Air Filter Element: Description and Operation
Intake Air System
Dirt and dust particles in the air are abrasive and, if allowed to enter the engine with the intake air, can cause significant damage in a relatively short
period of time. The air cleaner assembly contains a paper filter element that removes these particles from the intake air.
Two resonance chambers are connected to the intake air ducts. Chamber #1 is a silencer connected ahead of the air cleaner to reduce intake noise.
Chamber #2 increases the volume of the intake system between the air cleaner and throttle body. This helps take advantage of harmonic oscillations
within the intake system to improve volumetric efficiency at low engine speeds, and increase low speed torque.
Other intake system components include the throttle body, bypass air control valve, air hoses, and ducts. These components are listed separately in this
section.
