9. Precautions

When calculating the purification rate, it is important to ensure accurate measurement of the initial pollutant concentration (ME1) and the purified pollutant concentration (ME2). Any small error may affect the final calculation result. At the same time, factors such as the working time, types of pollutants, and environmental conditions of the purification system also need to be considered, which will have an impact on the purification effect.

If there is mechanical damage and thermal sintering phenomenon in the ternary catalyst, and the vehicle mileage exceeds 200000 kilometers, it may affect its purification effect.

If the three-way catalyst experiences a "poisoning" phenomenon, simple cleaning often cannot solve the problem.

During the engine cleaning process, if the engine stalls, immediately disconnect the connecting hose between the engine and the cleaning equipment, and close the flow valve. Restart the engine and ensure smooth idle before reconnecting and adjusting the cleaning equipment.

At the same time, it is necessary to check whether the concentration of the mixture is appropriate to ensure that the cleaning liquid can be smoothly inhaled into the intake duct in a mist form.

In addition, cleaning the three-way catalyst should be carried out after cleaning the throttle valve, fuel injector, and combustion chamber. During the cleaning process, the idle speed should be kept stable to avoid damage to the three-way catalyst due to overheating. Special care should be taken to ensure that the cleaning fluid does not drip onto the vehicle's paint surface. Finally, the work area should be kept away from sources of fire and appropriate fire safety measures should be taken.

1. During the cleaning process, pungent gases such as hydrogen sulfide and sulfur dioxide will be emitted, which is the result of the reaction between the cleaning agent and carbon deposits.

2. After cleaning, the emission of nitrogen oxides will significantly decrease, indicating a significant cleaning effect.

Cleaning effect:

The ternary cleaning agent can comprehensively clean the intake system, combustion system, and exhaust system of the engine. It can effectively, quickly, and efficiently remove gum carbon deposits in the intake duct and combustion chamber, as well as chemical complexes on the oxygen sensor and three-way catalyst. During the cleaning process, these carbon deposits and complexes will be fully oxidized and burned into gases, significantly reducing the emissions of CO, HC, and NOx in the exhaust.

Maintenance effect:

After cleaning, harmful substances such as CO, HC, and NOx in the exhaust emissions of cars will be significantly reduced, which is beneficial for environmental protection and the long-term use of cars.

The three-way catalytic converter, especially its NO emissions, significantly decreased after cleaning. In addition, cleaning can improve the atomization effect of fuel, enhance combustion efficiency, thereby reducing fuel consumption and achieving 5-20% fuel savings. At the same time, it can enhance low-temperature cold start capability, reduce noise, and improve power performance. In the long run, this can not only extend the service life of the engine and three-way catalyst, but also ensure the daily maintenance of the vehicle. It is recommended to perform a non disassembly cleaning of the three-way catalyst every 20000 to 30000 kilometers or once a year.
