In order to follow the development trend and meet the market demand of domestic non-road agricultural machinery products,a 4-cylinder non-road diesel engine was selected as the research object in this paper.The high-pressure common rail+EGR+DOC+DPF technology was adopted,the China non-road stage Ⅳ emission test was carried out.By selecting and matching hardware such as turbochargers,fuel injectors,and injector gaskets,combined with optimization of rail pressure,injection timing,and EGR valve opening,to make the diesel engine achieve optimal fuel economy while passing through the China non-road stage Ⅳ emission limits.
