Injector For Engines With Direct Petrol Injection

As all the parts of the injector are multiple laser-welded, it is not possible tocutaway these parts any further. The benefitof these injectors is that they switch extremely quickly and thus injectminimum quantities of fuel, which makes multiple injection (3) possible. 

The followingcan be seen:
Electrical connections for voltage supply to the piezo-actor module
Cutaway injector housing and interior housing
Teflon ringfor sealing in the cylinder head
Fuel flow (high pressure)
O-ring toseal the leakage line
Nozzle module
Coupler module.
