Rotax 912 i Series Installation Manual page 98

Introduction
NOTE:
The fuel delivery is provided by two electric pumps connected in series
with bypass valves and engine will operate with either one or both pumps
running. The operating state of the pumps is manually selected. There are
2 injectors per cylinder (8 in. total). During engine run both injectors per
cylinder are in operation. If a failure is detected in any one injector the
injection period of the other one on that cylinder is adjusted for compensa-
tion.
The ECU operates all fuel injectors. A single blocked injector would be
compensated automatically. If a problem with a fuel injector occurs, the
fault is reported to the ECU and the pilot will be informed about a fault by
the instrument panel.

INSTALLATION MANUAL
The design of the fuel system is the responsibility of

WARNUNG
the aircraft manufacturer.
The fuel system must be designed to ensure that the
engine is supplied with sufficient fuel at the correct
pressure in every operational situation. Operating lim-
its must be adhered to!
Parallel hydraulic operation of the fuel pumps is not

permitted. The fuel pressure regulator can not cope
with the flow rate in this case and generator A can not
deploy the high consumption of current (Error entry in
the ECU).
It should be noted that the engine has an Eco and/or a Pow-
er-Mode. The Power-Mode is always active in Single-Lane
operation and is decisive for the range calculation. The fuel
consumption charts are available in the Operators Manual.
