Abstract
A diesel fuel injector based on a hollow spray structure induced by vortex cavitation in a nozzle, including a needle valve, a nozzle body, a plurality of spray holes, and a sac chamber. An axis of the needle valve coincides with an axis of the nozzle body. The spray holes are evenly distributed on a head of the nozzle body, and each have a converging conical structure. An inlet end of the spray hole is communicated with the sac chamber. The sac chamber consists of a hemispherical cavity and a cylindrical cavity.
