Reduction of diesel engine emissions is now getting more and more focuses from automobile manufacturers as the legalization is becoming stricter. In this paper we use AVL FIRE to simulate and analyze the influence of ω-type combustion chamber shapes on raw emissions of a diesel engine. We get the conclusion that the trend of original exhausts, NOx and soot, decreases without power loss with the ratio TDD of throat diameter and depth of the chamber reducing. And considering the original emission control technologies of the experiment engine, a smaller ratio TDD will contribute to better emission.
