Wasted throttle power

[Reedtb2@cs.com]

Dear Prof. Parikh and All:

While looking for new sources of energy for the next millenium, please
consider "wasted throttle power".  

1)  Spark and diesel engines are both "hot air machines" (with <= 6% fuel
thrown in to heat the air).

2)  The diesel engine does not throttle the air - only the fuel, so there are
no "throttle losses" and the diesel burns from lean to very lean and so is
very efficient.

3)  The spark ignited engine requires a close to stoichiometric mixture, so
must throttle the mixture from near atmospheric to very small values to
control power.  The butterfly throttle is a MAJOR waster of power.

4)  Can't one of you clever gals or guys invent a "working throttle" (like
the exhaust turbo) to recycle some of this energy?  How much energy is it to
take the mixture from a power producing near atmospheric pressure to a power
wasting 25 inches vacuum?  (Probably related to R ln (p2/p1)).

Too busy to figure it myself...

Cheers,     TOM REED
