Abstract: A throttle body fuel distribution assembly includes a throttle body assembly having a throttle body housing and a throttle bore for inducting an airflow, a fuel injector coupled to the throttle body assembly, and a fuel dissemination device for dispersing fuel sprayed by the fuel injector into the airflow through the throttle bore. In one variation, a throttle body fuel distribution assembly includes a throttle valve assembly for controlling the airflow through the throttle bore. In some variations, the fuel spray is diverted in a direction resistive to the direction of the airflow through the throttle bore. In yet another aspect, a throttle body injection system for an internal combustion engine includes a throttle body assembly having an air conduit, an injector assembly coupled to the throttle body assembly, and a fuel deflector for deflecting fuel into the airflow.
