As a side note, we revisited the idea of HHO in 2008 as I was part of an Xprize entry.

We modified a 2.4 L Mercedes diesel ( iron head ) by machining the glow plug holes to accept Ford long reach spark plugs and running the engine on syn-gas from diesel using a POx technique. HHO was added in a very small amount to smooth out the combustion. All the gasses were added in the intake and thus, the engine had to run very lean or destructive knock would occur at 21:1 compression ratio. The calculated AFR was well north of 30:1 . This is in corroboration with the findings of pfgPro on his turbo Talon. This engine was hoped to get our 190 D Mercedes near 100 mpg.
