ETHANOL PRODUCER'S DATA BASE

Simplicity in Applied technology

Water Injection origins

  • Water injection was evaluated scientifically in the 1930's by H. Ricardo who demonstrated that one can basically double the power output of an engine using water/methanol.
  • The first widespread use was during WWII on supercharged and turbocharged aircraft. In 1942, the German Luftwaffe increased the horsepower of the Focke-Wulf 190D-9 fighter aircraft from 1776HP to 2240HP using 50/50% water/methanol injection.
  • The allies soon followed by fitting the P51 Mustang and other high performance aircraft with water/methanol injection.
  • Following the war, the turboprop aircraft industry used water/methanol injection and called it the “automatic power reserve system (APR)” for use in hot or high altitude take off.
  • It surfaced again in the 60's when GM used a system on the OEM turbo Corvair.
  • It was used effectively in Formula 1 before being banned for adding too much power.
  • The latest competitive use is in World Rally Racing (WRC) where virtually all teams use it in some form and in diesel truck/tractor pulling competition.
  • It is important to note that in the fall of 2004, the long standing world record in the quarter mile for diesels was broken twice (now 7.98 sec) by two different vehicles; both using the Boost Cooler® water/methanol injection system by Snow Performance.

 

Water Injection

  • Water injection is not a new subject, in fact, it was well researched by the NACA ( NASA today)for military applications and use succesfully during World War Il.
  • The military made extensive use of water injection in high performance piston aircraft engines, and in truck engines.
  • Later, water injection was used by both civilian and military engines to provide extra power.
  • Even today, water injection systems can be built and installed in the most modern of automobiles.
  • The fact is that, within certain limits, these systems actually do increase power.
    • The latent heat of vaporization for gasoline is about 140 Btu/lb.
    • The latent heat of vaporization for ethanol   is about 361 Btu/lb.
    • The latent heat of vaporization for water      is about 700 Btu/lb.
  • Therefore, if a little water is injected into the air intake stream in the form of an ultra-fine mist, ( or in the form of low temperature steam ) the latent heat of the water will cool the charge and increase volumetric efficiency of the fuel mixture.
  • In addition, when the charge is fired in the cylinder, the water will turn to high-pressure steam and provide additional power due to the pressure exerted by the steam.
  • There are definite limits, to the water content of the intake air.
  • Too much will cause excessive cooling and misfiring.

Ron Novak's Do-It-Yourself Water Injection System

You can improve your car engine's starting ability, pickup, and fuel economy by constructing a homemade water injection system -- for a total cost of under five dollars! And you'll spend that small amount of money (heck, it takes more cash than that to buy one tank of gas nowadays!) entirely on parts -- because all the information you'll need to "inject" your own auto is right here in this article! ( Original article Mother earth 1979 )


Corrected flawed 1979 Drawing

Gilles,
Something I noticed in the diagram at your web page that might cause problems in the existing vacuum system.
If you cut the line as shown, and install the needle valve in series with other vacuum-operated devices, they may not perform properly because of the restriction. Perhaps it might be better to locate the valve on the branch of the tee?
Regards,
Ralph

Here is my rendition of the original 1979 Diagram with Ralph's recommendations.
