The bubbler is essentially a 'flame arrestor'. It separates the bulk of the gas from any flashback (from the intake) that could ignite the hydrogen in the canister.
In theory, anyway.... The water in the bubbler is the barrier- separates the systems. Different systems use different flame arrestors, but anytime you're dealing with hydrogen - you want a flame arrestor inline. Think Hindenburg. ***I bought one of these packet things online. I kinda wish I could get my $50 back. After reading some more and applying what I know about engine management systems, I have decided not to spend the time putting one of these in...The problem I see with the HHO thing is that you are going to raise your ignition temps to what should be dangerous levels for your exhaust valves. Hydrogen burns super hot, I believe. (and if you're using less gasoline, you're forfeiting the cooling effect of the petrol). It may work, but I feel fairly confident that the gains in fuel efficiency (lean burn) are going to be negated with the cost of engine repairs later on.
If anyone does this, I would install an exhaust temp sensor before doing the switch so that you can keep an eye on the change (if any) in ignition temps. I would defintely like to hear a positive experience from somebody credible on the forum.
I hate to be a naysayer, b/c I really want this to work.
