摘要:为了满足国V标准，采用了DOC+SCR系统对柴油机排放进行有效控制。采用一套气助式系统，在ESC/ETC/WHTC三种循环方式下进行了多重试验验证，得到了相应试验工况的排放数据，较原机排放有了很大提升，证明了该系统的实用价值。

Abstract: in order to meet the standard V standard , the DOC+SCR
system is used to control diesel emissions effectively.A type of gas-assist
system was used to verify the system under the three cycles(ESC/ETC/WHTC) Compared
with the original engine emission data,the emission of the whole system has
improved.And which proves the system in reducing emissions of heavy-duty
diesel.
Key words:diesel engine; DOC+SCR system; emission test; standard V
