23C ELECTRICAL EQUIPMENT
General description
There are two types of electrical starting aid in use:
The fuelled starting aid and the port heater.
The fuelled starting aid (B1) is a device which is
operated electrically and ignites a controlled amount
of diesel fuel in the induction manifold to heat the
induction air. A heater coil in the body expands a
valve holder to allow fuel to flow into the device.
The fuel is ignited by the hot coil and the heated air
enters the induction manifold when the starter
motor is operated.
The port heater has an electrically heated coil that
heats the air as it enters the induction manifold.
Port heaters are used in a group of two or three.
Starting aid
To remove and to fit a fuelled23C-01A
starting aid
Consumable products:
POWERPART Threadlock (pipe) and
"Activator N 7649".
To remove
1 Disconnect the fuel pipe (A1) and the electrical
connection (A2).
2 Remove the starting aid.
To fit
1 Ensure that the contact faces of the manifold and
the starting aid are clean. Put the sealing washer
into position and fit the starting aid. Tighten the
starting aid to 31 Nm (23 lbf ft) 3,2 kgf m.
2 Check the fuel pipe and, if it is still full of fuel,
connect it to the starting aid. If the fuel has drained
from the pipe, eliminate the air from the pipe as
shown in paragraph 5 of operation 20A-08 or
20B-08.
3 Connect the electrical connection (A2).
Some engines which have water-to-air intercoolers
are fitted with twin fuelled starting aids (B3). These
starting aids are in a recess on top of the induction
manifold. In this situation, access to the electrical
terminals (B3) can be restricted if the starting aids
are not fitted correctly, see page 23C.03.
