    Water injection and alcohol fuel

    Pat, At the time of the tests of the injected Ethanol/water in the Dodge 318's, I adjusted the flow into the intake manifold at high RPM and adjusted it rich until it stumbled giving it the max alcohol/water that it could handle in addition to the preset gasoline, then leaned that alcohol/water...

    Water injection and alcohol fuel

    Thanks Pat, that pretty much sums up my construction, operation of a still, building of an alcohol engine and the experiments afterwards on my DOE grant. I tried ethanol from wheat and from corn and both worked well in my engine. As for cost in operation of a still to make ethanol, I didn't...

    Water injection and alcohol fuel

    Many diesel truck engines on the over the road trucks use a compressed air powered starter motors but I directly inject compressed air into the combustion chamber to spin the engine over to start this engine. I designed and built a air distributor keyed to the camshaft and an engage and...

    Water injection and alcohol fuel

    btrueblood, I ruled out "fuels" like that due to cost. Can you picture gas stations/markets with liquid Nitrogen in stock for customers and how much would that cost for a fill up? That would get a better range then just a compressed air tank but there is no system set up to refill. I went at it...

    Water injection and alcohol fuel

    Sorry maxc, I had no equipment to monitor flow rate and it was always ethanol that I had made with my still. All I did was done with standard mechanics tools. The flow rate was adjusted to a high rate while at a high throttle opening until the engine stumbled and then leaned out just enough to...

    Water injection and alcohol fuel

    Hemi, My tests of the two Dodge 318 trucks was done with the engines on gasoline and no alterations at all were made in timing nor fuel mixture. So nothing was changed except the addition of a small volume of 100 proof alcohol to the intake. I first thought it could be the addition of a small...

    Water injection and alcohol fuel

    Hemi, The wright engine lost 30 brake horse power power on one cylinder by injection of water/alcohol and that resulted in a loss of 35% of the power that #10 cylinder normally produced? Is that true? Do you have any info on what the water/alcohol ratio was (proof)? also what volume of alcohol...

    Water injection and alcohol fuel

    Pat & Azmios, I did not have a condenser on either the alcohol engine nor on the two Dodge 318 engines. But the thought did cross my mind and on a third engine that only made it on the drawing board I did consider it. I wanted to build a small SI engine the run two cylinders on gasoline slightly...

    Water injection and alcohol fuel

    Pat, doesn't that confirm my tests on my straight 170 proof ethanol engine maintaining power with 15% content of water when compared to that same engine tests running on 200 proof? With my 170 proof I had lost 15% of my fuel and using water to replace that 15% should have lost some heat...

    Water injection and alcohol fuel

    I have a question for all of you as I have no engineering degree and ask it out of practical applications. I noted that in the mid 70's on, when emission control was applied to auto engines, the combustion chamber temperatures climbed higher (thus burning the Nitrogen and producing NOx)...

    Water injection and alcohol fuel

    Pat, you mean that you can heat air and get just as much power as heating water and turning it into steam? I didn't know that. Why didn't steam engines just heat the air and not bother with the water? Does heating air give you the same expansion power as turning water to steam? That still...

    Water injection and alcohol fuel

    Thanks again azmios, for the clear explanation. I didn't know why it worked, I just know for sure that it does work and works well from my experiments and practical application. Those in doubt need to actually try it. Slim3

    Water injection and alcohol fuel

    Thanks azmios, I will try to find those SAE papers and read them. I am about to finish up my direct injected compressed air starting system on my show car and plan to enter it in the Oct 13th British car show in Nashville.

    Water injection and alcohol fuel

    Lots of great information bouncing around here. I am now studying compressed air as a power source for an engine. I have built a Olds 215 to start on direct injected compressed air and it works well. My next project is a full operating compressed air engine. However to expect any range I had to...

    Water injection and alcohol fuel

    Thanks Thrusthefence, that article by Pratt & Whitney was informative and the Piston engine part clearly explains why I got more performance from the two Dodge engines by adding water injection. I was only thinking of the steam produced and didn't think about the fact that the latent heat of...
