LPG INJECTORS
There are four injectors fig. 6, specially
designed for LPG, mounted on a special
bracket on the cylinder head and connec-
ted, by means of dedicated pipes, to the
individual intake ducts; they are supplied
with LPG in a gaseous state at a constant
pressure and are operated by a dedicated
electronic control unit.
A gas pressure and temperature sensor
mounted on the injectors sends an elec-
trical signal to determine the LPG injec-
tion time.
