What is the maximum temperature an engine should not exceed?

[VonHarmony]

Car engines should not exceed a normal operating temperature of 105 degrees Celsius. The normal operating temperature range for an engine is between 85-105 degrees Celsius, referring to the internal temperature of the engine. Below 85 degrees, gasoline atomization is poor, lubricating oil flow is inadequate, the engine is prone to wear, and performance is suboptimal. Exceeding 105 degrees can cause the engine to overheat. Intake temperature at full throttle: Generally, under maximum load conditions (full throttle), the intake temperature of a car engine ranges between 0 to 80 degrees Celsius. Intake temperature of turbocharged engines in summer: For turbocharged engines, summer conditions can result in intake temperatures reaching 80 degrees Celsius. During the compression stroke, this temperature can rise to 500-600 degrees Celsius. Local temperatures during compression: Heat is released to the cylinder walls during compression. After ignition, local peak temperatures can reach 2000 degrees Celsius or higher. The average exhaust temperature typically ranges between 800 to 1000 degrees Celsius.
