What is engine cold running-in?

Theoretically, the so-called cold running-in of automobile engine is to install the engine on a special machine tool and use the motor to drive the engine to run in. This kind of running-in is called cold running-in because there is no high temperature heat generated by fuel combustion when the engine works normally. On the contrary, hot running-in usually means that the car is equipped with an engine and burns fuel by ignition.

But now, what we often say about cold running-in is no longer a theoretical explanation. Because people like to look at the literal meaning directly, now people often think that when the car is just started, the engine is driven by the motor, and the operation of the engine has not reached a certain working heat. It can be understood that the running-in of the engine in the "cold" state is called cold running-in. Usually, most automobile parts are worn in the cold running-in stage, so don't drive too hard in the cold running-in stage.

2. Don't drive at high speed. At the beginning of driving, we should control the speed and try not to drive at high speed.

3. Try to avoid overloading in the cold car stage.
