Auto repair Shop asked me to clean the three-way catalytic converter, Wash Or Not ?

Let your repair shop business be hot: the secret inside the three-way catalyst!


I am often asked: The auto repair shop asked me to clean the three-way catalyst, Should I wash?

Because I don't know what condition his car is, it's really hard to answer. Washing must be spent, if do not wash, any sequelae? 

Take a look at the following. three-way catalytic converter cleaning machine

1. The temperature is too high


At room temperature, the three-way catalytic converter does not have catalytic ability. The catalyst must be heated to a certain temperature to have the ability to oxidize or reduce. Generally, the catalytic converter has a light-off temperature of 250-350 ° C, and the normal working temperature is generally 400-800 ° C. . When the catalytic converter works, the higher the self-quantity, the higher the oxidation temperature. When the temperature exceeds 1000 °C, the catalyst of the inner coating will be sintered and necrotic, and the vehicle spontaneous combustion accident is also prone to occur. Therefore, it is necessary to pay attention to controlling various factors that cause the exhaust gas temperature to rise, such as too late ignition timing or disordered ignition sequence, misfire, etc., which will cause the unburned mixture to enter the catalytic reactor, causing the exhaust gas temperature to be too high, affecting Catalytic converter performance. three-way catalytic converter cleaning machine

2. Chronic poisoning


The catalyst is very sensitive to elements such as sulfur, lead, phosphorus, zinc, etc. Sulfur and lead are derived from gasoline, and phosphorus and zinc are derived from lubricating oil. These four substances and their combustion in the engine form oxide particles which are easily adsorbed on the catalyst. The surface prevents the catalyst from coming into contact with the exhaust gas, thereby losing the catalytic effect, the so-called "poisoning" phenomenon.three-way catalytic converter cleaning machine

3. Carbon deposit blockage


When the car is working at a low temperature for a long time, the three-way catalytic converter cannot be started, and the soot discharged from the engine will adhere to the surface of the catalyst, causing it to be incapable of contacting with CO and HC, and some cars love to burn engine oil, and carbon deposit is getting more and more More, in the long run, the pores of the carrier are blocked, affecting its conversion efficiency.three-way catalytic converter cleaning machine

4. Damage caused by the external environment


The inside of the three-way catalyst is composed of a honeycomb ceramic and a catalyst, and it is easy to damage the three-way catalyst if the bottom is accidentally formed during the formation.three-way catalytic converter cleaning machine
