Can water extend fuel efficiency?

Question

It seems that nobody believes the last try at this so I will post the web page that gives the full details. You tell me what is happening when you do this experiment.

Answer 1

Theoretically you can adjust the rate at which gasoline burns in an engine with a water spray.

With todays computers and fuel injection systems it might be possible to make this actually work.

It has been tried many times before. Mostly where I have seen these devices is as penney stock scams or as cheap add on devices that do not have the ability to work.

In the past this has just been used as a cheap device to make money for a promoter because it is a good story and theoretically it should work with a properly designed system.

The way something like this would work is to increase the transfer of energy to the piston to do useful work. Under many conditions the gasoline burns too fast to transfer the optimum amount of energy to the piston.

Under particular load conditions when the gasoline needs to burn a little slower, a small amount of water injected into the fuel stream will slow the rate of combustion enough to make it possible to transfer a greater portion of the energy to the piston.

You need very good sensors, a good computer and a good water injection system to detect the periods of load where it would be more efficient to slow the rate of burn and inject exactly the right amount of water to accomplish that.

I do question the results that you report however. As you describe the design of your system it will not give you the efficiency increases that you describe.

Your initial mileage results that you report for that car do seem low.

I suspect that any increases that you saw in mileage were from tuning up your car in the process of doing this experiment.

Answer 2

Your actually running a steam engine . When the water hits the hot piston it turns to steam creating pressure .

Answer 3

Be careful of your sources. If you do a WHOIS, you'll see that this was posted by the infamous John Greenwood. Here's another one of his sites.

You will notice that there is no real data presented, no discussion of how mileage was measured, no real scientific study what so ever. This all screams out SCAM.
