So Bob, lets think about this, my cylinder head has screw plugs for compatibility with a smog pump. I can tap right into each exhaust port prior to hitting the header.

I was thinking about port one of the center smog outlets into a bubbler, and in turn, have a pipe that goes from the bubbler right into the air intake, to introduce water vapor, and heated exhaust. Think it might work?

On another note, what if we used the same system, but had a 2 bubblers with a gas vaporizer in between.

Hot exhaust would enter the first bubbler, exit into the gas vaporizer, and into the 2nd bubbler, and then finally back into the intake manifold.

sorry, just had lots of thoughts today. :D

From wikipedia.org:

Criticisms of catalytic converters

Catalytic converters have proven to be reliable devices and have been successful in reducing noxious tailpipe emissions. However, they have two adverse environmental impacts in use (ignoring the pollution caused in their manufacture, which would not exist were they not mandated):

* The requirement for the engine to run at the stoichiometric point means fuel economy is not as good as that of a "lean burn" engine running at a mixture of 20:1 or weaker. This increases the rate at which fossil fuel resources are consumed and the carbon dioxide emissions of the vehicle.
* Catalytic converters are estimated to account for 50% of total nitrous oxide (dinitrogen oxide, 'laughing gas') emissions to atmosphere. While N2O emissions in these concentrations are not harmful to human health, it is a potent greenhouse gas, accounting for around 7% of the overall greenhouse effect despite its small concentration in the atmosphere.

Therefore one conclusion is that catalysts have reduced toxic emissions and the incidence of smog at the expense of increased global warming.


SO, it appears that the 14.7:1 ratio is a mandate because of catalytic converters, and not because that is the best ratio for an ICE, which makes sense due to the O2 requirement of the cat converter in order to oxize carbon monoxide.

Think about how the implications of that combined with electronic fuel injection completely fixates the ratio in which we combust fuel. What an uphill battle. Thank goodness for laptops and OSD adapters...
