For the completion of the lubrication system only the following connections need to be
established:
Lubrication circuit engine (main oil pump)
oil tank (outlet) ➪ oil cooler
oil cooler ➪ oil pump (inlet)
oil return ➪ oil tank (inlet)
oil tank ➪ venting line
Oil circuit turbo charger (suction pump)
oil return ➪ oil tank (inlet)
◆ NOTE: In the serial version of the engine an oil tank is included, but no
provision is made for attachment of an oil cooler.
▲ WARNING: Certification of oil cooler and connections to the latest requirements
such as FAR and JAR has to be conducted by the aircraft builder.
13.2) Limits of operation
▲ WARNING: The lubrication system has to be designed such that operating
temperatures will not exceed the specified limits.
Oil pressure: For oil pressure sensor see ill. 75/76.
max. ........................................................................ 7 bar (100 p.s.i.)
■ ATTENTION: Permitted at engine start for a short period.
min. ......................................................................... 1,5 bar (22 p.s.i.)
normal..................................................................... 1,5 ÷ 5 bar (22 - 73 p.s.i.)
■ ATTENTION: At full throttle operation the depression at pump inlet must be 0,3 bar
(4,4 p.s.i.) below the ambient pressure. Reading must be taken at a
distance of max. 100 mm (4") before pump inlet. See ill. 24.
Oil temperature: Oil temperature sensor, see ill. 73/74.
max. ........................................................................ 130°
C (266 ° F)
min. ......................................................................... 50
O
C (120 ° F)
most favourable oil temperature ............................. ca. 90 ÷ 110
O
C (190 - 250 ° F)
▲ WARNING: At operation below nominal oil temperature formation of condensate
in the lubrication system might influence oil quality.
