OIL SYSTEM – DESCRIPTION AND OPERATION
Oil temperature below 90°C
The oil contained in the tank (item 1 in Figure 2) is sucked from the oil pump
(item 7) which pressurizes the circuit.
The oil pressure is monitored in the cockpit by means of a dedicated instrument.
The oil is then routed through the thermostatic valve (item 2) which is fitted with
two thermal sensors (item 3 and 4) allowing for a partial radiator passage occlu-
sion for temperature below 90°C.
Once came to the pump, oil is transferred to the engine lubrication circuit and
then to the cartridge filtering element integrated in the engine. The oil is then
conveyed in the oil reservoir (Rotax part).

Oil temperature 90°C to 100°C
As above described, the oil circulates for effect of the pump (item 7 in Figure 3),
but in this case the first thermal sensor (item 3) set to 90°C allows for oil passing
through the radiator where oil is cooled.
It is then mixed with the other oil and it reaches the engine carter where it is fil-
tered. The oil is then gathered in the oil reservoir.
