Spray direction adjustment and plume shaping of impinging jet atomizer with asymmetric radial distribution

摘要

An injector nozzle for use with an internal combustion engine to guide and shape a fluid flow. The injector nozzle has a fluid flow guide provided at the outlet of the nozzle body. The fluid flow guide has a plurality of fluid passages that generate a plurality of airflow jets. Each passage has an orifice through which a respective air jet is discharged from the respective passage. The virtual extension and the plurality of passages converge to produce at least one focal point such that the plurality of airflow jets collide with each other to form a spray plume. The plurality of orifices of the plurality of fluid passages are arranged on a virtual circle on the outer surface of the fluid flow guide. The plurality of orifices are radially asymmetrically distributed on the virtual circle with respect to the central axis of the virtual circle. [Selection] Figure 1
