Image recognition based three-way catalytic converter cleaning system with controllable cleaning dosage

Abstract

The invention discloses an image recognition based three-way catalytic converter cleaning system with a controllable cleaning dosage and belongs to the field of automobile detection and repair. The three-way catalytic converter cleaning system comprises an image acquisition and blowdown air-drying integrated device and a cleaning device, wherein the image acquisition and blowdown air-drying integrated device comprises a snake-shaped endoscope as well as an image processing unit, an air pump and a hose which are arranged in a computer; the cleaning device comprises an air pump I, hoses I, a spray pipe, a water pump and a spray nozzle. The three-way catalytic converter cleaning system can solve the current problems about three-way catalytic converter cleaning and can clean the three-way catalytic converter without disassembly of an engine; the pollution degree of the three-way catalytic converter is determined through analysis processing of acquired images, the dosage of a cleaning agent can be controlled effectively, the environment is protected, and the cleaning quality is improved; complete cleaning can be realized with adoption of the image acquisition and blowdown air-drying integrated device, and a user can observe the cleaning effect directly.

Description

Technical field [0001] The invention belongs to the field of automobile detection and maintenance, and particularly relates to a three-way catalytic converter cleaning system with a controllable cleaning amount based on image recognition. Background technique [0002] The clogging of the three-way catalytic converter will make the exhaust of the car exhaust unsmooth, and the exhaust back pressure will increase, which in turn will cause the car's power to drop and fuel consumption to increase. The three-way catalytic converter of high-end brand cars is more expensive, so it is often used to clean the three-way catalytic converter instead of replacing it to solve the clogging problem. [0003] In the early days, the idle speed cleaning method was used to clean the three-way catalytic converter. If the car fails or the three-way catalytic converter is seriously blocked, the vehicle cannot be started and the cleaning cannot be performed. At the same time, this method has very high fuel...

AI Technical Summary

Problems solved by technology

[0002] The blockage of the three-way catalytic converter will make the exhaust gas of the car not exhausted smoothly, and the exhaust back pressure will increase, which will lead to the decrease of vehicle power and increase of fuel consumption.

[0003] In the early days, the idling cleaning method was used to clean the three-way catalytic converter. If the car breaks down or the three-way catalytic converter is seriously blocked, the vehicle cannot be started, and the cleaning work cannot be carried out. At the same time, this method consumes a lot of fuel.

At present, most 4S stores are cleaned by hanging bottles. This method cannot determine the amount of cleaning agent used, and the cleaning time is long, which leads to waste of cleaning agent and environmental pollution. At the same time, users cannot intuitively determine the cleaning effect.
