Knowledge of the owner of the family car we mentioned in previous articles, there has recently been to this site reflect his new owners bought the car appeared frustrated and lack of motivation and so on. Car owners suspected quality problems, then to the 4S shop inspection, the answer is surprisingly uniform: Because oil problems caused the oxygen sensor and catalytic converter damage.
Faced with this situation, in addition to condemning the gas station owners, what else can make their own oxygen sensors and catalytic converters become more longevity it?
I believe we oxygen sensors and catalytic converters should have a certain understanding. Although they are two different parts, but they have a common purpose: to reduce the hydrogen compound (HC), carbon monoxide (CO) and nitrogen oxides (NOX) into the air in these three pollutants; difference is oxygen before effect sensor is to reduce these harmful pollution generated, and the role of catalytic converters is to these pollutants by oxidation and reduction into harmless carbon dioxide, water and nitrogen, is a purification device.
In our visits to the 4S shop sales department found that the oxygen sensor and catalytic converters are of durable products, under normal circumstances is not so easily broken, but usually do not require special maintenance. As long as the daily lives of some more attention to detail, you can largely prolong their life. So, I have mentioned some of the following suggestions are simple precautions.
First, how to get the oxygen sensor longer life?
1 checked once every 30,000 km
Every 30,000 km check the working status of the oxygen sensor, if aging or failure of timely cleaning or replacement of the oxygen sensor. Because, catalytic devices and engine performance will be as a result of the oxygen sensor malfunction and damage, do not lose the greater.
2 Do not let the oxygen sensor with a hard object collision
Because the oxygen sensor has a ceramic sensing element, if dropped on the floor or other hard objects collide with this severe vibration, shock, it may damage the ceramic sensor element or heating elements.
3 Avoid pulling the sensor wire
this and other electrical devices, excessive pull sensor wire, it could result in unreliable sensor connection, thus affecting the work of the oxygen sensor.
4 Do not wash the exhaust pipe after flameout
just turn off the engine; be sure not to go immediately rinse the exhaust pipe. Because the exhaust pipe when subjected to external rapid cooling will cause the ceramic sensing element oxygen sensor burst, causing the oxygen sensor damage.
Second, how to make catalytic converters last longer?
1 not a small gas station
As mentioned earlier, the oil issue is the biggest cause of the oxygen sensor and catalytic converter damage. So, everyday car owners to avoid irregular gas stations as possible. If the addition was completed at a gas station, the vehicle appeared frustrated or insufficient power failure, must be timely to the 4S shop to clean and replace the gas station.
2 Avoid prolonged idling
When idling idling, there will be a small amount of the mixture has not been completely burned directly into the exhaust system of the engine, if the idle time is too long will cause the exhaust system continues to heat up, thus burn catalytic converters. Therefore, to minimize the vehicle to idle for a long time. To check on a regular basis while the catalytic converter (but it must be operable at temperatures down after!), If there is high temperature and abnormal traces of burnt blazing color, indicating that catalytic converters had overheated, the effect of the work has been reduced.
3-way catalytic converter careful not to underpinning
This is because the manufacturing catalytic converter material is very fragile, the collision will encounter broken, causing catalytic converters and exhaust system blockage, so the vehicle to pay special attention to the car backing. To check on a regular basis while the catalytic converter (but it must be operable at temperatures down after!), See the appearance there is no damage, after the catalytic converter temperature can be lowered by hand percussion metal surface or driving, if the listening There are similar to the sound of broken ceramics, indicating that catalytic converters have been damaged and need to be replaced.
Conclusion: Under normal circumstances the car, oxygen sensors and catalytic converters are not so easily broken, the owner usually pay more attention to some of the details will be able to extend the life of a good. In addition, if car owners find themselves frustrated and appeared underpowered and other issues, we must promptly to the 4S shop to clean the oil and replace the gas station.
