Abstract:In order to meet the requirements of IMO TierⅡ, Guangzhou Diesel Engine Factory Co., Ltd. has carried out the research and tests on different technologies to reduce NOx emission on G32 diesel engine, including:supercharging and intercooling technology, atomizing spray technology, optimizing fuel oil temperature at engine inlet, and Miller timing, etc. The results show that all the above mentioned technologies could reduce NOx emission to a certain degree. And with all these being synthesized and optimized, G32 diesel engine could not only meets NOx emission requirements of IMO TierⅡ, but also keeps the good economic indicator.
