Re: [Land-speed] Tires,Mileage,etc/non LSR ?

Well, I see it as a fundamental difference between the two engine cycles.  In
a diesel engine, you have the same mass of air at a given RPM regardless of
the position of your pedal.  No power is wasted by creating a vacuum in the
intake manifold (AKA Throttling losses).  Several companies are currently
investigating methods of eliminating the need for a throttle in a gasoline
engine.  The common way I've read about is a sort of Diesel/Otto cycle hybrid
called HCCI.  GM and Mercedes both have functional prototypes.

    I don't know, I think we are splitting hairs
here. The pedal controls 
the flow be it air, electricity, fuel or steam and I
believe the term 
throttle is applicable.
