LPG in its liquid phase leaves the tank by means
of the multivalve (which through the external filler socket is
also used to refuel with LPG) and is fed to the engine compartment
through a pipe and LPG solenoid valve. The valve will only allow
the gas to pass through when the engine is running and switched on
in the gas position.
In the next phase a regulator reduces the pressure, transforming
liquid LPG into gas. From the regulator LPG goes to the air/fuel
mixer. It controls the flow of gas according to the requirement of
the engine (represented by the vacuum generated in the mixing
devices) thus ensuring optimum carburation in terms of driving,
consumption and emissions. |

The switch/gauge mod. 096, in addition to
other functions, facilitates petrol starting. Thereafter a
solenoid valve automatically switches over to gas supply. The
valve also allows the user to switch between petrol and LPG at any
time, and displays LPG levels in the storage tank. During gas
operation, the electronic emulator cuts off the flow of petrol to
the engine, whereas during petrol operation the flow of LPG to the
engine is cut off by the solenoid valve. |
