Hot Water Injection

I heard about hot water injection just last Saturday. I've never heard of it before. Can anybody shed some light on it. I can't remember who did it but it gained horsepower on the dyno. All I can think is that they ran a tube by the manifold to heat the water up then inject it. They would have to run a lot more water.

Water injection has a number of benefits.

Liquid water into vapor water has a large latent heat (amount of energy required to vaporize it). So if you've got a hot burning engine, injecting water will help cool it off some. These modern 4 cylinder rice burners that kids "tune" to high rpms with turbos and nitrous run REALLY HOT. They can start to melt pistons and valves and things. Inject a little liquid water and viola cooler engine. I've seen a tuner company advertising kits to add on to the car engines.

Another feature of injecting water is the large volume change of vaporization. This is the feature that steam engines work off of. I'm not sure if it is more or less than the volume change of combustion for gasoline (but I'd guess it's less) but it is still substantial enough that it does help "push the pistons down".

One issue is how to efficiently atomize (nebulize) the liquid water into little droplets that will get sucked into the cylinder. That is where the art lies. If you atomize it too small, then it evaporates and you only get the cooling benefits of the water. If you don't atomize it small enough then you don't get as efficient coolling of the cylinder.

If you are running high rpm, compression, turbo'd, etc... water might help you from burning out your engine.

My John Deere D will allow injection of water from the radiator into one of the cylinders. It increases the compression. Many of the military airplanes were able to do it also.

The water injection system on the "D" wasn't used to increase compression. It was used to cool the intake air charge down some in order to combat detonation. The distillate and other heavy fuels all-fuel "D"s were designed to burn had very low octane ratings, and the engines could be prone to preignition at the high engine temps needed to burn those fuels efficiently, and under heavy loads.
