No more black smoke!!

I have been experimenting with a HHO fuel system on the 2.4 and I have got a 75% reduction in exhaust emissions. So those ridiculous clouds of black smoke are now a thing of the past

Nice one Mark-still drives as before?

What is a HHO fuel system and how do you experiment with it?

Its a small box mounted in the boot filled with water and connected to the battery. It produces a combination of hydrogen and oxygen gas called HHO gas and its piped to the intake to mix with the diesel. It increases mpg aswell, I'll be testing that tomorrow. Drives the same with a possible slight increase in power but hard to tell yet.

We couldn't really believe it either. It was so bad to begin with it, it was maxing out the reading on the smoke meter! Averaged an opacity of 8.84, NCT pass rate is 3.0! But with the HHO gas it was reduced to 2.2!

Sounds good, I never got around to playing with anything like that..

One question, is the gas injected before the MAF or after the MAF? I'm assuming post-MAF, right before the throttlebody?

Its after the MAF and before the turbo. Putting it after the turbo is supposed to cause problems because of the pressure? I might try it once I've done some mpg tests.

I assume you are relying on the suck of the turbo to pull the gas through, rather than there being a pump? If there was no pump, and the gas pipe was installed after the turbo the positive pressure in the pipes would stop any gas flowing through..

You're spot on There is no pump and its just sucked through. Simple but effective!

How do you regulate how much gas is created? I guess you have to keep topping up the water.. How much does it get through over a certain amount of miles?

There are different size units for certain engine sizes so it creates a set amount of gas and its used as its made. It holds about 2.5 litres and should go 200-300 miles before needing topping up but I havn't gone that far yet.

Say 2.5 litres of water per 250 miles - thats 1 litre per hundred miles. 1l of water is 20% hydrogen by weight, so 1litre of water -> 200g of hydrogen + 800g of oxygen. 200g over 100 miles is only 2g of gas per mile, compared to 100-150g of diesel used over a similar distance.. I'm suprised its made so much noticeable difference. Is the pipe that goes to the container of liquid completely air-tight? As if the turbo was drawing in air through that pipe along with the gasmix, it would result in less air being drawn through the MAF, and less air registered = less fuel injected, and less fuel = less black smoke.. But you say power feels better? Gotta be doing something then.. When will it be going on the rolling road again? And by the way, what did it make last time it was on the RR?

It won't use all the 2.5 litres in 200-300 miles but maybe just need topping up. I have over 100 miles done now and its hardly used any water. Im still putting it through its paces before I buy in a large order. There are 1,366 litres of hydrogen in a litre of water!
It made 177.8 hp and 343 ft.lb. with a very badly blowing flexi pipe!
