Figure 6. Wiring Diagram
10 Electrical Equipment
10.1 Alternator
The alternator fitted to the Jabiru 2200 engine is a single phase, permanently excited with a
regulator. The rotor is mounted on the flywheel with the stator mounted on the alternator
mount plate at the back of the engine. The alternator mount plate is also the mount for the
ignition coils and the vacuum pump.
Specifications
Power (Max): 120W Continuous
Note: The electrical system is Negative Earth.
10.2 Regulator
The regulator has been selected to match the voltage and current of the integral alternator.
Only Jabiru Part No. PI10652N should be used. (The regulator output voltage is 14 volts +
0.8 volt.).
Recommended wiring of regulator is positive and negative of the regulator directly to the
battery. A 20A fuse or circuit breaker may be used between the regulator & battery
10.3 Ignition
The ignition unit has dual breakerless transistorised ignition with the magnets mounted on the
flywheel and the coils mounted on the alternator mount plate.
The current from the coils flows to the distributor from where it is distributed to the spark
plugs. (See also Regulator Wiring at Page 12.)
• The ignition is turned off by grounding the coils via the ignition switches.
• The ignition is timed to 25o BTDC
• The temperature limit for the ignition coils is 70oC. This should be checked by the
installer. It is recommended that pipes of 12mm dia be fitted to the top rear of each air
duct directing air onto the coils for cooling purposes.
• Coil gaps are set at 0.25mm to 0.30mm (0.010” to 0.012”).

10.4 Starter Motor
The starter is mounted on the top of the engine and drives the ring gear on the flywheel. The
motor is activated by engaging the starter button (the master switch has to be ON) which trips
the solenoid, hence current flows from the battery to the motor. The cable from Battery to
starter should be minimum 16mm2 copper.

11 Fuel Supply System
11.1 Fuel Tank
The fuel tank must be fitted with an outlet strainer of between 8 and 16 mesh per inch, with a
minimum total mesh area of 5 cm2.
11.2 Fuel Filtration
A Fuel filter capable of preventing the passage of particles larger than 0.1mm (100um) must
be installed between the fuel tank outlet and the fuel pump.
The filter must be present in the system for the fuel flow test. The size of the filter should
give consideration to allow adequate flow with a used filter.
A Ryco Z15 or similar filter has been used successfully.
11.3 Mechanical Fuel Pump
The mechanical fuel pump is mounted on the engine crankcase and is camshaft driven. It is
designed to supply fuel at the pressure described in the following paragraph. If fitted, the
electrical boost pump must also fulfill the fuel input criteria for the carburettor, given below.
11.4 Carburettor
A Bing constant depression type 94/40 is used. This carburettor has a minimum delivery
pressure of 5 kPa (0.75 Psi) and a maximum pressure of 20 kPa (3 psi). To confirm that the
fuel system is capable of delivering this pressure a fuel flow test must be performed.
To check pressure, insert a ‘T’ piece between the mechanical pump and the carby.
Test boost pump with engine off, then mechanical fuel pump with engine on, then
combine with electrical boost pump as well, before first flight.
A method for performing a fuel flow test is available from Jabiru if required. A drip deflector
to deflect overflowing fuel from the exhaust system is supplied as standard equipment on the
engine.
Because idle adjustments cannot accurately be made on the dynamometer (where every
engine is run before delivery), some adjustment of the 7mm idle set screw may be required.
A hot idle of around 900RPM is desirable. Fitting an earth strap from carby to crankcase is
recommended to eliminate possible radio interference.
11.4.1 Carburettor Tuning
Late in 2004 Jabiru Aircraft introduced a new system of needles and jets to the 2200 engine.
The new configuration lowers fuel consumption and is now standard. Details of the
configuration are given below:

Engine tuning may be significantly affected by extreme ranges of climate or propellers
which incur RPM values outside suggested figures (Appendix C).
Carburettor tuning must not be altered other than with advice from Jabiru Aircraft. If in
doubt, contact Jabiru Aircraft or our local representative
11.5 Fuel Lines
Fuel lines are nominally 6mm bore. All hoses forward of the firewall require fire resistant
sheathing and those between moving sections such as between engine and firewall should
be flexible. Hoses must be changed every two years, though if there are visible signs of
degradation (such as cracking or hardening) the hose should be changed immediately.

