<br /><br />About the only thing that water injection will clean (real well) are the piston tops and combustion chambers. The water (vapor) blasts deposits off, it doesn't desolve anything. Witness a piston top/combustion chamber on a cylinder that has had a head gasket coolant leak. It would be sparkling clean.<br /><br />Come to think of it, why couldn't you decarb an engine by using a fine mist down the carb, using a spray bottle, when the engine is up to temp and at a moderate throttle?Another old Indian trick was to dribble a quart of automatic trans. fluid down the carb. to knock off all the deposits that 'grew' in older engines.<br /><br />On modern engines, you shouldn't have to do any of that. <br /><br />Unleaded gas. doesn't make the deposits you used to see in years gone by, the valve stem seals, and the oil itself is better now.<br /><br />Between the modern unleaded & detergent fuels and newer detergent oils, They don't make the 'crude' that used to grow on piston domes and around valve stems and choke a engine like the old days. <br /><br />Ed.
I figure,,,,, You could, and it'd work great.<br /><br />But at todays prices, hardly anybody can afford for a decent sized engine to run so rich for long enough to need it......
I just took a bunch of heat for saying the above. In 1980 I used a vacumm controlled vapor injection sytem on my 1980 Audi Turbo. You thought you were riding in the space shuttle when that turbo kicked in. Along about '84 I had to pull the aluminum head, due to a striped spark plug thread. Everything inside looked like it came off the parts shelf.
.<br />Nitrous oxide is an oxygen beaing fuel. in and of itself is non flammable. oxygen aids combustion but is not a flammable gas. nitrogen is an inert gas that really reacts with nothing. that is why with Nitrosoxide extra fuel must be injected or a super leanout and melted parts are assured.<br /> Nitrous injection has been about since the 20's the germans used a lot of it in aircraft for emergency power.<br /> back in the 60's chysler had a water injection on some large engines. an internal combustion engine works on a principle of expanding gases. water when heated expands a tremendous amount. for antiknock properties it was injected at various engine vacums(loads) and would supress knock and add power due to the expansion of the water. I have used both to increase power and supress spark. No2 if done correctly will increase combustion pressures but actually lower temps due to the fact of extra fuel and the nitrogen does not burn.<br /> its something I used to play with a lot but quit years ago. we ran methonal and nitromethane in a 427 for a long time. some we learned the hardway. but we found with careful calculations on paper and starting out on the side of caution a 671 with 2 780 and methanol with a small percentage of nitro methane can make a bit of power. there again. nitromethane is a combination of reactive and inert substances. but its an oxygen bearing fuel that is flammable. the heat rating of methanol is similar to gasoline. the octane of methanol is 100 it takes 4.5 parts of methanol to one part air for correct burn. it takes about 14 to one for gasoline. so if you think your gas milage bites, try methanol. <br />sometimes, usually when enjoying a cool beverage< I almost think about getting back into HP work. but usually by morning I am over it . thats all<br /> the whole point is about maximizing how much air you can get in and out without melting anything. the hotter the gas the more the volume of expansion. all the way up till something melts. thats the difference between a welding mix and a cutting mix.<br /> I saw to many melted engines when people tried the NO2 trick cause they failed to insure the extra fuel. not because of the NO2 itself. but common legend has it otherwise so I quit trying to assist .<br /> and yes the old Gnome rotary engines were a work of art. the mostcommon was a 5cyl version with external pushrods and rockers and the crank was fixed to the firewall and the cylinder assy rotated around. made for some odd torque and vibration characteristics <br />was an interesting study though. I wote a senior paper in english about the design,construction and use. I wish I knew where it went.<br /> got an A on it mostly cause the teacher had no clue but it looked good with plenty of footnotes .<br /> goes back to the book I mentioned <br /> Motor auto engines and electrical systems. it should be a must read for any novice.<br /> but there are many books on internal combustion engines,and fuels and fuel systems.<br /> acetone and compressed air will make a lot of power as well but its difficult to handle and the vapor pressure makes it unsuitable for common use but its been tried.<br /> but I grew up with this. my father owned a wrecking yard and raced english sports cars. he was also a machinist with the nuclear program at newport news shipbuilding. he supervised the first refueling of the USS Enterprise and wrote most of the procedures. I also grew up broke <br /> did not take long to realize that "speed cost money,how fast ya wanna go".<br /> first thing to do with any hop up procedure is to set goals for speed and RPM. then you have to factor in weight, then fuel type then you can start ploting gear ratios and such. I was lucky that my father was also an engineer and some of the car clubs around the DFW area had some as well. gave me access to all kinds of formulas. I could not afford to randomly buy stuff to go fast. I learned early that make it work on paper and it will be very close in reality. most times .<br /> but in any endeavor always remember the basics. the more high tech the engine controls the more important the basics become. the high tech rarely fails but it can compensate for low tech failures somewhat.<br /> but I have read a lot of smokeys writings along with duntov's, shellbys and a host of others. machines have always fascinated me. so I do the boat thing now cause its about the last place where you can run an engine for hours at its rated horsepower without getting a ticket .<br /> goes back to my bible<br /> motors auto engines and electrical. the laws of physics dictates how it all works. just the control signals change.<br />just like gears is gears. dont care if its in a watch, a clock, a differential, a lower or upper unit or anything else. gears is gears and they all have physical limitations and operating specifications.
