It makes it appear that the limiting factor in getting better than 50% efficiency in a pure hydrogen motor is that it expands too damn fast, i.e. it exceeds the mechanical ability of reciprocating pistons to capture that power....

Ergo it would appear that H2 when moderated by a gasoline mixture i.e. as a small portion of it, would be capable of putting much more than 50% of it's energy to the crank...

Hmm..interesting. I wonder how it would behave with propane or ethanol? They burn cooler and cost less...

products are marketed as to help adjust your air/fuel ratio and get more efficiency from your HHO generator:

http://www.protiumfuelsystems.com/optimizer.html

The Optimizer (also known as a dual edge map sensor enhancer) gives you full control of the air/fuel mixture on any fuel injected engine* by attenuating the analog signal of either the MAF (Mass Air Flow) Sensor or the MAP (Manifold Absolute Pressure) Sensor. This allows you to increase your fuel economy while tailoring the settings to work with your driving habits and horsepower needs.

Most newer vehicles only need one adjustable parameter, however, the Optimizer is designed with two identical adjustment circuits giving you the ability to fine tune for low speeds under 40 MPH ('city') and a fine tuning for higher speeds ('Highway'). Plus, the control console can return your vehicle to it's normal operation or set for 'Performance' when extra horsepower is needed under a heavy load.

The purpose of this site is to bring to you gas savers that really work, thus saving you money, increasing the performance of your car, and making your car more environmentally friendly. Our current product line is limited to EFIE (Electronic Fuel Injection Enhancment) devices.

I am planning on installing my own HHO generator and have ordered the Protium engine optimizer. Don't know if it'll work but what the heck...won't know until I actually try it.

I noticed Protium has "Oxyisolators" which are just spacers ($5 from auto parts store). How is this better than an EFIE system?

from what I've read, it isn't better than an EFIE system but it allows the engine to run leaner since the O2 sensors detect less oxygen. I think EFIE systems are better but, it's costly compared to the the Oxyisolators.

Protium also stated that the oxyisolators will prevent your car from getting the check engine light when the air/fuel ratio is leaned out. Don't know for sure if it's true since I haven't tried them yet (but I have ordered them). we'll see.
