BRP-Powertrain

INSTALLATION MANUAL

16) Air intake system

See Fig. 64.

The intake system is determined essentially by the demands of engine and of the
acceptable noise emission on the intake side. An airbox can be supplied by BRP-
Powertrain as an option.

Performance data as specified and limits of operation can only be warranted by
employment of the genuine ROTAX airbox.

■

  CAUTION:

The performance is given at ISA (15 °C) (59 F°) condition only. Engine
is equipped with unchanged ROTAX tuned exhaust muffler system
and air intake box.

If it will be necessary to use a different airbox or a modified genuine ROTAX airbox for
reasons of installation the certification to the latest requirements such as FAR and
EASA has to be conducted by the aircraft manufacturer.

◆

  NOTE:

If an airbox or genuine ROTAX airbox is retrofitted at a ROTAX 912 (A,
F, UL) Series, a change in the carb jetting is required. See Illustrated
Parts Catalog 912/914 chapter 22 and/or SB-912-044 "Use of the
ROTAX supplied airbox", latest issue.

16.1) Operating limits

Fuel-mixture distribution:

Low (cold) air temperature in the airbox is favourable for engine performance
and to reduce knocking tendency at combustion.

The certification to the latest requirements such as FAR and EASA has to be
conducted by the aircraft manufacturer.

■

 CAUTION:

Any changes on the air intake system (e.g. modification on the
airbox etc.) can affect the flow rate in the air intake system and
the fuel mixture ratio. In the course of certification the fuel
mixture process must be proofed by a CO-measurement.

CO-Measurement:

CO-Emission ......................... min. 3,0 % CO (wide open throttle (WOT);

an rpm of min. 5200 1/min needs to be achieved)

Measurement in original configuration of aircraft e.g. with installed cowling.

Measured on each single cylinder. Measuring point is the same as the EGT-
measurement. See section "Exhaust system".
