Title: Exhaust emission control device for vehicle diesel engine
Inventor: WATANABE SHIGEO
IPC: F02B3/06
Filed: 1991-02-18
Abstract: PURPOSE:To reduce a supply electric current to respective electrodes in a range capable of securing target particulate collecting efficiency by arranging a particulate electrifying discharge electrode pair and a particulate collecting collecting electrode pair, and controlling voltage impressed upon these. CONSTITUTION:Exhaust gas discharged from a vehicle diesel engine is introduced to an outer can part 2 from an upstream side gas exhaust pipe 1a. In this case, negative DC high voltage is impressed upon a high voltage electrode part 5 by a high voltage electric power supply part 6, and corona discharge is generated between the high voltage electrode part 5 and the outer can part 2 in discharge space Sd having small clearance d1. A particulate contained in exhaust gas in the discharge space Sd is electrified negatively. On the other hand, since collecting space Sc has large clearance d2, the corona discharge is not generated, so that only an electrostatic field is creased. Thereby, since the electrified particulate flowed into the collecting space Sc is attracted to the electrostatic field and is accumulated on an inside surface of the outer can part 2, clean exhaust gas can be discharged from a downstream side gas exhaust pipe 1b.
