So that would mean it's horribly inefficient when used except in a very small range of operation, correct?

I really need to get the book ( you'd get a kick out of some of the drawings ) before I can best represent them (there are 12 0f them ).
Throttles are horrible! They have a Cd 1.11,not a pretty picture for passing fluids,gases,etc..
The Diesel has a low speed advantage over S.I.engines due to it's lack of throttle,which is lost around 80-mph,when S.I.-engined cars are operating closer to WOT,with higher volumetric efficiency of the open hole.
My CRX has a 3-BBL carb and at reasonable highway speed is at WOT for that 2nd "cruise" barrel which probably gives it some advantage over a partially-cracked large throttle-body of a EFI engine operating at high drag angle of attack.
