hydrogen on deisel

[Rhett]

Has any one got a hydrogen kit on there diesel? If so is it worth it? Im thinking of making on up or just getting a kit. I was thinking of putting it on a gu patrol td42t

your asking for a flaming

been debated to death when the fuel prices when sky high but its pretty dead in the water since then. its generally a gimmick that doesn't really work.
if your going to use water, why not water injection? even straight water will work and can get performance and economy with turbo diesels. but generally they use a bit of alcohol with it for more performance.

do you mean a real fuel cell? Or one of these fleabay kits? I love the statement that a car only uses less than half the amps produced by the alternator, and the rest is unused or wasted!

they can flame all they want, most of them are web wheelers anyway. I was just curios as Ive talked to two ppl in town in the last week and they both swear by it. they both built there owm kits. One sells tanks and has to deliver to frazer, he reckons he went from 3km a litre to 7ish towing a tank up the beach

I reckon he wasn't measuring his economy too accurately before, and he's still not measuring it too well now.

Most people put one of these kits on then start thinking about how inconsistently they drive. So they begin to drive less erratically, take better care of their vehicle (and think more about their tyre pressures, for instance) and suddenly find they're using less fuel.

Which would've happened without the "hydrogen generator" too.

In all the reading I've done I only found one report which I thought was credible - from a trucking fleet in North America (Canada?) which was saving sufficient fuel over millions of kilometres to justify the exorbitant price of the "professional" kits they were buying. A few percent - NOTHING like the figures your aquaintance is quoting.

But people will believe what they want to believe, and ignore anything which doesn't fit their beliefs. You're going to do this - you just want somebody to tell you it will work, and will ignore those who will tell you it's snake oil.

So just do it.

Diesel engines are pretty efficient for their cycle

Very little you can do will improve that efficiency other than driving style.

They already burn all the fuel unless not running right

so - nothign you add will "burn the fuel better"
therefore you are just burning the hydrogen
You only get back 10% of the total energy to produce it
So it costs diesel to produce it

Quid pro quo - it's less efficient.

Not hard to work out.

Rebuild your engine to run at a fixed RPM and load ratign, and only run it at that - then it will be more efficient.

Some reading for you

Here's a debate to start - "Do turbochargers improve efficiency"

The answer is no, the engine is less efficient. BUT, due to the weight / torque / driving behaviours, the vehicle may now be able to be made more efficient overall

i figure if its was so easy to save that much fuel car companies would be doing it standard.

My old man put one on his toyota rv ute 2006 model didnt do a thing cost around $2500 installed cant remember the company but the guy told us the government was looking at giving him a grant for more R&D anyway months and months went by nothing changed so he kept complaining and all they kept saying was turn up the amps (there was a little grub screw on the back of the unit that increases the amperage which basically creates a bigger chemical reaction) till eventually it could not be turned up any higher 2years have gone past and if anything it has made the fuel consumption worse and the company who built the unit have seemed to of vanished.

my old man drives 200k a day and 80% is 100k speed limit and gets about 14-16L per 100k before the unit was installed its now around 18L per 100k he will be removing it soon and we will see if there is any difference.

You sure about that one Paul?

thats like saying snorkels (with a ram head) dont improve economy or driveability on the highway
