TECHNICAL INFORMATION
2.15.5 Cold starting device (Heater)
The cold starting device consists of a resistance, managed
by the ECU, which is activated when the ambient temperature
is ≤ -16° C.
The intake air is heated through the resistance and facilitates
starting.
Characteristics:
• Type Hidria AET 12 V
• Power 550 W
2.15.6 Fuel intake regulating valve (SCV)
Valve E is situated on the high-pressure fuel injection pump.
It is managed by ECU, which regulates fuel intake by means
of fuel pressure values inside the Common Rail, choking the
input entrance of fuel in the injection pump. The digital signal
varies the opening of the valve in proportion to the quantity of
fuel required for the Common Rail.
Important
• Refer to Par. 2.9.3.
2.15.4 EGR valve (D)
A device that provides for exhaust gas recovery that is controlled
by ECU, which, according to acceleration parameters, RPM and
power requested, varies the opening and closing of the valve.
The device has an integrated ECU, which, on each start-up of
the control panel, executes an operation self-check.
In the event of a malfunction, it sends a signal to ECU, which,
in turn, signals the anomaly on the control panel.
Characteristics:
• Type Dell'Orto EGV A16
• Operating/storage temperature: -30°C / +130°C.