12.1 SCAT HOSE
Remove at each 50 hourly inspection one end of each scat hose. Inspect for holes, leaks
and condition of helical wound in a wire former. Replace if any signs of corrosion is evident.
12.2 Air Filter
• The induction system must not cause positive RAM induction pressure as this will have an
unpredictable affect the fuel/air mixture supplied to the engine.
• The filter must be capable of supplying 250 kg/hr (550 pph) of air
• The filter may have to be changed at regular intervals if the engine is to be used in a dusty

13 Exhaust System
• An exhaust system is provided with the engine. Both Pusher and Tractor systems are
available.
• Muffler Volume – Capacity 3 litres
• Back pressure at Takeoff Performance – Max 0.2 bar (2.9 psi). Readings taken 70mm
from muffler flange connections. Only complete mufflers supplied with Jabiru Aircraft are
welded – all others require tail pipes to be TIG welded to the muffler body. NOTE: Drilled
ends of pipes go inside muffler cavity. The tail pipes go completely through the muffler
body and are welded on both top and bottom.
• When fitting the muffler one or more of the exhaust pipes can be loosened at the
connection to the cylinder head to allow easy fit of the muffler. They then must be
tightened.
• Exhaust Gas Temperature (EGT) - Nominal 650
100mm from the exhaust manifold flange.

14 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 180oC (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.

19 Appendix C – Jabiru Engine Installation Tips
19.1 Prop
• For optimal performance, Jabiru engines require 2800 – 2900 RPM at take off and 3200
in the air straight and level. This may vary with aircraft and prop type, but variation
beyond these limits will affect tuning and in extreme cases may result in damage to the
engine.
• Carby tuning must not be altered other than with advice from Jabiru Aircraft. If in doubt,
contact Jabiru Aircraft or our local representative.
19.2 Tacho
• Ensure gauge is reading correctly. While large errors will be obvious, smaller errors are
harder to pick and it is recommended to check the gauge reading with another instrument
(such as a hand-held optical prop-tach)
19.3 Cooling
• Cowls should have adequate entry and exit areas. As a general guide, cowl outlets
should have approximately 3 times as much area as the inlets.
• Care must be taken not to flood the cowl area with oil cooler air (excessive oil cooler duct
size). Too much air coming in through the oil cooler will reduce the amount of air flowing
through the ram air ducts & increase CHTs.
• Air ducts as supplied are starting points and for best performance must be optimized by
the builder. Poor connections and air gaps around ducts/cooler etc give second rate
cooling
Damage caused by overheating due to poor installation techniques would not be
covered under warranty
19.4 Air Induction
• Air must enter from outside the cowl.
• All scat hoses should have only slight bends, with all sharp edges removed from the
induction path (including hot air sources).
• Ensure the filter used has adequate size.
19.5 Carburettor
• The bowl vent line must be connected to the filtered side of air box.
• Ensure that the two sense holes on the rear of venturi (intake side of carburettor) have not
been obscured.
• Set engine idle when warm.
• Ensure throttle and choke movement is correct.

