Fuel injection-ignition system components
The injector is made up of a body (2) and a needle (3) which is connected to the armature (4). The
needle is pressed against the seat by a helical spring (5), whose loading is determined by an
adjustable pushrod (6). The winding (7) is accommodated inside the injector body at the rear end,
whereas the injector nose (8) at the front end incorporates needle seat and guide.
See Section L 6 for injector removal and installation instructions.
Note

The outfeed of the fuel must be steady and the jet must be atomised, without drops.

special additive

to the tank at regular intervals. This cleans the critical fuel passages.
Lambda sensor
The lambda sensor (1), located on the exhaust pipe, is the sensor giving the control unit information
about the quantity of oxygen in the exhaust gases. This helps the electronic control unit in maintaining
optimum air-fuel ratio.
