Auxiliary Blowers
The engine is provided with a minimum of two
electrically driven auxiliary blowers, the actual
number depending on the number of cylinders as
well as the turbocharger make and amount.
The auxiliary blowers are integrated in the reversing
chamber below the scavenge air cooler. Between
the scavenge air cooler and the scavenge air re-
ceiver, nonreturn valves are fitted which close
automatically when the auxiliary blowers start
supplying the scavenge air.
Auxiliary blower operation
The auxiliary blowers start operating consecu-
tively before the engine is started and will ensure
complete scavenging of the cylinders in the start-
ing phase, thus providing the best conditions for a
safe start.
During operation of the engine, the auxiliary blow-
ers will start automatically whenever the blower
inlet pressure drops below a preset pressure,
corresponding to an engine load of approximately
25-35%.
The blowers will continue to operate until the
blower inlet pressure again exceeds the preset
pressure plus an appropriate hysteresis (i.e. taking
recent pressure history into account), correspond-
ing to an engine load of approximately 30-40%.
Emergency running
If one of the auxiliary blowers is out of function,
the other auxiliary blower will function in the sys-
tem, without any manual adjustment of the valves
being necessary.
