| Abstract: | By analyzing the performance of a diesel matched with a waste-gated turbocharger,this paper makes it clear why the performance of a diesel with a waste-gated turbocharger becomes worse at high engine speed.An example of improving diesel performance at low engine speed with VNT is presented,and the controlling method and its engine test result are also presented here.The result shows that the VNT and the controlling method make the engine work well at both low engine speed and high engine speed. |
