Well, maybe he meant that they don't have a butterfly in the
venturi  
-- no throttle plate, so to speak.


That's precisely what he was
getting at.  Technically a "Throttle" is a valve which restricts fluid flow. 
On a gas engine, the throttle is the butterfly valve that restricts the air
flowing into the engine, which then creates a vacuum behind it.  Diesels do
not have this, and it is not correct to call the injectors or anything
controlling the injectors a "Throttle".  
A pedal controlling a throttle can
also be called a throttle, but again, it wouldn't be correct to call the pedal
in a diesel automobile a "Throttle".  "Accelerator" would be a better term.
