Water Injection

[Robert Harris]

When you grow up enough to get tired of the HRM and other myths,
misinformation, conjecture, hype, anti-hype and general bullshit you might
just want to read up on what your tax payer dollars paid for on the subject
when lives were dependent upon the advantages it provides.

Check out the NACA report server - there are literally dozens of reports here
that were created using test engines, dynos etc specifically testing to
destruction various facets of engine design including water injection.

Some generals from the testing.   Water injection works as an internal coolant
- absorbing energy from both the charge and the cylinder.  Works well enough
that at high levels greatly reduces the heat lost to the jacket.  Fact - read
the reports.

Water injection replaces excess fuel used for coolant with little power change
( favoring water injection ) right down to about stoic.  Fact - read the
reports again.

Excess fuel ( Rich mixture ) is used primarily for charge/internal coolant.
Power output water vs rich about the same up to the detontation limit for
fuel.   Water however, can be used to much higher limits and allows major
increases in power over fuel because far more charge at much higher pressures
can be consumed in a cylinder.

Upper limit for water injection testing was limited not by combustion, but by
severe water contamination of the lubricating oil.  

The NACA stuff is kind of hard to accept.  Silly arsed bastards didn't use
computers or math models - they actually built engines, tested them to
destruction and recorded their results.  Oh - silly me - that's primary
research.

If you worship the Taylors, did you know they did the research for most of
their books at NACA and you can get copies of the original research?  Same for
most of the other prominent writers.  You can read the sound bites in Heywood
or read the research at NACA.

Pleasant reading for the few - the rest - enjoy the myths.
