N3.1 INJECTOR SECTION
The new N 3.I pump injectors are capable, thanks to the higher injection pressure, of atomizing the fuel in the combustion chamber
to a greater extent, thus improving combustion and therefore reducing the polluting exhaust emissions.
The function of the fuel pressure damper located on the
delivery pipe between the fuel filter and the cylinder head is
to attenuate the supply return back pressure due to the
increase of the injection pressure.

This N.T.C. type sensor located on the water outlet sump on the engine head left measures coolant temperature for the various
operating logics with a hot or cold engine and identifies injection enrichment requirements for a cold engine or fuel reduction
requirements for a hot engine.
It is connected to electronic center pins 15/26.
