| Abstract: | Taking a 4-cylinder turbocharged DI diesel engine as the prototype,the diesel engine exhaust emission was researched on the premise of optimized injection timing and EGR opening on a special test bench by using diesel oxidation catalyst(DOC) and particulate oxidation catalyst(POC) technology.Then the influencing rules of DOC and POC on diesel engine emission were summarized.The result shows that the exhaust emission can reach Euro Ⅳ standard by selecting the appropriate location of DOC and POC under the condition of optimizing injection timing and EGR opening. |
| Keywords: | diesel engine diesel oxidation catalyst(DOC) particulate oxidation catalyst(POC) emission control Euro Ⅳ standard |
