Description

  This device is a black smoke emitted from a diesel vehicle and an instantaneous combustion purification device. In particular, the present invention relates to a device for treating black smoke emitted from a diesel vehicle and a flash combustion purification device for cleaning an exhaust pipe filtration system of a diesel engine to keep the exhaust gas smooth.

  When the exhaust gas discharged from the diesel vehicle engine passes through the filtration system, carbon accumulates on the filter of the filtration system.

  When the deposited carbon reaches a certain thickness, the filter, that is, the pressure in the exhaust pipe (back pressure) increases.

  Therefore, conventionally, in the automobile industry, a back pressure sensor is provided in an exhaust pipe of an engine of a diesel vehicle to detect a pressure value of a filter of a filtration system to detect a carbon deposition state and a filter clogging condition.

  When the exhaust gas discharged from the diesel vehicle engine passes through the filter of the filtration system and the carbon deposited becomes a certain thickness, the exhaust gas is clogged, and an increase in the exhaust back pressure is detected.

  The engine management system emits a signal to raise the working temperature of the engine to burn off carbon deposited on the filter surface of the filtration system and remove the filter clog.

  However, the environment in which the vehicle is used is not preferable (such as in Taiwan's cities), and it can stop while driving, or stop repeatedly while driving, or in the driver's habits (for short distances) When traveling at a relatively slow speed (running or traveling on a highway), the diesel vehicle provided with the filtration system has a low engine rotation speed and cannot increase the engine operating temperature.

  Therefore, since carbon deposited on the filter surface of the filtration system cannot be burned and removed, it not only affects the filtration of exhaust gas discharged from the diesel engine, but also affects the normal operation of the diesel engine.

  When the above situation occurs, the vehicle can only be driven to the car service station and the technicians must burn and remove the carbon deposited on the filter surface of the filtration system.

  This consumes time and money, is uneconomical and very troublesome.

  An object of the present invention is to provide a device for treating black smoke emitted from a diesel vehicle that can remove carbon deposited on a filter of a filtration system and an instantaneous combustion purification device.
