Engine Performance - Functional Description: Injector: Notes
The injector sprays the fuel into the combustion chamber under high pressure. The injector opens the tip of the nozzle needle outwards and forms a ring gap that is only a few micrometers wide. The ring gap shapes the high precision injection and ensures even, cone-shaped divergence. The piezo-electric activation has the following advantages compared to activation via solenoid coils:
- improved possibilities for multiple fuel injection due to rapid switching times with very short response times This results in significant improvements with regard to pollutant emission as well as fuel consumption.
