Cooling Systems
14.1 Air
Ducts
•
The engine should be installed using RAM AIR ducts provided with the engine.
•
Each duct must have a 25mm hole at the inside top front to bleed air over the crankcase.
•
Cylinder and cylinder head cooling is achieved by ducting air over the cylinders and
heads. The Static Air Pressure inside the cooling ducts must not be lower than 4.3cm
(1.7”) water gauge at 1.3 times the stall speed.
•
The cooling ducts provided are only a starting point in establishing effective engine
cooling. The ducts may require to be increased in size and additional baffles provided to
achieve the specified maximum cylinder head temperature of 180
o
C (see page 19).
14.2 Oil
Cooling
•
The dipstick cap must be screwed fully in before removal for reading oil level.
•
An oil cooler adapter is supplied with the engine and is fitted under the oil filter.
•
Oil coolers are available from Jabiru Aircraft.
•
Unless operating in environments of low temperatures, oil coolers are mandatory.
•
The cooler can be plumbed either way to the adaptor – flow direction through the cooler is
not important.
•
In continuous operation oil temperatures between 80
°
C and 90
°
C (176
°
F – 194
°
F) are
desirable. 70
°
C (158
°
F) is the minimum allowable temperature for continuous running and
100
°
C (212
°
F) is the maximum allowable temperature for continuous running.
•
Over filling with oil is not desirable. Over filling may result in elevated temperatures and
excessive oil loss through the crankcase vent.
•
When installed in a tail-dragger aircraft, recalibration of the dipstick will be required by the
owner.
•
Hoses should be nominally 10mm (3/8”) bore.
•
Hoses must be changed every two years or when visible degradation (cracking,
hardening) is visible during inspections.
The limits in the Specification Sheet, contained in Appendix B, must be strictly adhered
to. Warranty will not be paid on engine damage attributed to overheating of cylinders
or oil.