Installation Manual Jabiru 2200 Aircraft Engine
19.6 Fuel Pump
• Ensure boost pump is not capable of more than 3 lb (20 kPa) pressure.
19.7 Oil
• Expel inhibiting oil from cylinders and pressure up (wind engine on starter until a the oil
pressure gauge shows a reading) before first start.
• Ensure correct run-in type oil is used for the first 25 – 30 hours to ensure proper ring
bedding-in.
• Once past the initial 25-30 hours, ensure the oil used meets the specifications given
above.
• Oil coolers are mandatory unless operating in very cold ambient temperatures. Refer to
Oil Cooling section above for allowable oil operating temperature ranges.
• Do not overfill the engine – this may result in high oil temperatures.
19.8 Fuel
• Avgas 100LL
• MOGAS above 95 Octane RON.
• Ensure a suitable fuel filter is used.
• Ensure the fuel tank is properly vented.
19.9 Oil Overflow
• Use a small collector bottle to catch engine oil venting.
19.10 Heads/Valves
• See section on early operation
• Check Head bolt tensions at regular intervals.
19.11 Additives
• No Oil or fuel additives should be used.
•
Use of oil or fuel additives will void warranty.
19.12 Temperature
• Refer to correct temperature operation of the engine
19.13 Connections
• “G” terminal on oil pressure sender is connected to gauge.
• “W” terminal on oil pressure sender can be connected to a warning light
• Regulator should be connected as per instructions above.
• Oil temp terminal connects to gauge per instructions included with gauge.

• CHT sensor ring under spark plug connects to gauge.
• EGT (optional) connects to gauge.
• Fuel hoses/oil hoses as required. Hoses must be protected by fire sleeve.
• Throttle/choke connected & movement adjusted.
• Carburettor heat arrangement working
• Correct scat hoses and directions
• Run hose from sump vent pipe to collection bottle.
19.14 Contact
• Check for contact of engine, cooler or ducts on cowl. Any contact will cause excessive
vibration & if the oil cooler is rubbing it will eventually fail & leak.
19.15 Warranty
Damage caused by overheating due to poor installation techniques would not be
covered under warranty.
Operation of the engine on non approved oils and fuel will likewise not be covered
19.16 Performance
• Overall performance of engine and airframe depends on correct installation and prop
match
19.17 Coils
• When installing new ignition coils the output leads go in the directon of prop rotation.
RHS coil output lead is up LHS coil output lead goes down – See page 24.
19.18 Induction
• It is strongly recommended that when connecting SCAT hose to the carburettor (intake
system) that some form of fiberglass tube or specially manufactured “Cobra Head” made
by Jabiru Aircraft be used. This will prevent air turbulence in front of the 2 sense holes on
the intake of the carby. Turbulence next to these sense holes can cause the engine to run
“out of tune” or “roughly” at certain revs

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 ˚C O.A.T

p) Fit throttle cable to carburetor. Note that Jabiru Aircraft kits come with a throttle cable
cut to length and with the correct end fitting attached. Engines used in firewall-forward
kits will be supplied with a length of throttle cable with no end – the builder must cut
the cable to length and fit the carburettor end fitting. 5/16” washers are used on the
cable end fitting (one washer either side of cable end fitting) to align cable. Use R-clip
to assemble.
q) Fit choke cable to carburettor. Use an R-clip to assemble. Note that the fuel line from
the fuel pump to the carburettor passes between the choke and throttle cables. Choke
cable not shown on Figure above.

s) Fit cylinder head temperature (CHT) sensor. The CHT sensor used in Jabiru aircraft is
a J-type thermocouple located under the rear spark plug of No: 4 cylinder. The VDO
310 980 Cylinder Head Temperature Gauge Kit is compatible with this sensor and is
installed as standard equipment in Jabiru Aircraft. Note that to ensure an accurate
temperature reading it is important to have the cold junction for the CHT (the plug
between the stiff thermocouple wires and the normal, plastic-insulated gauge wires)
located away from the heat of the engine. Refer to Figure at the beginning of the
engine installation section above.

exhaust pipe. Note that this fitting is not standard. The installation of the fitting is
best done at the time of order, though if required the exhaust pipe may be returned to
Jabiru and the fitting added. Note that in this case it will normally take around 2 weeks
before the pipe is returned to you. The fitting is welded to the pipe 100mm down from
the exhaust manifold mounting plate.
w) The Tachometer sensor used is a 6.35 x 22 mm analogue magnetic pick-up and is
fitted to a bracket on the alternator housing. Refer to photo below. The sensor picks up
on 2 tags fitted behind the flywheel.
