摘要
高压共轨+SCR技术是发动机实现国Ⅴ排放两种典型路线的一种,而低硫燃油的供应是柴油车实现国Ⅴ排放标准的重要支撑。高硫含量燃油的长期使用势必会导致发动机及后处理系统产生故障,影响顾客的正常使用。以某种轻型客车(GVW>3.5t)匹配SCR后处理为例,着重探究SCR后处理在整车实际应用中的耐硫性。
SCR & high pressure common rail is one of the typical ways to realize the Euro V emission standard. In the mean time, the supply of low-sulfur fuel is an important support to achieve Euro V emission of diesel vehicle. A long time usage of high sulfur fuel will lead to OBD Mann. Seriously it will affect the use of custom. The fuel sulfur resistance of SCR system in the practical application of the vehicle ( GVW 〉 3.5 t) was researched.
