2 Fill the water container (2)
with clean water and close the
cover of the water container.
3 Check and turn the valve (1)
to the choosen compressor.
4 Open the slid valve (3).
5 Close the valve (3) after 5 - 10 seconds.
6 Repeat the readings taken in step 1 above for comparative
purposes. The success of injection can be recognized by the change
in charge air pressure and in the exhaust gas temperature.
7 Run the engine for 5 minutes more
after the compressor has
been cleaned with water. Doing so it is ensured that all the parts in
the compressor side are completely dry.
8 Repeat step 1 above
for the other compressor
Note! If injection is not successful, it must not be repeated before ten
minutes.
15.4 Maintenance of charge air cooler
15.4.1 General maintenance
1 Condensate from the air is drained through a small hole/
pipe (6), Fig 15-1, at the bottom of the cooler housing, after the
insert, and at the opposite end plate of the air manifold. Examine
regularly that the pipe is open by checking the air flow when
running.
If water keeps on dripping or flowing from the draining pipe for a
longer period (unless running all the time in conditions with very high
humidity), the cooler insert may be leaky and must be dismantled
and pressure tested.
2 At longer stops, the cooler should be either completely filled or
completely empty, as a half-filled cooler increases the risk of corro-
sion. If there is a risk of that the water level in the system goes down
when the engine is stopped, drain the cooler completely. Open the
air vent screw (3), Fig 15-1, to avoid vacuum when draining.
3 Clean and pressure test the cooler
at intervals according to
chapter 04. or if the receiver temperature cannot be held within
stipulated values at full load.
4 Always when cleaning, check for corrosion.
