Fuel injecting valve for fuel injection systems of internal combustion engine, has atomizing device, which is acted as multi-fan-jet nozzle with multiple pair of holes consists of two injection openings

摘要

The fuel injecting valve has a valve longitudinal axis (2), a valve seat body (16) that comprises a fixed valve seat (29), and a valve closure body (7) act together with the valve seat. The valve closure body is moved along the valve longitudinal axis, and has an exhaust port arranged in the valve seat body and has a down stream of the valve seat arranged in atomizing device. An atomizing device is acted as multi-fan-jet nozzle (23) with multiple pair of holes and consists of two injection openings, whose injection port axes runs convergent to each other for attaining a jet collision.
