What is the normal temperature range for a car engine?

Under normal circumstances, the normal operating temperature of a car engine ranges between 85-105 degrees Celsius. The normal operating temperatures for an engine are as follows: 1. The normal operating temperature of a car engine is between 85-105 degrees Celsius. 2. Generally, under maximum load (full throttle), the intake air temperature for most car engines ranges between 0 to 80 degrees Celsius. 3. For turbocharged engines, the intake air temperature can reach 80 degrees Celsius in summer. During the compression stroke, the temperature rises continuously to 500-600 degrees Celsius. The compression process involves heat transfer to the cylinder walls. After ignition, localized peak temperatures can reach 2000 degrees Celsius or higher. The average exhaust gas temperature is approximately 800-1000 degrees Celsius.
From my driving experience, the normal operating temperature of a car engine typically fluctuates between 90 and 100 degrees Celsius. This is because the water cooling system is designed to maintain this range, allowing the engine to run efficiently without excessive fuel consumption. The ideal position for the temperature gauge needle on the dashboard is in the middle. If it's too low, say below 80 degrees, the thermostat might be stuck, preventing the engine from warming up properly and leading to higher fuel consumption. If it's too high, exceeding 105 degrees and entering the red zone, it indicates a cooling system issue, such as a faulty fan or low coolant level. Once, during a long trip, I ignored slight overheating, which resulted in a warped cylinder head and a repair bill of 5,000 yuan. So, it's important to keep an eye on the dashboard, especially in summer or during traffic jams. Regularly checking the coolant level and fan operation can save you from major repairs—safety first, after all.
