Intake Air Systems: Overview: Notes

The intake air system provides clean air to the engine, and optimizes airflow. The intake air system consists of an air cleaner assembly, turbocharger assembly, charge air cooler (CAC) and hoses. The intake air system also contains the mass airflow (MAF), intake air temperature (IAT), charge air cooler temperature (CACT) and manifold absolute pressure (MAP) sensors. For additional information on the intake air system components, refer to ENGINE CONTROL COMPONENTS .

The filtered air enters the turbocharger assembly where it is heated and compressed. The heated compressed air enters the CAC system where it is cooled and then routed into the intake manifold for distribution into the combustion chambers.
