초록	In general, it has been mentioned that the performance of diesel engine is more excellent than gasoline engine's in terms of a fuel efficiency and durability so that it can be applied to a heavy duty commercial vehicle. However, the NOx and PM emitted from the diesel engine are remained to overcome and its regulation is reinforced recently. While a current diesel engine is able to satisfy the EURO-4 regulation through SCR only, it is not sufficient to meet EURO-5 regulation. This paper suggests the Urea-SCR system configuration to meet EURO-5. From the results, In the case of the DOC+SCR system configuration, although the EURO-5 can not be met with only map based control system, advanced control algorithm with map base was enough to meet the regulation. But high concentration of NH₃ was measured in tailpipe. With same configuration system of DOC+SCR, the sensor based closed loop control system was necessary to meet the regulation with low ammonia slip. Finally, a temperature and exhaust emission trend were evaluated on ESC and ETC mode with DPF and SCR combination system, After test, the result was that the DOC+SCR+DPF system was more efficiency than DOC+DPF+SCR
