Is it necessary to turn off the engine when parked for three to four minutes?

[DiTeagan]

It is advisable to turn off the engine when parked for more than three to four minutes. Reason one for turning off the engine when parked: After driving for a period of time, the engine components become very hot. If the engine is not turned off, parts such as the cylinders and piston rings, crankshaft and connecting rods may stick together due to the high temperature, leading to a phenomenon known as 'seizing' or 'bearing failure' upon the next startup. Reason two for turning off the engine when parked: After prolonged operation, it is best to let the car idle for a few minutes before turning off the engine, allowing the engine temperature to decrease naturally. The vehicle has an automatic cooling function, meaning that if the engine temperature is too high after parking, the fan will automatically turn on to continue cooling the engine until it reaches a reasonable temperature, at which point the fan will stop automatically.
