KR950025241A - Particulate matter collection system of diesel vehicle - Google Patents

Abstract

The present invention relates to a particulate matter collecting system of a diesel vehicle, and in order to reduce the particulate matter discharged in the past, the fuel injection timing is delayed, the intake air is throttled, or the exhaust recirculation amount is increased. However, the regeneration of the particulate matter collecting device may not be regulated according to the driving state of the vehicle or the engine state. An object of the present invention is to provide a particulate matter collecting system of a diesel vehicle which enables to control the operation of the particulate matter collecting device according to the engine state. In addition, the present invention is to provide a particulate matter collecting system of a diesel vehicle that can control the operation of the particulate matter collecting device according to the running state of the vehicle, and an object of the present invention is a particulate matter collecting device. Or the driver is recognized by the pressure sensor installed at the end of the exhaust passage. A particulate matter collecting system of a diesel vehicle that can be regenerated by a switch operation of a diesel vehicle is provided. As shown in FIG. 1, the exhaust passage 10 includes a collecting device 12 and a bypass passage (not shown). 14, the main valves 16, 16 'and the bypass valve 17 are attached, and a regeneration device 18 for burning the collected particulate matter is installed in the collecting device 12, and the discharge passage ( 10, an exhaust pressure detecting sensor 19 is provided, and a warning light 20, a regeneration device control means 22, a coolant temperature sensor 24 and an engine speed sensor 26 capable of discriminating the state of the engine E are provided. And the main valves 16, 16 'and the bypass valve 17 according to the signals of the exhaust gas temperature sensor 28, the coolant temperature sensor 24, the engine speed sensor 26, and the exhaust gas temperature sensor 28. ) To selectively pass the exhaust gas through the collecting device 12 or discharge it through the bypass passage 14. It is composed of a collecting device control means 30 to enable the operation of the playback device 18 by the operation of the switch (SW) of the driver as needed, or automatically playback device 18 by the playback device control means 22. It is an invention that can effectively reduce the particulate matter in the exhaust gas is configured to operate the collection device 12 can be operated according to the engine state and the vehicle driving state.

Claims (1)

In the particulate matter collection system of a diesel vehicle, an exhaust passage 10 through which exhaust gas containing particulate matter is discharged is provided with a collecting device 12 and a bypass passage 14 for collecting particulate matter in parallel. 12 and the bypass passage 14 are attached to the front end of the main valve (16, 16 ') and the bypass valve (17), respectively, in the collecting device 12 to burn the collected particulate matter The regeneration device 18 is provided, and the exhaust passage 10 between the engine E and the collecting device 12 has an exhaust pressure capable of detecting the amount of particulate matter collected in the collecting device by the pressure of the exhaust gas. The detection sensor 19 is provided, and the warning light 20 and the exhaust pressure which receive a signal from the exhaust pressure detection sensor 19 and warn the driver to operate the regeneration device 18 when the exhaust pressure is higher than a predetermined value are provided. Collector 12 when above the set exhaust pressure A regeneration device control means 22 and an engine for closing the main valves 16 and 16 'installed at the rear end and opening the bypass valve 17 of the bypass passage 14 so that the regeneration device 18 is operated. E) The main valve 16, 16 'and the bypass valve 17 are opened and closed in accordance with the signals of the coolant temperature sensor 24, the engine speed sensor 26, and the exhaust gas temperature sensor 28, which can determine the state. And collecting device control means 30 to allow the exhaust gas to selectively pass through the collecting device 12 or discharge it through the bypass passage 14. The regeneration device 18 may be operated or the regeneration device 18 may be automatically operated by the regeneration device control means 22, and the collection device 12 may be automatically operated according to the engine state and the vehicle driving state. Particulate matter of the diesel vehicle, characterized in that configured to be Collection system. ※ Note: The disclosure is based on the initial application.
