ABSTRACT:
The atomizer fits over the outlet of the fuel injector and comprises a thimble-shaped inner part that nests within a thimble-shaped outer part. Both inner and outer parts comprise holes in their end walls through which injected liquid fuel from the injector outlet passes. The inner and outer parts cooperatively define passages through which assist air is conveyed to the aforementioned holes to aid in the atomization of the injected fuel. Several embodiments of atomizers are disclosed.
