What is the normal temperature for a car engine?

[DiEvelyn]

The following is the normal temperature range for a car engine: The normal operating temperature of a car engine is generally between 80°C and 90°C, while some high-performance engines may operate at temperatures above 90°C to 100°C. Below is relevant information about car engine temperature: 1. When the temperature is too high: When the engine temperature is too high, the temperature of the air entering the engine is also higher, resulting in a reduced actual air intake. This decreases the engine's volumetric efficiency, leading to a drop in power and torque, manifesting as insufficient engine power. 2. When the temperature is too low: If the temperature of the air-fuel mixture (or air) entering the cylinders is too low, the quality of the combustible mixture deteriorates, making ignition difficult or combustion slow. This results in reduced engine power, increased fuel consumption, and significantly higher emissions of harmful gases.
