Problems solved by technology

In actual use, due to urban road congestion, poor fuel oil quality, and large dust in the air, the blockage of the three-way catalytic converter has become a very common problem.
The blockage of the three-way catalytic converter not only causes a serious increase in the fuel consumption of the vehicle, but also increases the exhaust back pressure, which will also cause the brake vacuum booster pump to fail to draw vacuum sufficiently, resulting in the brake pedal not being able to be stepped on or malfunctioning, the power of the car is reduced, and the exhaust gas exceeds the standard.
It even causes the exhaust pipe to burn red, causing the vehicle engine to pull cylinders or the vehicle to spontaneously ignite
For a long time, auto repair factories have neither effective prevention measures nor effective treatment methods for the clogging of three-way catalytic converters. The only way to replace the clogged three-way catalytic converters is to waste resources and increase the cost of vehicles. user's burden

Embodiment Construction

[0017] Below in conjunction with the accompanying drawings and examples, the specific implementation of the present invention will be further described in detail, the following examples are used to illustrate the present invention, but not to limit the scope of the present invention.

[0018] When cleaning, loosen the fixing bolt at the outlet of the three-way catalytic converter, move the muffler exhaust pipe assembly backward, and separate the three-way catalytic converter from the muffler exhaust pipe assembly. Remove the front oxygen sensor at the inlet of the three-way catalytic converter.

[0019] Such as Figure 1-2 Shown is a cleaning device for a three-way catalytic converter, including a box body 7, which is respectively provided with a liquid feeding assembly 1 for adding cleaning liquid to the three-way catalytic converter; a circulating cleaning assembly 2 for cleaning the three-way catalytic converter. The three-way catalytic converter is cyclically cleaned; the...

According to the adopted technical scheme, the device comprises a tank, wherein a liquid adding assembly, a cyclic cleaning assembly, a liquid discharging assembly and an automatic control system are arranged in the tank; the liquid adding assembly is used for adding a cleaning liquid into a three-way catalyst; the cyclic cleaning assembly is used for cyclically cleaning the three-way catalyst; the liquid discharging assembly is used for discharging a waste liquid generated after the cleaning from the three-way catalyst; the liquid adding assembly, the cyclic cleaning assembly and the liquid discharging assembly are all connected with the automatic control system; and the automatic control system is used for automatically controlling the whole cleaning process. The device provided by the invention has the characteristics that the disassembly is not needed, the operation is convenient and the running is safe.

Description

technical field [0001] The invention relates to the automobile maintenance industry, and in particular discloses a cleaning device for a three-way catalytic converter. Background technique [0002] The three-way catalytic converter is the most important external purification device installed in the automobile exhaust system. It is installed between the exhaust outlet of the automobile engine and the muffler. It can convert the harmful gas discharged from the automobile engine into a harmless gas. The carrier part of the three-way catalytic converter is a porous honeycomb ceramic material, and its surface is covered with a layer of precious metals such as platinum, rhodium, and palladium, which can change hydrocarbons and carbon monoxide in the exhaust gas into water and carbon dioxide, and at the same time change nitrogen oxides into water. for nitrogen and oxygen. In actual use, due to urban road congestion, poor fuel oil quality, and large dust in the air, the blockage of...
