Inlet manifolds

Description 1072B

1.9 JTD 8v

Operation

The air chamber is made from aluminium and receives pressurized air, cooled by the intercooler (on the 115 cv version only), and conveys it directly to the cylinder head.

A throttle body fitted to the air chamber intake is controlled by the injection control unit.

In order to limit engine shake during switching off, the injection control unit controls the closure of the throttle, while the throttle remains open under all other service condtiions.

The spiral inlet manifolds give the air the necessary (swirl) rotary motion for correct combustion.

An excess pressure sensor Characteristic of working principle 1060G pressure pump electric controlconnected to the injection control unit, is fitted on the chamber.
