13) Lubrication system
13.1) Description of the system
See Ill. 22.
The BOMBARDIER-ROTAX 914 F engine is provided with a dry sump forced
lubrication system with a main oil pump with integrated pressure regulator and a n
additional suction pump.
◆ NOTE: The oil pumps are driven by the camshaft.
The main oil pump sucks the motor oil from the oil tank Q via the oil cooler W and
forces it through the oil filter to the points of lubrication (lubricates also the plain
bearings of the turbo charger and the propeller governor).
The surplus oil emerging from the points of lubrication accumulates on the bottom of
crankcase and is forced back to the oil tank by the blow-by gases.
The turbo charger is lubricated via a separate oil line E from the main oil pump.
The oil emerging from the lower placed turbo charger collects in the oil sump and is
pumped back by a separate pump to the oil tank via the oil line R.
◆ NOTE: The oil circuit is vented via bore T in the oil tank.
