Those results have been discussed elsewhere on this board in this context. Two very important points about them:

1 - It's diesel, most "HHO" discussions are about gasoline-powered cars.
2 - The quantities of hydrogen used in that experiment are a couple of orders of magnitude higher than come out of these on-board hydrogen generators.

So if you can get a whole lot of hydrogen for free, compress it for just about free, and store it on board your diesel car, you can get better economy until your bottle runs out. But that is a very far cry indeed from using the car's engine to generate hydrogen and then burning that in with the gasoline powering your spark-ignition engine.
