One, do not use leaded gasoline

Because after the combustion of leaded oil, lead particles with exhaust gas through the three catalytic converter, will be covered on the catalyst surface, the catalyst action area is reduced, thus greatly reducing the conversion efficiency of the catalyst, resulting in lead poisoning of the three catalytic converter.

 Two, should avoid unburned mixture into the catalyst

In the use of the vehicle in the following circumstances will lead to unburned mixture into the catalyst: long time idle idling, engine burning oil, engine water temperature is too high, air filter blockage, fuel nozzle blockage and so on.

 Three, avoid chassis collision

Driving on uneven roads should pay special attention not to "bottom", because the chassis after the collision is easy to make the catalyst failure and exhaust pipe blockage.

 Four, avoid sudden ignition of vehicles in motion

If the vehicle is ignition in the road due to insufficient fuel, it will lead to unburned mixture into the catalytic reactor, resulting in high exhaust temperature, affect the efficiency of the catalytic converter, and damage the three catalytic converter.It is suggested that the vehicle fuel remaining two grid fuel addition.

 Five, appropriate running high speed

Long time idle speed, low speed operation will lead to insufficient combustion of the engine combustion chamber, carbon deposits in the exhaust system, through running high speed can clean up carbon deposits to a certain extent.

 Six, fuel additives should be used carefully

The fuel additives on the market, fuel treasure in most cases is containing silicon, lead and other elements, these elements will cause damage to the three catalytic converter, fuel additives need to be carefully selected.

 Seven, regular inspection of three catalytic converter

Inspection content: exhaust pipe is abnormal, this abnormal sound is usually caused by loose exhaust pipe joint, three catalytic converter damage, catalyst replacement plug loose and other reasons;exhaust pipe cracking or shell pressed such as appearance damage;exhaust tail pipe with no catalyst particles discharged.If the three catalytic converter shell damage or exhaust tail pipe discharge particles, all need to be replaced.

 Eight, three catalytic converter service life

Three catalytic converter is a service life, the general use cycle in the 5 years or 160,000 kilometers or so.If used improperly will lead to three catalytic converter service life cycle shortened.When beyond the service life cycle, it should be replaced in time.
