Benefits of technology

[0006]The primary object of the present invention is to provide an exhaust purification device for vehicles, which can solve the

Problems solved by technology

After the vehicle has been used for a period of time, the accumulated particulate matter or soot can cause the filter to be plugged, thereby increasing the pressure in the exhaust pipe that mounts the filter.
However, since vehicles are often driven at low speeds on city streets, the working temperature of the engines cannot be increased to a level at which a regeneration process can be performed properly.
To remove the accumulated particulate matter, the user has to request a service factory to burn th

Abstract

An exhaust purification device for vehicles comprises a connection unit, a combustion unit, a buffer unit, a filtration unit, an emission unit, and a control unit. The connection unit is adapted to be connected to an exhaust pipe of a vehicle's engine. The combustion unit includes a main housing, a fuel-atomization nozzle, and an igniter. The nozzle and the igniter are arranged in an open-end container. The nozzle is connected to a fuel tank. An air pump is connected to the open-end container. The buffer unit is provided with a temperature sensor, an exhaust-buffering mask, and a fan. The filtration unit can remove the soot contained in the exhaust gas. The emission unit includes an L-shaped porous tail pipe being sealed with a porous cover. The control unit is electrically connected with the igniter, the fuel pump, the air pump, and the temperature sensor for controlling their operations.

Description

TECHNICAL FIELD OF THE INVENTION[0001]The present invention relates to an exhaust purification device that can be mounted to an exhaust pipe of a vehicle's engine to allow the accumulated soot to be quickly removed, so that the exhaust gas can be expelled more smoothlyDESCRIPTION OF THE PRIOR ART[0002]For a diesel-engine vehicle, as the exhaust gas flow through a filter, the particulate matter or shoot contained in the exhaust gas can accumulate at the filter. After the vehicle has been used for a period of time, the accumulated particulate matter or soot can cause the filter to be plugged, thereby increasing the pressure in the exhaust pipe that mounts the filter. To solve the problem, the automobile industry employed a pressure sensor that can be installed in the exhaust pipe to detect the pneumatic pressure therein, so that the plugged condition of the filter can be obtained. With the pressure sensor detecting a high pressure, an engine management system of the vehicle can know t...
