ENGINE SYSTEMS

The engine systems and engine-related systems
of the Canadair Challenger CL-601-3A are:

• Engine oil system

• Engine fuel system
• Ignition system
• Engine control
• Instrumentation
• Engine starting
• Engine speed control and APR systems
• Engine vibration-monitoring system
ENGINE OIL SYSTEM
General
The engine oil system is completely self-con-
tained and fully automated. The engine oil
system provides for cooling and lubrication of
the engine bearings and the accessory gearbox
in addition to adding heat to the unmetered fuel
system through the oil/fuel heat exchanger. An
oil replenishment system is installed in the
rear equipment bay.
Major Components
Oil Tank
An oil tank is mounted at the 11 o'clock po-
sition on each engine. The tank contains a
gravity filler with a dipstick mounted on the
filler cap. A master chip detector forms part
of the oil tank drain plug.
Oil-Replenishing System
The oil tank can be serviced through the in-
tegral gravity filler or through the replenish-
ment system in the rear equipment bay.

Control
An oil-replenishing control panel, powered
from the battery direct bus (Figure 7-3) con-
tains a power switch, a green power ON light,
and two green oil full switchlights labeled "LH
FULL" and "RH FULL." These two lights have
a press-to-test feature. A three-position man-
ual selector valve labeled "L," "OFF," and "R"
is located adjacent to the control panel. In ad-
dition to selecting the tank for servicing, the
valve controls the power supply to the replen-
ishment pump that supplies oil from the tank
to the selected engine's oil tank.

Indication
The appropriate oil full switchlight (Figure 7-
3) illuminates when the associated engine oil
tank is full.
Oil Pump
An oil pump containing one pressure element
and six scavenge elements is driven by the ac-
cessory gearbox.
The pressure element provides lubrication of the
main engine bearings and the accessory gearbox.
The scavenge elements provide for direct scav-
enging of the compressor and turbine bearings
and the accessory gearbox.
