What is iat temperature?

IAT (Intake Air Temperature) is a measurement of the temperature of the air entering the engine during combustion in an internal combustion engine. IAT measurements are typically made using a sensor located in the air intake system of the engine. The temperature of the air entering the engine has a significant impact on the performance and efficiency of the engine. Cooler air is denser and has a higher oxygen content, resulting in better combustion and improved engine performance. Warmer air is less dense and has a lower oxygen content, resulting in decreased performance and efficiency. The IAT sensor helps the engine management system to adjust the air-fuel ratio and ignition timing based on the temperature of the air entering the engine. This helps to optimize engine performance and fuel efficiency in various environmental conditions.
