Re: GAS-L: Internal Combustion with Producer Gas

[Peter Singfield <snkm@btl.net>]

Hi Tom T;

I see no reason it will not work for a two stroke diesel except efficiency
will be lost due to exhaust losses.

However -- in applications where heat is needed -- such as drying rice --
this should not be a problem. Further mixing with the right amount air (say
even hot air from the radiator) should also allow that residual gas to burn.

There probably is already enough air just in that scavenging!

The experiment would be simply hooking up to the 2 stroke as is presently
achieved with the four stroke. Except the gasifier will have to be much
larger than for the same HP 4 stroke.

Most electrical power diesel gen sets here -- those around the 100 kwh size
-- are GMC two strokes. They "gang" these together to produce the total
amount required.

Even the saw mills use a lot of GMC's. Though Caterpillar bull dozer
engines are used as well.

Interesting what happens when we try to apply this technology to real
circumstances in 3rd world. Totally different scenario than a modern
industrial country with all those Government grants.

Personally -- I feel gasification must be geared to 3rd world -- where the
demand for such exists now -- rather than more exotic "experiments" in 1st
world.
