Hello List,
Introduction of water vapor into a petrochemical internal combustion engine
does improve performance (improved burning of fuel). If my memory serves me
right, this was used during World War II in airplanes to enhance their
performance. There are two schools of thought as to why:
1. The evaporating water/alcohol cools the intake air and makes the air
more condensed (more molecules of oxygen)as it is sucked into the combustion
chamber. (Note the alcohol prevents water from freezing due to the venturi
effect or sometimes referred to as vapor lock).
2. The water (H2O) introduced into the chemical mixture of fuel (Hydro
Carbons) and air (Oxygen) performs a more efficient chemical reaction
(burning) solution.
I was not a good student (chemical or otherwise) so I don't know which is
right if any. In the early 1970's as gas went from $0.25 to $0.50 per
gallon, I helped a friend of mine install a water injector for a carburated
gas engine. There was improved performance, but fuel mileage improvement
was nominal since the big 455 Cubic Inch V-8, four barrel carburator was
only getting 11-12 miles per gallon either way.
Regards,
Mark Gill
