Effect of diesel sulfur content on the emission of China Ⅵ heavy diesel engine
Based on a China Ⅵ heavy-duty diesel engine equipped with a full-flow engine plat-form,three kinds of diesel with different typical sulfur contents were burned respectively,and the differ-ences of NOx,HC and CO emissions under the world uniform transient cycle(WHTC)were compared.The results show that with the increase of diesel sulfur content,NOx emission will also increase signifi-cantly,but HC and CO emissions have been maintained at a low level without significant change.
