Consideration on Regeneration Frequency and PM Collection Performance of Diesel Particulate Filter (DPF) based on Actual Road Driving Data of Heavy-duty Vehicle

Abstract

A measurement system (SEMS) using NOx sensor, etc. was attached to a heavy-duty vehicle for the transportation business, and exhaust gas data and vehicle driving data during the transportation business driving was acquired for a long period of time. Based on these data, we investigated the driving conditions such as general road driving, highway driving, idling, etc. and the frequency of DPF automatic regeneration, and considered the relationship between the frequency of DPF automatic regeneration and the deterioration of PM collection performance.
