Can a Naturally Aspirated Car Be Shut Down Directly After a Long Trip?

[DelAustin]

Naturally aspirated cars can be shut down directly after a long trip. Related introduction: 1. Overview: The so-called natural aspiration refers to a form where atmospheric pressure forces air into the combustion chamber without the use of any supercharger. In simpler terms, when the car is operating, its intake pipe acts like a vacuum tube, with air pressure being forced into the intake manifold by atmospheric pressure, similar to "inhaling" during normal breathing. 2. Principle: Even if a naturally aspirated engine is turned off immediately after high load, the electronic water pump will still be triggered to cool the engine. The coolant will continue to circulate within the engine water jacket for about 15 minutes until the ECU detects that the temperature has reached the desired level and automatically shuts off. Therefore, overheating issues generally do not occur.
