[摘 要]：車用柴油機(jī)主要采用微粒捕集器(DPF)過(guò)濾方法處理排氣微粒，為清除過(guò)濾體中的微粒，完成DPF再生，需要在DPF入口設(shè)置燃燒器。本文設(shè)計(jì)了蒸發(fā)式DPF再生燃燒器，并進(jìn)行和臺(tái)架和實(shí)車試驗(yàn)，試驗(yàn)表明該燃燒器能夠在發(fā)動(dòng)機(jī)較大的工況范圍內(nèi)，很好地完成DPF再生。
Abstract: Diesel engine for automobile mainly adopts diesel particulate filter (DPF) method to deal with the exhaust particulate. In order to eliminate the particulate in the filter and complete DPF regeneration, the burner needs to be set at the entrance of DPF. This paper designs the evaporation-type DPF regenerative burner, and makes the bench and the real vehicle test. The test shows that the burner can complete DPF regeneration well within the working scope of the larger engine.
Introduction
隨著汽車保有量的與日俱增，汽車排氣對(duì)人類健康的危害和對(duì)環(huán)境的污染也日甚一日。為此，世界各國(guó)都制定了越來(lái)越嚴(yán)格的汽車排放法規(guī)，目前法規(guī)限定的污染物主要是碳?xì)浠衔铮℉C）、一氧化碳（CO）、氮氧化物（NOx）和微粒（PM），其中柴油車需要重點(diǎn)控制的是氮氧化物（NOx）和微粒（PM）[1]。
With the increase of the automobiles on hand, the automobile exhaust does more harm to the human health, and the corresponding environmental pollution gets worse and worse. Therefore, the countries all over the world have made more and more stringent automobile emission regulations. At present, the main pollutants which are stipulated by the regulations
