Variable geometry intake
Function
Extend or shorten the engine intake ducts to in-
crease the intake air quantity according to the
engine revs.
Operation / Operating principle
The system consists of:
•
two intake ducts for each manifold,
which may be joined (long ducts) or
separated (short ducts);
•
a motor that, by means of an endless
screw, activates the upper part of the
intake ducts;
•
a variable geometry control unit for
managing the system, interfaced with
the engine injection control unit.
At key-ON, the variable geometry control unit low-
ers the ducts (if still in the raised position). Subse-
quently, depending on the control voltage on PIN
2 from the injection ECU (0V down, 5V up), the
ECU drives the electric motor with the relative po-
larity for raising or lowering the ducts. The drive
voltage delivered to the motor is determined in re-
lation to battery voltage and the motor is stopped
once a given current limit is reached or if the time-
out period of 500 ms has elapsed.
