Detailed description: Injectors
The injectors are connected directly to the fuel rail and are mounted in heat insulated bushings in the cylinder head ahead of the intake valves.
An injector comprises a valve body and nozzle with magneto armature. The valve body contains a magnetic coil and a guide for the nozzle. The injectors are controlled electromagnetically and are opened and closed by electrical impulses from the engine control module.
The injectors are of the two-hole type. This means that they inject one jet of fuel into each intake valve.
The nozzles are secured by clips to the fuel rail. It is essential with regard to emissions and engine performance that the nozzles are positioned and secured correctly.
