Injector

A nozzle assembly of an injector and an injector are disclosed. The nozzle has a body which cooperates with a valve member to control an outlet path. The outlet comprises a guidance channel 72 which leads to a spray hole 60, 62. The grooves 72 and outlet orifice 60,62 are arranged to force the flow...

More Information
Summary:A nozzle assembly of an injector and an injector are disclosed. The nozzle has a body which cooperates with a valve member to control an outlet path. The outlet comprises a guidance channel 72 which leads to a spray hole 60, 62. The grooves 72 and outlet orifice 60,62 are arranged to force the flow to swirl S when entering the spray hole 60,62. There may be several branches 74 of the channel leading to the spray hole. The nozzle may include a plurality of spray holes which may be joined by the guidance channel. The application extends to a Selective Catalytic Reduction (SCR) injector adapted to spray into the exhaust pipe on an internal combustion engine. The induction of swirl enhances the atomization performance of the nozzle, allowing for the number of holes needed to be minimised. This reduces machining costs and increases plugging resistance.
