With the rapid development of vehicle diesel engine, diesel engine emission problem has attracted great attention, and the country has promulgated more and more strict emission laws and regulations. Although many diesel engines begin to use high pressure common rail system to reduce fuel consumption and reduce emissions, but in our current situation, the mechanical fuel injection pump because of the advantages of cheap price, good reliability, convenient maintenance are still favored by many users.
According to the research on Miller cycle coupling injection Angle in the literature, it is found that the NOx generation can be significantly reduced, but it will lead to the deterioration of fuel consumption and the increase of soot emission. The existing researches mainly focus on the single factor of injection Angle, while the researches on the synergistic effect of injection Angle and multiple injection under multiple injector arrangement have not been reported. In this paper, a low-speed Marine diesel engine with large cylinder diameter is taken as the object. Three-dimensional CFD numerical simulation method is used to study the mixing and combustion process under the synergistic effect of multiple injection and fuel injection Angle optimization under EGR atmosphere. The results will provide theoretical guidance for the independent research and development of a new generation of low speed two-stroke Marine diesel engine in China.
The maximum pressure at the pump end is 100 MPa, and the maximum injection pressure at the nozzle end can reach 140 MPa. The higher the injection pressure, the more it can promote the oil and gas mixing, and accelerate the diffusion combustion at the later stage while delaying the injection of oil. Reducing the injector aperture can effectively reduce the diameter of spray particles, promote the further mixing of oil and gas, combustion more fully, reduce the generation of dry carbon smoke, and ultimately achieve the purpose of reducing PM.
