Embodiment Construction

[0024] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0025] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "front", "rear", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description. It is not intended to indicate or imply that the referred device or element must have a particular orientation, be constructed in a particular orientation, and operate in a particular orientation, and thus should not be construed as limiting the invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and should not be construed as indicating or implying relative importance.

[0026] Such as figure 1 As shown, a particle trap includes a first cylinder body 1 and a secon...

Abstract

The invention relates to the field of car exhaust gas treatment, in particular to a particulate filter and a car. The particulate filter comprises a first barrel body and a second barrel body, and therear end of the first barrel body communicates with the front end of the second barrel body. The first barrel body is internally provided with an oxidation catalyst, the barrel wall of the first barrel body is provided with a first temperature sensor and a second temperature sensor, wherein the first temperature sensor and the second temperature sensor are separately located on the front and rearends of the oxidation catalyst. The second barrel body is internally provided with a particle catching collecting catalyst, and a differential pressure transducer is arranged between the front and rear side barrel walls of the particle catching collecting catalyst. The invention further discloses a car, and the car comprises the particulate filter. The particulate filter and the car have the advantages that the particulate filter is relatively simple and compact in structure, the sensors are arranged simply, the cost is low, the disassembling is convenient, and the maintenance cost is low.

Description

technical field [0001] The invention relates to the field of automobile tail gas treatment, in particular to a particle trap and an automobile. Background technique [0002] With the rapid development of the economy and the continuous improvement of people's living standards, the number of automobiles has increased year by year, followed by increasingly serious environmental pollution. Therefore, the control of automobile exhaust pollution is imminent. The particle filter is an installation The filter in the engine exhaust system can capture the particulate matter before it enters the atmosphere. The particulate filter can effectively reduce the emission of particulate matter. It first captures the particulate matter in the exhaust gas, and then traps it Oxidizes the particles and regenerates the particle trap. The so-called filter regeneration means that during long-term work, the gradual increase of particulate matter in the trap will cause the engine back pressure to inc...
