10.2.1.10 Engine lubrication system
The Rotax 912 iS Sport engine has dry sump forced lubrication. General overview is shown
on Fig. 10-7.
The oil pump is driven by the camshaft.The main oil pump sucks the engine oil from oil tank
(1)
– see Fig. 10-8, via the oil cooler (3) and forces it through the oil filter to the individual
points of lubrication (also lubricates the propeller governor). The surplus oil emerging from
the points of lubrication accumulates the bottom of the crankcase and is forced back to the
oil tank by the crankcase blow-by gases. The oil circuit is vented via nipple in the oil tank.
