柴油车综合型排气净化装置的设计研究

Design of Integrated Purification of Low-emission Equipment on Diesels

鉴于目前我国柴油车保有量逐年增加,污染问题日益严重的背景下,本文设计研制了一种柴油车综合型排气净化装置。发动机台架初步试验结果表明:该排气净化装置对发动机排气中的CO,HC,NOx在所有的工况下均有明显的净化效果,在中等负荷工况下对烟度有较好的净化效果。

At present, the quantity of various diesel vehicles has been increasing each year in our country, which has caused serious environmental problems. In order to meet the strict regulations on emission, an integrated purification device which can purify the exhaust comprehensively is presented in this paper. Experiment results show that this installation not only can clearly reduce HC, CO and NOx emission during the different working conditions, but also has a good purification effect on smoke in medium loading condition.
