(OVERVIEW)

SMR2003-022_06_02A.FM

The Rotax Fuel Injection (RFI) is a semi-direct elec-
tronic fuel injection system.

Fuel is injected into each cylinder through the rear
transfer port. With this design, the injector is not
exposed to high combustion pressure, tempera-
ture and contaminants.

This system delivers the following benefits:

– easier cold engine starting (no choke)

– easier hot engine starting

– improved idling

– better throttle response

– better fuel economy

– no fuel valve.

This system has the advantage of optimizing the
engine power, fuel economy and emission con-
trols under all engine operating conditions by man-
aging both the fuel injection duration and ignition
timing.

The Rotax Fuel Injection (RFI) is composed of the
3 following basic systems:

1. air induction 

2. fuel delivery 

3. electronic management.

AIR INDUCTION

A single throttle body (56 mm) breath through the
air intake silencer to provide a sufficient amount
of air for the engine operation.

THROTTLE BODY

FUEL DELIVERY

FUEL PUMP

An electric fuel pump provides fuel pressure and
flow rate to the system.

FUEL PUMP

FUEL PRESSURE REGULATOR

A regulator maintains a constant fuel pressure of
386 - 414 kPa (56 - 60 PSI).
