Abstract

The introduction of China Ⅵ emission regulation for diesel engines makes DPF a necessary aftertreatment device to meet the emission requirement, and DPF regeneration technology is the core technology of China Ⅵ diesel engine. The aftertreatment type of China Ⅵ diesel engine is complex, and the inappropriate regeneration verification test will lead to wrong test results. According to the occurrence cycle of regeneration, DPF regeneration was divided into two types of continuous regeneration and periodic regeneration. The verification processes of diesel engine regeneration were introduced in detail under different regeneration types, and the soot emission regeneration law of China Ⅵ diesel engine was acquired through the experimental research of diesel engine regeneration for different regeneration types. In view of the difficulties of periodic regeneration verification, an innovative alternative to cyclic test was then proposed, which could effectively calculate the regeneration factor. The experimental process of periodic regeneration verification was hence optimized, which shortened the verification time of periodic regeneration and greatly reduced the verification cost.
