I am not sure I understand Ed. A throttle body is merely a butterfly
valve. The injectors could be mounted anywhere along the intake tube.
Tracy, Everett and Mazda mount them close to the rotor
housing. All late aircraft engines with fuel injection inject
the fuel close to the intake port. 

The advantages are the pipes carry only air and not fuel
vapor. It is a lot harder to get an intake manifold to 
distribute fuel vapor evenly. That is one of the main advantages
of fuel injection in the first place. Years were spent on intake
manifold development before fuel injection.

Over the years different positions have been tried but
most engine manufacturers have settled on placing the injectors
as close to the intake port as possible.
