they most certainly did not put it out as the main componant of the experments. to clarify for you, there is a small increase in the dwell time at TDC. the increase of the burn at TDC is longer and thus a small increase in thermodynamic efficiency is realized. it is very small so I didn`t dwell on the thermodyamic part of it compaired to the entire increase.

No computer comes with a built in spell checker!!!!! It is a component of the program that does or does not have it. Obvesously my news reader does not have one. unlike some anal retentives I focus on quick thought transfer not perfection on spelling. This is not exactly a scientific forum. KB

apparently you missed the part about "full expansion" and don't understand why that was being pursued.

no, it's not "obvious" that it doesn't have one. especially when they're free and easily available from any other competent news client.

do you worry about accuracy when driving? i mean, it's only a few feet between you and an oncoming vehicle. what about accuracy from your bank when they're sending your monthly statement. would a few hundred dollars rounded down be ok?

no, it's "tech". car's wouldn't run without the science that goes into the "tech".

Virtually every engine used to provide forward motion converts energy into a rotary motion. So what?

The power output is usually defined by the the amount of energy that is transformed. A turbine functions well when the engine speed does not change much. A rotary and other piston type engines are designed to run at varying speeds and to change speeds relatively quickly.
