Thread: water injection

    water injection

    Fellow Riders,

    Now that Winter has come to the Minnesota Tundra, Riding will be selective. I am curious as if anyone has tried Water Injection into their Steeds. I have read of a fellow that bolted a small engine intake to the exhaust of another small engine, proving that the fuel is wasted due to having the second engine actually running on the exhaust. Or that the gasoline is also used to COOL the engine, so the fellow ( George Wiseman) tweaked the fuel delivery less into an engine and used water to cool it.

    I have heard stories from farmers that would use water to cool their tractors,

    Anyway.... where is the nay sayers to rebuttle my arguemnet?

    I have heard of this some time ago......more complicated than I could get involved with. We used to use water down the carburetor to shake the carbon loose. I canít say it really helped.

    Tim -

    Here's some discussion of a system a number of years ago:

    Urban legends, lies and scams I tell you!
    Seriously, there is a lot of misconception going around about combustion, some from ignorance and some intentional tell you stuff. Water injection made sense in WW2 fighters where max power was literally a life saver, and engine metallurgy had a lot to learn. It cooled the cylinder charge and prevented preignition.
    If you are suffering with preignition on a modern engine today, you have some other problem causing it.
    Gasoline introduction into a hot cylinder does have a cooling effect, especially in direct injection cars, but the evaporated fuel isn't lost, it's simply vaporized and eventually combusted. Using less fuel and cooling the cylinder with water will simply result in less power because of the reduced fuel. You will also likely screw up the mixture ratio which is critical for bother engine performance, cleanliness, and proper catalytic converter operation.
