Air intake circuit

AIR INTAKE CIRCUIT

The air intake circuit is made up of various components which direct the necessary flow of air to the engine in the different operating conditions:

• air filter,
• butterfly casing,
• direct current motor, for controlling the engine idle speed,
• inlet manifold.

AIR FILTER

The air filter is the thermostatic type.
The switch to the hot or cold air position takes place by means of a thermostatic valve (5) operated by the vacuum, in turn intercepted by a thermal valve (6).
The valve (5) is activated by the engine vacuum until the thermal valve (6) detects a low temperature for the intake air.
