics, dynamic performance, et al. the optimal range of the pilot fuel supply advance angle and the substitution ratio of natural gas to diesel were obtained. |
