High pressure and high temperatures can most certainly change h20 in to h2 and O2. but there is not a chance in hell that the engine in your car could do it.

the pipe glows red because when steam turns back into water it release about 2 kilojoules of heat into the air or the closest surface (your exhaust)

as for the water vs atf problem. why dont you guys do the atf trick to dissolve the carbon and then run water through it to clean out the excess and the cats.

you arent supposed to run the water through for more than 1 minute at intervals.

i seriously doubt that you could release a chunk of carbon from your engine that would prop up an apex seal (since it is already in there) it isnt like you have gravel size chunks in there

i meant 2 kilojoules of heat per cc of water so that leaves us at about 4000 kilojoules of potential heat right there with 2 liters of wter. but steam can get hotter than 212 degrees. it can even get as hot as the hottest part of the flame in your chambers.

it carries heat very well through air and distributes it very well onto metal. so basically after your pipes reach boiling point which shouldnt take too long. you pretty much just set your pipes on fire for three minutes. i wonder what it did to other parts in your car?

so take it easy with the water.

Well I tried the H2O trick for the hell of it.......YES! I didn't blow my motor doing it. Dunno if it helped I think i fouled my plugs but sure was fun seeing the steam come out the rear of the car.

Waiting for my set of Magnacor 10mm to come in to change the plugs. For some reason my Racing Beat ones were arching.

For all of you that doubt the ATF and or H2O treatments-

A highly respectable rotary mechanic, Rob Golden of Pineapple Racing, recommended the H20 treatment. I'm sure if it were going to harm your engine, then he wouldn't recommend it. Besides, noone is doing things JUST to work on their car. If you really believe that, then I'll give you a call next time I need to "work on my car," and you can come do it, because I have many other things I could be doing. I think people just want their cars to run right. Ever thought of that? Why don't you guys spend more time encouraging people rather than making them feel stupid or worthless. Sorry if everyone else on the board isn't a perfect rotary mechanic with the skills (or time) to pull an engine and clean it perfectly free of carbon, but by all means if you are volunteering to do mine for free, you are MORE than welcome.

PEACE,
Derek

I have to agree in all my dealings with rob he has never given bad advice nor for as long as I've heard about pineapple have I ever heard anything bad, that says something.

Cat is not glowing b/c steam turns back to water. The reason the cat and pipes glow is because the water in the combustion chamber prevents maximum combustion and/or slows it down in the chamber. As the partly combusted mixture pass thru the cat it combusts even more. To prevent the car from stalling with the water treatment more throttle is applied which = more partly burnt mixtures the cat need to burn. I can make my cat and pipe glow just by retarding the ignition timing b/c the mixture is burning alot later....to the point that most of it combusts in the pipe.

someone said to use the brake booster hose for water on a 1st gen? i have a 12A that runs like **** will this help? how long should i keep the atf in the engine for before starting it up? also i read some where that i should put about an oz of atf in the lower spark plug hole and turn the engine 1 time around then do it 2 more times on each rotor(3 times each) is that right?

no...... if it were combusing inside your exhaust you would have detonation and loud pops coming out of the exhaust pipe. i dont care how slow water makes it burn. there would be detonations in there. no spark no fire. it gets hotter because the steam is carrying all of the heat from the chambers into the exhaust pipes. h2o carries heat a whole lot better than air (humidity......) when you retard the ignition you are just getting hotter exhaust. there is no combusion in you exhaust pipe Mr. Afterburner

The Internet has so much garbage , its getting more difficult to sift through. I thought some rotary fans were smarter than this in this forum as far as engine operation...no offense.

How does burning air/fuel mixture detonate in the exhaust system? You don't even know what the term detonate means. "Definition: An unwanted explosion of the air/fuel mixture in the combustion chamber caused by excess heat and compression, advanced timing, or an overly lean mixture. Also referred to as "ping"." It may cause some backfires(poping) if the mixture is rich enough.

