Article Preview

Through combustion’s numerical simulation of the diesel engines with the high-pressured common rail system (Common-rail), this article researches the effect of injection pressure on the heat release rate, the emission quantity of nitrogen oxide and particulate matter. The results show that the advance of injection pressure could improve power and fuel economy performance. In order to reduce the emission quantity of nitrogen oxide and particulate matter, the earlier combustion should be controlled appropriately, when we enhance the injection pressure of Common-rail.
