Appendix D – Normal Engine Figures
The following information is intended to allow an assessment of the engine’s performance
when installed in a known airframe with a known propeller.
20.1 Known Airframe / Engine Details
•
Jabiru SP (2 Seater)
•
Propeller 60” x 42” (1525mm x 1067mm) or
•
60” x 44” (1525mm x 1118mm)
20.2 Reference
Information:
•
Figures given are approximate guide only.
•
Engines installed in other aircraft with different prop loads, elevation and fuel types will
differ from the Jabiru airframe.
•
Poor installations will result in poor performance.
•
All air inlet junctions from outside the cowl to the carburettor inlet must be free of edges,
ledges and tight bends.
•
Carburettor inlet must have protection to the scat hose attachment (short glass tube or
Jabiru produced adaptor).
•
Air vent for the carburettor bowl must be routed to the filtered side of the air box.
•
Engines must be fitted with an oil cooler.
•
Engines work best at RPM quoted. Extended operation of the engine at other speeds may
result in reduced performance or engine damage. Engines fitted with coarser or finer
pitched props will cause variation from figures quoted and could cause excessive fuel
consumption and higher than normal CHT’s
•
Engines are jetted to a standard and must not be changed without discussion with Jabiru
Aircraft or local representative.
•
All figures given at sea level and at summer temp of around 25
