Engine - Intake-Air System - 3.0L (4V): Other Mazda Tribute I рестайлинг

INTAKE AIR DISTRIBUTION AND FILTERING

The air intake system consists of the following

1. air cleaner
2. air cleaner element
3. air cleaner outlet tube
4. inlet tube
5. resonator
6. mass air flow (MAF) sensor
7. throttle body
8. intake manifolds

The intake air system

1. cleans intake air with a replaceable, dry type air cleaner element.
2. measures airflow and air temperature with the MAF sensor.

The throttle body

1. controls air supply to the upper intake manifold by positioning the throttle plate.
2. connects the accelerator cable and, if equipped, cruise control actuator cable to the throttle plate.
3. is not adjustable.
4. cannot be cleaned.
