Principle of operation English
The “ GALILEO ” is a micro-processor controlled system for the management of carburetion on GAS powered
vehicles. It is programmable, it’s an adaptive learn system managed by micro-controller, and able to maintain
stoichiometric ratio between AIR and GAS (C.N.G. or L.P.G.) under any operational condition by utilizing the
following inputs:
• OXYGEN SENSOR
• RPM
• THROTTLE POSITION SENSOR (T.P.S.)
The signal of the above sensors is different according to the vehicle model. Moreover, the operational characteristics
are also different according to the vehicle. To correctly manage these signals, the “ GALILEO ” requires programming
that can be achieved by means of one of the following devices.
• PERSONAL COMPUTER on which a specific SOFTWARE (Code AEB003) program is installed, communicating
with the “ GALILEO ” through SERIAL INTERFACE (Code AEB001)
• HAND-HELD TESTER (Code AEB215, updated to 2.10 version)
The “ GALILEO ” also makes it possible to simulate the correct operation of the Oxygen Sensor during GAS
operation without the aid of external emulators.
The GAS modulation is achieved by means of an electro-mechanical actuator installed in the vapour hose connecting
the pressure regulator to the mixer.
The electro-mechanical actuator consists of a plastic body provided with a calibrated orifice through which the GAS
transits. A stepper motor is mounted on the plastic body. The stepper motor modulates the amount of GAS
according to the engine needs.
Since the “ GALILEO ” is an adaptive learn system, it does not require periodic adjustments. The only manual
adjustment to be performed is the idle mixture on the pressure regulator. It is important that this adjustment is
performed with great precision.
Although the “ GALILEO ” is capable of modulating carburetion at idle, this modulation is not optimized if the manual
adjustment is poorly performed, as the modulating ability of the “ GALILEO ” is limited at idle, and only indicated for
fine adjustments.
The “
GALILEO
” E.C.U. manages the operation of the GAS electrovalves directly. The switch provided is used
only to select the fuel used.
