Why the naturally aspirated engine should not be turned off immediately after a trip

Many car owners know that a turbocharged engine cannot be turned off immediately after a trip and without dropping the speed to idle. But almost no one thinks that this rule also applies to atmospheric engines!

The fact is, emphasize the mechanics of the federal service for emergency technical assistance on the roads "RussianAvtoMotoClub", that when the engine is abruptly turned off, the water pump also stops working. And this leads to the fact that the engine parts stop cooling. As a result, they overheat and soot appears in the combustion chambers. All this negatively affects the motor resource.

In addition, immediately after the ignition is turned off, the relay-regulator is turned off, but the generator, which is driven by the shaft that continues to rotate, continues to supply voltage to the vehicle's on-board network. Which, in turn, can adversely affect the functioning of electronics.

Therefore, do not be lazy, having parked the car near the house, let it “grind” for a couple more minutes - it definitely won’t be worse.
