I thought I'd let you guys know what I'm trying out.
A hydrogen fuel cell on my Avensis D4D 2004 T-Spirit 2.0 Turbo diesel. 126,000 on the clock with full service history.
At the moment I'm getting 38 - 41 mpg. ( I find 60 mph a little boring ! Ha Ha ) Tyres are Goodyear Efficiencey 215 x 50 x 17. ( should have 45's on as standard but due to my job I like the 50's on, easier on speed bumps )

Right,
Thats all the bumpff out the way.

I bought this system from America, It's pretty neat & tidy. And best of all, it's small ! Compared to the other units I've read about & seen.
I'm going to ad links & stuff but I'm not to hot with a laptop ! Ha Ha

Just incase you think I'm promoting them, I'M NOT !
I'm just a customer. Watch your ***** for the parcelforce charge & customs charges. I got bumped out of £52.00 ! NOT IMPRESSED LIKE !
Anyway ! I've got it now !

Have a look though coz it looks a good system with a 5 year Gaurentee ? Mmmmmmm ! You never know though !

Mines is half fitted just now ! I waiting on a mate to wire up the relays & stuff although I'm going to have a blast at it myself as the wiring is so simple.
Honestly, if I'm thinking of doing it, it needs to be pretty easy.....

I'll upload a couple of recent diesel reciepts so you can work out my mpg incase I've not done my sums correct. Ha Ha

I'd be interested to know if any of you guys have tried it or have any ( sensible suggestions ) ?

Don't bother if your just going to take the *****, I'm trying it out either way !

I'll put an update with pictures of wiring, just incase anybody else wants to know how I done it.

The only extras you will need if your'e trying it my way will be a piece of sturdy galv sheet or similar. About 18" x 6" to make a little bracket (Front Grill). And a little support bracket for the big white bottle (front grill). You'll also need 5 or 6 self tappers. ( I did )
I also bought a combi amp/voltmeter off ebay for £15.00

If you want to know anything, just give me a shout. I'll pop on every couple of days.

Good luck.. it will be realy interesting to get feedback. Strange, this hho system is known for decade, but.. i haven't seen anyone using it, even taxis. Why? Maybe because you will get water in your exhaust, and it will corode faster. Maybe if you get your water into oil, you will change your engine. Or maybe system is just not efective, becaise generating h you need lots of electricity. I am realy waiting for your experience. Good luck

Hello mate,
yes I for one will be very interested to hear how you get on. There is a company local to me who fits a similar system and charge £300.00 per unit fitted, one unit per 1000cc of engine capacity so 2 units for a 2 ltr diesel. The theory sounds good and I have done lot of reading up on the subject, tempted but not convinced due th the heavy load it puts on the alternator which uses extra fuel and as the other reply says taxi drivers and white van men would all have it but .... like I say I am genuinely interested and hopeful for a positive outcome for you.

Regards ... Pete. :thumbsup:

one more thing forgot to mention - using hho system you need to change o2 sensor values. Additional h2o in exaust will make ECU to correct fuel mixture - it will think your engine is running on a leaner mixture. It means, ECU supplies more fuel to burn, and you will have something else but not savings anymore.. Well, if installations are correct ( i think o2 sensor emulation should be done), maybe everything should be fine. but in this case you have to look at your mpg everytime for possible problems while ECU won't see real o2 measurements.
