FOR SIMULATION USE ONLY
Auto Mixture System
The Jabiru J2200 engine has an auto mixture system and a manual choke.
To simulate this system within the boundaries of Microsoft Flight Simulator a
system is incorporated which operates as follows;
1. If the choke lever is pulled out, the fuel/air mixture to the engine is set to full
rich.
2. If the choke lever is pushed in, the fuel/air mixture to the engine is
controlled by internal logic which sets the fuel/air mixture automatically every
second to the best possible mixture for the current flight conditions.
Carburettor Heat
The carburettor heat control is a push-pull control located in the centre of the
lower section of the instrument panel. With the control pushed fully forward
(in), cold filtered air is selected. Fully aft (heat ON) selects heated filtered air
from a muff around the exhaust pipes. The knob is a rectangular shape.
Engine Instruments
Engine operation is monitored by a tachometer, oil pressure and oil
temperature, fuel pressure and cylinder head temperature gauges. These
instruments are located in the instrument panel in front of the pilot and are
marked with green arcs to indicate the normal operating range, yellow arcs
to indicate precautionary ranges and red lines at the maximum/minimum
allowable limits.
These limits and gauge markings are also given in Section 2 of this manual.
Engine Oil System
Oil for engine lubrication is supplied from a sump at the bottom of the engine.
The oil capacity of the engine is 2.3 litres (2.02 US quarts). Oil is drawn from the
sump through an oil suction strainer screen into the engine driven oil pump.
An adaptor on the engine underneath the oil filter directs oil through the oil
cooler. On returning to the engine, the oil passes through the full flow
replaceable element oil filter. The filtered oil then enters a pressure relief valve
that regulates the engine oil pressure by allowing excessive oil to return to the
sump, while the remaining oil under pressure is circulated to the various
engine components for lubrication. Residual oil returns to the sump by gravity
flow.
