2.9.4 Injector
It is a device used to introduce fuel, in the form of one or more jets
that are adequately pulverised and suitably oriented directly into the
combustion chamber. They consist of a metallic body that internally
provides a mobile element that acts on the needle: this, rising against
the action of a calibrated spring, allows the release of fuel under high
pressure.
Opening pressure: 260-268 bar (3770-3886 PSI)
Important
•
The injectors are calibrated individually.
•
Fuel contamination causes serious damage to the injection
system.
