check out this fella atb and read what he is doing with water in the fuel to make a more complete burning. it is a different style of engine but does it apply to our engines?

is this good for us and the ip? i thought water in the fuel was bad.

Not all water injection is bad. Back during the big war, B-52G Stratofortress bombers would inject water into the engines running on JP4 fuel. Lotsa black smoke and extreme horsepower. This was done for "heavy" take offs, like loaded with bombs.

Thanks, but I'll keep all water out of my engine and fuel system.

Water injection has been tried by the towing crowd over the years. A decent system will lower EGT's but not really increase hp any significant amount. The main problem is a lack of good high pressure 12v water pumps and the fact that you use a lot of water when the system is in heavy use. Like 12gallons every tank of fuel. Finding clean water to put in the tank while on the road can be an issue as can freezing in winter. The other issue is finding space for a 10+gallon water tank. Not a big deal if you tow and have a whole bed to mount a tank in.... RT

little back in the day, 1920's, John Deere used water injection on there model D, this was to keep pinging down while burning kero. The water was fed right from the water jacket from the block, it was controled by a rod and lever, it was up to the operator when to open the valve. I have heard this worked pretty well, much like on the WW II bombers. I believe back in the 70's water injecton was more popular and was sold as kits. I think you bought some sort of solution that was "injected" not just water. But, I don't think water would do much good in a diesel, the water would never enter the main fuel system, it would be injected in the manifold its self, so in turn I don't think it would do any good, and probably more harm.

Having lived a sheltered life I never took a mercedes injection pump apart. Guess in a pinch the wife would do it if I admitted no knowledge. Anyways think they are a piston pump and was led to believe water acts simular to sandpaper in those bores. But you have to be careful of what you hear as I am still trying to get past the two can live as cheap as one the wife told me years ago.

My grandfather is a life long john deere mechanic,

he was telling me about this..

It seems that they used to run there old diesels on crude oil, and they used water injection to get it to run right like you stated. You adjusted it until it would run right, and he said that they could run all day long on crude oil and water, but he did state that the water was injected into the intake not in throught the fuel.

The 1955 Mercedes SLR with which Stirling Moss won the Mille Miglia had water injection ...

Water injection is OK in gassers. It's used to keep the pinging down especially when using low octane fuels. My guess was the SLR had a very high compression engine and possibly the fuels available then were not high enough in octane to get maximum output.

Yup, he was right, you can almost burn anything in an old John Deere (all-fule) started on gas, then when up to about 195, you could run on diesel if you wanted too. The water was injected into the manifold, and kept pre-ignition from happening when pulling that 3 bottom plow in hard clay!! If you like the sound of a mercedes diesel run, you should hear an old JD 2 clyinder run, nothing runs like a Deere!

A guy over on thedieselstop.com (forum for ford 7.3 IDI diesels) blew up his engine after installing a water injection setup. It was the hot new mod until that happened...

Had a gas '79 turbo Scirocco where I ran water injection. Allowed a few more pounds of boost without detonation. Just had an oversize windshield washer tank and pump. Set it up with a solenoid and presure switch to come in at say 10psi or so. In the winter I ran either a water ethanol mix or windshield washer fluid. Ever see spark plugs turn blue? Evaporation of the water absorbs some of the heat plus the water interferes with the combustion so that also lowers the combustion temp. Might work to get your NOX readings down for emissions test? Not sure what an O2 sensor would think about steam coming by it.

Hey,
When I was in Daytona last weekend I had an interesting conversation with someone. He was telling me that there were new engines that used water in fuel system.
Apparently it kept engine temps down and prevented the valves from overheating. He said it was used in NOX systems also.

Of course this is all heresay because I have never seen it or know anything about it. Just thought it was interesting.

Yeah, he also showed me a deere that had a v-4 starting engine for the main 2 cylinder engine, he even ran it for me, fun stuff!

I have driven diesel deeres since the age of around 8. Hes the one that got me hooked on diesels.
