If it can produce sufficient hydrogen in the time available it just might work but I doubt it can and I also suspect that for to do so would use up any savings in driving the alternator because of the extra electrical load. Remember LPG in diesels is essentially just introduced into the combustion chamber via the inlet so the governor reduces the fuel delivered as the LPG makes the engine speed up.
The talk about speeding up combustion raises concerns about petrol engines. We used to use lead to slow down the combustion because if it goes too fast it compresses unburned mixture in front of the flame front so it explodes - that’s called pinking or detonation. Modern petrol engines "listen" for detonation and when it hears it the ignition is retarded until the detonation stops. Retarded ignition increases fuel consumption and reduces performance so I agree snake oil but with a slight basis in physics.

You are right Tony I used to convert a few diesels to add LPG it was hard work getting it right. However when they were right they were quick and very very clean. I am surprised that more lorry companies dont use it as the reduction in running cost and the clean up on the exhaust is amazing

One saves 30% fuel. If you buy two, that will save 60% fuel consumption. I'm buying three to save 90%. And will be laughing all the way to the bank!

I understand the principle of splitting water and running an engine off the hydrogen. This has been done for years, a guy in America was the first for becoming known for it. But I don't think this unit could produce enough to make a difference.

And will be laughing all the way to the bank! you've missed the point. if you buy five you save 150%, so you can feed hydrogen back into the lpg pump, reversing the fuel pump's meter and claiming a cashback at the pay station. what's not to like? |

Sabre Narrowboats had one fitted on the boat they exhibited at the IWA festival in 2008 or 9. It was reviewed in Waterways World at the time but dont recall what they said about it. The boat was called Sandoy and is moored on the Bridgewater. Spoke to the owner a few years ago who said it was removed once the show finished.

Now that might work for a CCer who only runs their engine every 14 days and has enough space for the electrolyser run by solar and hydrogen storage but it would have to be a large storage tank I would have thought. Better to spend the money and effort installing LPG but where you fill up is another thing. We know LPG - diesel engines work. |

A completely different gas to hydrogen. But as the gimp has no understanding of the issues he gets confused. |

Are you sure? Most combustible gasses have a proportion of hydrogen in them and injecting steam into the retorts at town gas works served to increase it. They do something similar in at least one diesel powered fuel cell when they mix CO from burning the fuel rich with steam from the cell pile to make hydrogen.
I think its the proportion of carbon to hydrogen that more or less defines the type of combustible gas.
