What effect will the car idle 12 hour have on three-way catalysis?

Stop the car without turning off the engine, that is, keep the engine idling. Many people sometimes like to let the car idle, that is, after the car stops, don't turn off the engine, while listening to songs or playing mobile phones in the car, but do you know? Doing so is unfavorable to the growth of vehicles, which can be said to be harmful! So, what will happen if the car idles for a long time?

First of all, let's popularize what idle speed is. Idle speed is a working state in which the engine keeps the lowest running speed. When the engine is running, if the accelerator pedal is completely released, the engine will be at idle speed. Simply put, generally speaking, idle speed means that the engine is not working hard, the car is still in place, but the engine is still burning oil. The fuel consumption at this time is what we call idle fuel consumption.

Harm of long-term idle state to the engine: When idling, the fuel burns incompletely, which is easy to form carbon deposit, which has a great influence on the engine. First of all, the carbon deposit on the throttle will lead to acceleration delay and unstable idle speed! Piston carbon deposition also affects the volume of combustion chamber, reduces engine power and shortens engine service life.

If the vehicle keeps idling for 12 hours, it will cause a series of problems, first of all, it will damage the three-way catalyst, so it is necessary to do a better inspection at this time, and it will also cause more carbon deposition in the engine combustion chamber.

There's nothing wrong with waiting for someone at idle speed for a short time. However, when idling for a long time, the engine will have problems such as poor heat dissipation (especially in summer), poor emission and easy carbon deposition. In short, it is harmful and useless. Therefore, it is very important to use the vehicle correctly, otherwise it will seriously affect the normal service life of the vehicle.
