In recent years, owners of cars have been frustrated and lack of motivation. The owner suspected that it was the quality of the car, and then went to the 4S store to get the answers surprisingly unified: the oil problem caused oxygen sensors and three yuan catalyst to be damaged.

In the face of this situation, in addition to condemning the gas station, owners themselves have ways to make oxygen sensors and three way catalytic converters become longer life.

Through the previous articles, I believe you should have a certain understanding of oxygen sensors and three way catalytic converters. Although they are two different parts, they have a common purpose: reducing the hydrogen compounds (HC), carbon monoxide (CO) and nitrogen oxides (NOX), the three pollutants in the air; the difference is that the role of the pre oxygen sensor is to reduce these harmful pollution, and the role of the three element catalyst is to remove these pollutants. The body is transformed into harmless carbon dioxide, water and nitrogen through oxidation and reduction. It is a purification device.

In our visit to the 4S after sales department, we found that oxygen sensors and three yuan catalytic converters are all durable products. In general, it is not so easy to be bad, and usually do not need special maintenance. As long as we pay more attention to details in daily life, we can extend their life to a large extent. Therefore, some of the suggestions I mentioned below are simple points for attention.

1. How to make the oxygen sensor life longer?

1. every 30 thousand km checks

Check the working status of the oxygen sensor every 30 thousand km. If aging or failure occurs, clean or replace the new oxygen sensor in time. Because the performance of the three way catalytic converter and engine will be damaged due to the abnormal operation of the oxygen sensor.

2. do not let oxygen sensors collide with hard objects

Because oxygen sensors have ceramic sensing elements, if they fall on the ground or collide with other hard objects, this intense shock and shock may damage the ceramic components or heating elements in the sensor.

3. avoid pulling sensor wire

As with other electrical equipment, excessive pulling of sensor wires may lead to unreliable connection of sensors, thus affecting the work of oxygen sensors.

Do not flush exhaust pipe after 4. flameout

Do not flush the exhaust pipe immediately after the engine has stalled. Because the exhaust pipe is sharply cooled externally, it will cause the ceramic sensor of oxygen sensor to burst, resulting in damage to the oxygen sensor.

Two. How to make the three - element catalyst life longer?

1. do not go to a small gas station to refuel

As mentioned earlier, the oil problem is the biggest cause of damage to oxygen sensors and three way catalytic converters. So, in the daily car, owners can avoid refueling at irregular gas stations as far as possible. If there is a setback or lack of power when a gas station is finished, it is necessary to clean the 4S shop in time and replace the gas station in time.

2. avoid long time idle

At idle idle, a small amount of mixed gas in the engine will not be completely burned and directly into the exhaust system. If the idle time is too long, the exhaust system will continue to heat up and burn the three element catalyst. So, car owners should try to reduce the long idle time as much as possible. At the same time, check three yuan catalyst regularly (but it must be operated after the temperature drops!). If there is a high temperature burning trace and abnormal color, the catalyst has been overheated and the work effect has been reduced.

3. three yuan catalyst should not take care of the bottom

This is because the material that makes the three element catalyst is very fragile, and the collision will break up, which leads to the blockage of the catalyst and the exhaust system, so the car pays special attention to the bottom of the car. At the same time, check the three yuan catalyst regularly (but must be operated after the temperature drops!). See if there is any damage on the surface. After the temperature drop of the three element catalyst, it can be used to knock on the metal surface or to drive. If there is a sound like ceramic broken inside, the catalyst has been damaged and needs to be replaced.

Conclusion: in normal vehicle conditions, oxygen sensors and three - element catalytic converters are not so easy to be bad. The car owners pay more attention to the details and can prolong their life. In addition, if the owner finds that he or she has problems such as setbacks and lack of motivation, it is necessary to clean the oil circuit and replace the gas station in 4S shop.
