Correction to my comment about losing 10% of power, apparently this is
no longer the case with the latest conversion mod:
www.propane-generators.com/dedicated_kits.htm "This type of conversion
will produce FULL power because the carburetor is now delivering fuel at
the exact location that was engineered for the delivery of gasoline to
the engine air stream."

It happens that propane, as well as both alcohols, methanol and
ethanol, have an octane rating of 100. There is no reason not to
expect better efficiency and more power, compared to gasoline.The
carburetor designer's job is easier. You can realistically expect to
get the same near ideal mixture to all the cylinders. The perfect
fuel, actually.Historically, propane has been cheaper and there were
engines around that could use the octane..

Hmmm...the unspoken implication is that high octane implies high
energy content. It doesn't however. It's a common place that 90
octane can have higher energy content than 100 octane.
The high test stuff has better anti knock properties however, so
higher compression can provide better thermal efficiency using that
lower energy content fuel.

The "Tuk-Tuks", motorized tri-shaws, and most of the taxis in Bangkok
have been using LPG for years. In talking with the taxi drivers they
say that costs are about half what gasoline costs but they feel that
power is slightly less.

I did notice that the conversion shown in the URL is simply a modified
carburetor while the taxis here have a somewhat more sophisticated
system that includes a "boiler", a vaporizer heated by engine coolant,
to ensure complete vaporization of the LPG, but given normal
temperatures in Bangkok I have no idea why that should be required.
