柴油机DPF系统累碳量估算方法研究

Research Progress in Estimation Method of Accumulated Carbon in Diesel Engine DPF System

本文以柴油发动机的后处理DPF系统为研究对象,开展对其累碳量估算方法的研究。首先介绍DPF系统并分析其失效边界,然后详细阐述目前应用较为广泛的三种DPF累碳量估算方法,并分析其各自存在的问题,最后总结并为DPF累碳量的进一步研究明确方向。

In this paper, the diesel engine aftertreatment DPF system is taken as the research object, and the method of estimating the carbon content of the diesel engine is studied. First introduced the DPF system and analyze the failure boundary, and then elaborates on the current application of three DPF wide tired carbon estimation methods, and analyzes their existing problems, finaly summarizes and points out the direction for the further study of DPF tired carbon.
