7.7.5 Engine controls
Fig. 9 Engine RPM controls
Rotax-912iS engine is equipped with an electronic control unit (ECU) for fuel injection into
intake manifolds immediately before the intake valves. The ECU generates signals for fuel
injection and mixture ignition according to the programmed algorithms and data from a
number of sensors, including the throttle valve position sensor. Engine speed is controlled
by moving the throttle valve from closed to fully open position using the throttle lever 1 (
Fig.
9 ) connected with the control column (2) based on the bracket (3). The cable is passed
through the flexible sheath (5) and clip (6). The throttle lever friction force can be adjusted
on the ground by tightening the bolt (7).
Rearmost throttle lever position corresponds to MIN engine RPM, the foremost position
– to
MAX engine RPM. Pulling the friction force adjusting lever back increases the throttle lever
friction, pushing it forward
– reduces.
7.7.6 Brake control system
The main wheel brakes ( Fig. 10 ) are actuated hydraulically using the brake lever (2)
(installed next to the throttle lever 3) controlling the pressure supplied from the master
cylinder (1) to the slave cylinders (5) in the wheels.
The main LG wheels have disk brakes. The cylinders are connected to each other with
copper tubing 6 with outside diameter of 3 mm. The master cylinder (1) is connected with a
hose (8) to the extension tank (7), installed on the firewall in the engine compartment.
When the brake lever is pulled the brake pads squeeze the brake disc creating the braking
moment proportional to the applied force.
A-32 is equipped also with a parking brake, which is actuated with a lever (4) on the central
console. To use the parking brake, set the lever to 'Parking brake ON', then pull and release
the brake lever. The brake pads will remain pressed to the brake disc. To release the parking
brake set its control lever to its initial position ('Parking brake OFF').
