【 摘 要 】

Based on the control research of diesel engine combustion emission pollutants, a reasonable numerical simulation study is carried out. At present, hydrocarbon fuel is a common fuel in transportation. Its combustion quality directly affects emissions. Reducing sulfur content and polycyclic aromatic hydrocarbons content in diesel can effectively reduce particulate matter emissions. Because of the poor atomization of diesel fuel, diesel in cylinder cannot be completely burned, resulting in the formation of soot, and diesel additives can increase the degree of combustion completion, and then optimize to achieve the effect of reducing soot. Therefore, the numerical simulation of pollutants is carried out and effective measures are taken to control combustion. The combustion model chosen here is Vortex Cluster Fragmentation Model 20, which is based on turbulent mixing rate.