You've heard of water injection for high boost high horspower engines...right "Mr Think he knows how engines operate"? If i'm a betting man, I bet you didn't. And if you did, you couldn't correlate it into this situation for some odd reason. Guess what the water injection is primarily used for those high boost engines? " Water injection decreases the possibility of detonation by lowering the combustion chamber temperatures and increasing the effective "octane" of the fuel." http://www.dawesdevices.com/water.html I can site many more articles from books, websites and newsgroups. But do your own research. Since this is water treatment with not much boost, the water will almost drown the combustion process to the point that alot of throttle needs to be used to keep the engine running. Therefore, the cat has to do a lot if not too much(melt down) of the work to burn the unburnt fuel mixture which it is designed to do.

Yeah water carries alot of heat....but thats not the reason the cat and pipe glows in this situation. Guess what the byproduct of your car's exhaust is if it was running efficiently....H20 and CO2. So I'm assuming, in your wacked out logic, that your saying....add more water=more heat. LOL

There isnt combustion in the exhaust? Wrong, there is combustion in the exhaust if ignition is retarded enough with the right air/fuel mixture. Why would EGT's be higher with retarded ignition timing?....hmmmm...THINK! You are probably thinking combustion is an explosion in an engine or exhaust system. Its not, its a rate of burning. Since its out of the relatively highpressure combustion chamber it will burn as a blue flame(which means good air/fuel ratio using gasoline) alot slower than if it were in the combustion chamber. I've seen it done from rotaries to Formula 1 V10 engines(yes they use gasoline) engaging their traction control system screaming at 18000rpms with relatively short exhaust systems. The yellow flames you see in some race cars and rotories that stream or pop out is when an ultra rich mixture hits the air outside of the hot exhaust where it burns unevenly.

Mr Mguire's comment on water combusting in the engine is completely 100% false. Logically speaking, if that were so we wouldn't need gasoline for fuel. We would have already created an ultra high compression motor(kinda like a diesel motor) where the compression stroke would compress the water vapor and air mixture to the point of combustion....LOLOLOL. Water is such a stable substance that you would need electricity to break its chemical bond apart into H and O. Its Hydrogen bond is much easier to break which are basically water molecules(steam, water vapor) still H20.

Sorry about that. I'm not trying to start a fight or anything. I have an RX7 too. It just bugs me that some of the obviously wrong ideas seem right to some people. And they try to spread it and its like a disease. If only this forum had more informed users.

you must have taken resource physics. high pressure and heat can be used to split h2o into h2 and o2. but the power required to do that is more than the power of combustion when the two elements combine again. get it right

and if you went to school in redville yeah your dictionary would probably tell you that detonation is a word that refers only to an engine. but in the intelligent world we know it as a forceful chymical reaction between two or more combustible elements. so you are saying if i "detonate" a missile that is "Definition: An unwanted explosion of the air/fuel mixture in the combustion chamber caused by excess heat and compression, advanced timing, or an overly lean mixture. Also referred to as "ping"

dont be a dumb@$$ yes i have heard of water injection and i know what it does. i dont see any glowing tailpipes there though.

oh and the reason a normally working exhaust will give off water is because of the catalytic CONVERTER.

MOST of the time you see flames shooting out the rear of high power cars is due to a "detonation" that is placed right in front of the exhaust entrance to a turbo between shifts in order to get rid of turbo lag inbetween gears.


play on Mr Hon-duh. get a websters dictionary instead of your shop manual and catch up with the rest of the world

I never said that high pressure and heat can't split H2O.

What has detonating a missle have anything to do with unwanted detonation in the internal combustion engine in an RX7 forum? Stick with the subject!! Now that is being inteligent. They both use combustible materials. One term of detonation is wanted explosion the other is unwanted explosion in a car engine. Get it? Why are you trying to change the subject we are arguing about? What is your point? I gave the appropriate definition for detonation.

Yeah you heard of water injection but never fully comprehened on what it was all about.

Your last statement about flames is only partly true. I can name you many high horsepower cars that belch yellow flames between shifts....but...THEY ARE NOT TURBO! I'm not saying some racing turbo cars, like rally cars, do not have anti lag systems that you described either.

Oh and in theoretical terms you don't need a cat converter for H2O and CO2 to be produced. But in the real world we need it and that is why we have it. Research it.

