With the rapid development of the automobile industry, the rapid growth of the number of cars has brought many conveniences to our lives, but also accelerated the speed of air pollution. In some cities with high car ownership, vehicle emission pollution has become an important cause of air pollution.

Three-way catalytic converter refers to the conversion of harmful gases such as CO, HC and NOx into harmless carbon dioxide, water and nitrogen gas through oxidation and reduction.It is the most important external purification device installed in the automobile exhaust system. With the three-way catalyst, exhaust emission can meet the standard.

Due to the driver's bad driving habits, or long-term driving in congested roads, the engine is often in incomplete combustion state, which will form coke in the oxygen sensor and three-way catalyst.

In addition, with the emission of exhaust gases, these dirt will also be deposited on the surface of the oxygen sensor and the three-way catalyst. It is due to many factors, making the car in a mileage, in addition to the intake valve and combustion chamber produce carbon, will cause oxygen sensor and three catalytic poisoning failure, three catalytic blockage and EGR valve sediment blockage and other faults, resulting in abnormal engine work, resulting in increased fuel consumption, power decline and excessive exhaust gases and other issues.

When the blockage occurs, the car will appear poor exhaust problems, and the oxygen sensor will also be affected can not work properly, which will lead to the engine power decline, refueling weakness, increased fuel consumption.Therefore, the three catalytic damage, the impact on the engine is still very large, must be repaired in a timely manner, if it is just blocked clean up, if it is failure or broken, it must be replaced.

Regular cleaning of three catalytic converter, cleaning throttle position, cleaning together with three, if in order to save costs, please regularly clean the three catalytic converter, theoretically suggested that ten thousand kilometers cleaning once, but according to the use of the environment and habits, the owner can flexibly master the cleaning rhythm, such as found after cleaning carbon and insufficient power, can consider cleaning three! If you do not install it, the engine can not receive the correct exhaust signal, there will be a control failure, the car will accelerate weak, fuel consumption increased fault, engine fault light will light up. So usually can not ignore the three catalytic converter problems, there are problems in a timely manner, pay attention to driving safety.
