Abstract

A fuel injector comprises an injector body and an air assisting adapter. The adapter is attached to the injector body and has a fuel passage for guiding spray of injected fuel. The fuel passage is divided into two directions. A plurality of air introduction holes are communicated with the fuel passage, so that pressurized air is introduced into the fuel passage to atomize the injected fuel. The air introduction holes open to the passage at a position where the particle size of the injected fuel starts to reduce. This position is 4 mm to 5 mm away in the downstream direction from an injection port plate of the injector body.
