Water injection anyone

Read on the net that water injection is good for the car.

 

Wondering if anyone here has tried that?

 

Any comments?

 

Thanks

Can DIY or not?

 

 

Let say theoritically, I put a wet sponge near the throttle opening and manage to some how keep it wet. Will it benefit my car?

 

I heard about adjusting the amount of water. Let's say best mix is 10% at start up and 30% at 100km/h. If I just keep at 10% all the while, can I say there be benefits rather than not having it at all?

 

Comments please?

Read, learned, seen through 3rd party only, have not touch yet about silicon injection but water injection?

 

What does it do to the car?

Water injection is based on some thoery that by lowering the temperature of the combustion chamber with water, the car can achieve better and more complete combustion leading to fuel-saving and power.

 

Errr... what is silicon injection.. for car or human? [crazy]

There's no benefit in wetting the throttle opening (??) as it's not heat dependent.

 

Extracted from a turbo website on the purpose of water injection:

 

To add to the life of the turbo unit, some turbos are also water-cooled by coolant system connections. This feature limits the operating temperature of the turbo to the temperature of the cooling system, thus, protecting the bearing assemble from excessive exhaust temperature. [;)]

I think we may be talking about different water injection.

 

I am refering to introducing water droplets into the combustion chamber. The thoery is to cool the combustion temperature down for more complete combustion for better fuel burning and power.

 

 

Thanks [thumbsup]

The turbo article you quoted is to protect the turbo from the exhaust heat.

 

 

Now applicable leh [dizzy]

Water injection is to prevent detonation by inhibiting the combustion cycle a split second slower. By injecting water mist (very fine one I must add) the amount of oxygen in the intake is also reduced but for that price the boost can be raised even higher without risk of detonation.

 

Water injection is almost redundant for NA cars unless you have NOS or running on nitro-methane, now for a turbo/supercharged car running high boost it's a life (or engine) saver. Considering that, I ran with 1.2bar of boost with spikes at 1.4bar without water injection and my brick ran fine (with plenty of TLC of course [thumbsup] ). Depending on the engine and amount of boost generated, water injection is usually one of the last steps in turbo tuning, larger intercooler is more cost effective.

 

Whew! [sweatdrop]

 

P.S. I have a book on turbocharging and water injection is a lengthy chapter! [dizzy]

Pardon me.

 

What is NA cars?

 

In nutshell, your advice to forget water injection right?

our Cars are NA.. no turbo, just fuel injection. Natural Aspirated Cars. (My spelling might be wrong hor)

 

FOr your accent.. depending what you are. (I forgot is it manual or auto).

 

Yes.. don't waste time on Water INjection. A proper cooling such as bigger radiator or ATF cooler will give you more horses.. Auto Transmission Cooler. In normal cars, the ATF cooling is shared by the radiator. Seperating it gives you more cooling to your engine and ATF. Alternative go for the fuel rail..

 

I know of one accent actually had a bigger radiator installed. If you want to change it, remember, it void warranty.

Mine's an auto.

 

Can I say safely that lowering the temperature of my engine compartment is good for my car?

 

Let say if I rip my bonnet off and drive, is that better than with the bonnet?

 

Thanks

Every engine needs a certain temperature to start moving. Lowerig it makes it able to push more out of it especially in hard driving.

 

We are talking about cooling and not getting more air. 2 different matters.

 

Water is better cooling element then air

 

Coolent is the based element. When you use coolent to cool engine and trans, it is more efficient then air.
