7.4) Lubrication system
The engines is provided with a dry sump forced lubrication sys-
tem with a main oil pump with integrated pressure regulator.
The airframe manufacturer is responsible for the main layout
and the component selection for the lubrication system.
Lubrication The main oil pump sucks the motor oil from the oil tank via oil
radiator and forces it through the oil filter to the points of lubrica-
tion (lubricates also the plain bearings of the turbocharger and
the propeller governor).
NOTE
The oil radiator is optional.
Crankcase
The surplus of oil emerging from the points of lubrication accu-
mulates on the bottom of crankcase and is forced back to the oil
tank by the piston blow-by gases.
Oil pump The oil pumps are driven by the camshaft.
Oil circuit vented
The oil circuit is vented via bore on the oil tank.
Oil temperature
sensor
The oil temperature sensor for reading of the oil inlet tempera-
ture is located on the oil pump housing.
Turbocharger The turbocharger is lubricated via a separate oil line (from the
main oil pump).
The oil emerging from the turbocharger collects in a stainless
steel oil sump and is sucked back to the secondary oil pump
and then pumps back to the main oil tank via the oil line.
