LPG INJECTORS
There are four injectors fig. 6, specially
designed for LPG, mounted on the intake
manifold near the cylinder head, one for
each inlet duct; they are supplied with LPG
in a gaseous state at a constant pressure
and are controlled by a specific electron-
ic control unit.
A gas pressure and temperature sensor
that sends an appropriate electrical signal
in order to determine the LPG injection
time is fitted on the injectors.
