The benefit of these injectors is that they switch extremely quickly and thus inject minimum quantities of fuel, which makes multiple injection (3) possible..
As all the parts of the injector are multiple laser-welded, it is not possible to cutaway these parts any further.
The following can be seen:
- Cutaway injector housing and interior housing
- Teflon ring for sealing in the cylinder head
- Nozzle module
- Coupler module
- Fuel flow (high pressure)
- O-ring to seal the leakage line
- Electrical connections for voltage supply to the piezo-actor module
