What is the normal temperature range for a car?

[HadleyRose]

Here are the normal temperature ranges 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 can 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 excessively high, the intake air temperature also rises, resulting in reduced actual air intake. This decreases the engine's volumetric efficiency, leading to reduced power and torque output, 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 combustible mixture quality deteriorates, making ignition difficult or causing delayed combustion. This results in decreased engine power, increased fuel consumption, and significantly higher emissions of harmful gases.
