What is the maximum temperature of a car engine?

[MacLandon]

Engine operating temperatures typically range between 85-110°C, exceeding which is considered overheating. German cars, whether turbocharged or naturally aspirated, generally operate at higher temperatures than Japanese cars. The design philosophies of German and Japanese manufacturers differ, resulting in distinct engine characteristics. On average, German naturally aspirated engines run 5-8°C hotter than their Japanese counterparts. Below are detailed explanations: 1. Detail 1: The combustion temperatures inside gasoline and diesel engines reach approximately 2500°C and 2000°C respectively. 2. Detail 2: Operating temperatures vary slightly among different automotive brands. Turbocharged engines consistently operate at higher temperatures than naturally aspirated ones, while German naturally aspirated engines maintain higher average working temperatures than Japanese naturally aspirated models.