Hahaha...making fun of me owning a hon-duh doesn't change the fact that your still a looooooser.

i was trying to explain it simply so you would understand. when i said detonation the first time. i wasnt talking about detonation in the engine. i was talking about an explosion ANY EXPLOSION d o y o u u n d e r s t a n d . . . . . .

oh i understand about water injection.. fully. but that does not cause combustion in the pipes it just cools the incoming air so it doesnt ignit due to high temps and that too causes more heat to build up in the pipes because of the addition of water. but not as much as with the water treatment.

yes cars without anti-lag systems do belch flames and that is because of the ultra high mixture like you said. but this is not happening when you suck water into your engineif it were to happen you would see it at the tailpipe where it hits the air. this is why i said most


(((Oh and in theoretical terms you don't need a cat converter for H2O and CO2 to be produced. But in the real world we need it and that is why we have it. Research it. )))

there are a lot of things that will theoreticlally work but not n reality... so what

(((Mr Mguire's comment on water combusting in the engine is completely 100% false)))

yes his statement about it in the engine was false. but he was right that high pressure and heat can do that... that is al i was saying

(((Hahaha...making fun of me owning a hon-duh doesn't change the fact that your still a looooooser.)))

is that the best you can do... calling me a loser... you sound like you are 5.... grow up diaper boy

Well since you think your so intelligent you should have no problem deducing which detonation I was refering to in an engine example. Obviously your not too intelligent. You would think of missles exploding when I say my car's engine is detonating...LOL That is some messed up logic you have there.

Your making stuff up!! Why? I never said water injection causes combustion in the pipes! Water treatment will almost drown the combustion process to a point that alot of throttle needs to be used to keep the engine running. In other words its misfiring, if you can't figure it out. Again, the partially spent air/fuel mixture has to pass through the catalytic converter. The catalytic converter's job is to basically burn air/fuel mixtures and partially burnt mixtures that make it out of the engine. Once again, since the water treatment causes the car to misfire more throttle needs to be applied to keep it running. More throttle in the water treatment example equals more unburnt air/fuel mixtures the catalytic converter has burn. Same effect on the catalytic converter can be achieved by unplugging 2 spark plugs form one rotor or in a 4 cyl and run the motors It might be able to run on one rotor, or in the 4cyl case, 2 pistons with a lot of throttle applied. The catalytic converter will glow bright red. Keep it up and you will melt the converter.

There you go again....making up stuff. When did I say flames belch when the engine is sucking water? Enlighten me? You taking certain illegal drugs we should know about? I'm sorry, if this isnt induced by drugs you should learn to read a little better. And try to understand what you read too.

CO2 and H2O are in reality produced in the exhaust even with out the catalytic converter. In theory ONLY CO2 and H2O would be produced. Does that make it more clear for you?

I think the only person that needs to grow up is you. You can't accept the fact that you have no argument here...so you resort to making up stuff that I clearly did not say so you can try and escape. You should be an author of a science fiction film or something....like the X-Files. Sometimes that **** doesn't make any sense. With your imagination skills I'm sure you'll fit in.

Make sure you stay focused at the task of rereading my posts at least 5 time b/c it appears you have ADD. And remember try not to make stuff up next time. You look like a fool when you do you moron.

alright i am just gonna say one thing and then i am done. you are just too stupid to argue with

i was the first person to mention detonation. and i was explaining what I MEANT when i said it.

alright i am done with this

I wish they did shut it down from the time Mr Impezza started making up stuff and creating off topic arguments. I come here to discuss about useful information needed for my 88 rx7 turbo, so I start browsing the forums in here. Only to hear false statements from some people related to engine operation. And no one seems to want to argue some of those statements.

On the contrary...your the not so intelligent one. Why would we need a definition of a missle detonation in a discussion about a car's engine detonation? And arguing with you who makes up stuff is not too productive, unfortunately.

Yeah thats because you have no legit argument. Get over it. Finished yet? Where are the moderators when you need them? They need to lock this thread before any more baseless comments are produced.
