[LaAmelia]

When driving normally, the optimal temperature range is between 70~90°C. If the temperature exceeds 90 degrees Celsius and remains consistently high, it indicates an abnormal operating condition of the engine. A car engine requires a specific operating temperature for proper functioning—neither too high nor too low is conducive to normal engine operation and performance. Relevant information about car engines is as follows: 1. Introduction: The car engine is the device that provides power to the vehicle, serving as the heart of the car and determining its power, fuel efficiency, stability, and environmental performance. Common gasoline and diesel engines are both types of reciprocating piston internal combustion engines. 2.
