INTAKE AIR DISTRIBUTION AND FILTERING

Diesel Engines

Air Cleaner Assembly:

The intake air system consists of the following components:
- engine air cleaner
- air cleaner element
- mass air flow (MAF) sensor
- air cleaner outlet tube
- engine charge air cooler
- charge air cooler ducts

The engine air cleaner contains an air cleaner element made of treated, pleated paper, a new air cleaner element must be installed periodically as scheduled. Engine performance and fuel economy are adversely affected when maximum restriction of the air cleaner element is reached. The charge air cooler subsystem cools and increases the density of the compressed turbocharger air.
