Vacuum air circuit

Description 1048A

1.6 16v

The air intake circuit consists of various components which ensure that the air flow required by the engine in the various operating conditions is correctly directed.

1, Inlet manifold

2, Intake air pressure and temperature sensor (See subassembly 1056 PETROL INJECTION SYSTEM)

3, Intake for fuel anti-evaporation system (See subassembly 1080 EXHAUST EMISSION CONTROL SYSTEM)

4, Gas intake from engine crankcase (blow-by) for recirculating exhaust gases at idle speed (See subassembly 1080 EXHAUST EMISSION CONTROL SYSTEM)

5, Intake for brake servo

6, Engine idle speed actuator (See subassembly 1056 PETROL INJECTION SYSTEM)

7, Butterfly casing (See subassembly 1056 PETROL INJECTION SYSTEM)

8, Main gas intake from engine crankcase (See subassembly 1080 EXHAUST EMISSION CONTROL SYSTEM)

9, Air filter

10, Intake vent
