The high-pressure fuel injector HDEV 6 is a component of a gasoline-direct fuel-injection system of an otto cycle engine. The HDEV 6 is arranged between the fuel rail and the combustion chamber in the cylinder head.
The function of the HDEV 6 is to meter the high-pressurized fuel and achieve a targeted atomized air and fuel mixture in a defined location in the combustion chamber.
It is an inward opening solenoid injector which is optimized regarding high mass flow, fast opening and closing, leading to a very stable linearity.
The benefit of this injector is a high spray variability concerning hole numbers, spray shape, and spray angles. Also, the flow rate can be defined in a wide range.
Bosch offers the spray targeting design according to the individual customer requirements and can support with additional services, e.g. CFD Simulation, State of the art Spray measurements, and further services.
If your application conditions will not match the listed performance data, please ask for consultancy at Bosch Motorsport. Bosch offers cost effective production HDEV 6 on request.
