How long does it take for the engine to cool down after shutting off?

[MacVivian]

It takes about half an hour for the engine to cool down after shutting off. Here are some specific details about engine shutdown: 1. The normal operating temperature of an engine is generally maintained at around 90℃. After parking and shutting off, the engine temperature doesn't drop immediately. As residual heat accumulates, it can easily damage plastic components and wiring harnesses inside the engine compartment, and in severe cases, may even cause vehicle self-ignition. 2. When the output torque is less than the load torque, the engine is braked and cannot perform the four-stroke cycle operation. If the braking time is too long, with no output torque and the loss of motion inertia, the engine will shut down. 3. Incorrect operation methods can also cause the engine to shut down.
