【Abstract】 In order to reduce diesel emissions and noises, meet the more and more strict diesel emission regulations, this paper develops dual-spring injectors of P series for FAW company’s leading products-the CA6DF Diesel, which equipped with single-spring injectors. The dual-spring injector has simple and reasonable structure, good manufacturing heritage and relatively low cost, and can use its original nozzle spouse. Its injection rate pattern is first slow, and then rapid, this can reduce NO X emissions and combustion noises while maintaining good power and economical performance.更多还原
