Tried to clean the engine by injecting water...

[Enthalpy]

Combustion creates tremendous amounts of water. Just look at the condensed water pouring out of a cold engine in the winter.

Water injection rates pale in comparison.

Pistons are aluminum... they don't rust. Rings are steel... they do.

Hot Engine + Water + Steel Rings = Nothing but evaporation...

It takes a good deal of water to actually cause fracture by thermal expansion - way more than you engine will ingest without hydrolocking. I've run way to big of jets in WI setups, and has it ever hurt anything? Nope. Engine will not make good power, but I get really clean combustion chambers afterwards!

your talking about water from the tailpipe...?

thats from your catalyst... its actually a good sign your cat is working...

yea this has gotten outta control... from the beggining i said water works in controlled amounts... and you risk alot more damage then if you used an alternative... i suggested ATF... because i've seen fracture by water

I think I forgot the /sarcasm.

Water injection has been used for decades. It is safe. If we're going down the "temperature differential" path...ATF and water injection would have the same likelihood of cracking a piston.

As for steam coming from a tailpipe...

When you turn off your car, the exhaust is warm. As it cools down, water condenses in it. When you start your car back up, it gets hot and evaporates and comes out in the form of steam. It happens whether or not you have a cat.

This one time it was really foggy out and my engine locked up, sucks, true story.

Here are the two biggest risks of injecting anything into a gunky old engine (as all of ours are gunky old engines by now.)

1. A big chunk of carbon may break off and damage an exhaust valve/seat.

2. Chunks of crap that break off may not get vaporized and can clog up your cat.

As such...if you decide to do this, you ought to take it slow at first so you don't dislodge any huge chunks of crap all at once.

You sir, are an idiot. In order to atomize a liquid, you must inject it under pressure. Adding a few small drops into the intake will not do this. What you are talking about is evaporation.

ATF is a high temp lubricant. it is designed to handle heat.

Thermal shock does not occur here. The fuel is cool, the air is cool. Cool water injected in small amounts at high pressure will not thermally shock the piston or anything else inside the motor.

Um, wrong.

OK, so you have been an idiot for at least several years. Great, you have narrowed down the window. The trick now is to eliminate your stupidity and join the rational world.

Take your "superior, know-it-all" attitude and go away. Maybe go to the honda forums and see if they realize how stupid you are too.

[Mister2.2]

Well it's a good discussion aside from the name calling.

I wouldn't be that hard on him. If everybody followed that lead, the "OC" would have like 20 members. I find his posts enjoyable.

I doubt they would.

Good One!

...So you are saying cars didn't spit significant amounts of water before the days of a cat?

The majority comes from combustion. A small amount comes from a catalyzed reaction. Imagine the cat temp if the majority came from the cat! OI!

http://www.answers.com/topic/atomization

Maybe you should read the end article that explains how atomization is the break up of droplets...

I said too much liquid will not atomize and form a pool in your manifold
Which is true

and you say you have to inject under pressure... so at the beggining of this post when i said this process needed to be done at 2,000 rpms... when manifold pressure is high and vacuum is low... what didn't you understand...?

I bolded it so maybe you can see it better... and for the rest of you i got something for you too...

i never said water injection doesn't work... i just you have to be careful and suggested using ATF instead.

I'm saying... Well Check the bold...

Catalytic converters can either be an oxidation or three-way type. Oxidation catalysts convert carbon monoxide (CO) and hydrocarbons (HC) to carbon dioxide (CO2) and water, but have little effect on nitrogen oxides (NOx) and particulate matter. Three-way catalysts operate in a closed-loop system together with a lambda, or oxygen, sensor to regulate the air/fuel ratio on gasoline engines. The catalyst can then at the same time oxidize CO and HC to CO2 and water while reducing NOx to nitrogen.

has no relation to anything said in this post... the comment was water from the tailpipe and not steam...

but hey two thumbs up to the third grade reading level
