Is there less steam in the exhaust pipe and short service life of the three-way catalyst?
2. There is more or less water vapor in the exhaust gas, which can only explain the reference for judging whether the combustion is sufficient or not and the reference for the engine working condition. It is not directly related to the service life of the three-way catalytic purification device.
For example, there are many reasons for incomplete combustion: ignition part (fire, electric leakage, weak ignition intensity, etc. ), the formation and accumulation of carbon deposits (such as improper engine maintenance, or overdue vehicle maintenance, resulting in oil deterioration or excessive viscosity ...), injector failure, oil circuit blockage, foreign matter and other reasons may cause incomplete combustion.
3. The three-way catalytic device plays an important role in reducing the pollutants produced by emission. When used together with oxygen sensor, it plays an important role in reducing fuel consumption and improving automobile economic performance to a certain extent.
For example: the engine is not working normally, the emission is not up to standard, and the combustion is not sufficient. The oxygen sensor will feed back the collected relevant signals to the ECU, prompting the owner to repair or maintain the vehicle. At the same time, under such working conditions, it will undoubtedly bring a certain "burden" to the purification device and affect its service life. Especially for car owners who have not maintained their vehicles in time, the service life of three-way catalysis will be greatly reduced. So it is very important to pay attention to maintenance at ordinary times. In addition, the choice of fuel is also one of the key factors affecting its service life.
