摘要

The injector (2) has a nozzle (4) comprising four orifices (120) each having a shape of an arc of circle. The orifices are arranged symmetrically around an axis (8) in a manner to define a circle. The orifices have reduced width and are connected to the interior of the injector by conduits. The conduits open at the interior of the injector by forming orifices having the shape same as that of the orifices (120). Independent claims are also included for the following: (a) an internal combustion engine for vehicle comprising a fuel injector (b) a vehicle comprising an internal combustion engine.
