| Abstract: | This paper described turbocharger optimization, EGR cooler radiating area calculation, ANSYS model analysis, ESC ＆ ETC test of engine with EGR. By choosing one kind of POC ＆ DOC with EGR,the engine test results showed that prototype engine with EGR ＆ POC ＆ DOC meets NS4 Emissions legislation. On the other hand,the engine test results showed that prototype engine with EGR ＆ DOC does not meet NS4 Emissions legislation. |
