After the manual gear runs hot, the engine exhaust gear suddenly becomes larger, and the 1500 rotation speed cannot be reduced. What happened?

This is normal, that is, you drive a Ferrari, and after several hours of high engine speed, the temperature of the engine, the temperature of the oil and the temperature of the coolant are very high, and suddenly the engine stops exploding, and there is no intake air brought by your high-speed driving for high-speed cooling. It is not enough to rely solely on the engine fan, but don't worry, it will basically return to normal after 20 minutes of low speed.

The ignition and gas distribution system of the engine is constantly adjusted according to the temperature of the engine. For example, in hot summer, when the outdoor temperature is close to 40 degrees, you will also have this situation after traffic jams or long-term exercise. You can check the cooling system.
