Every major automobile manufacturer offers a line of industrial
engines. There is also an extensive network of professional
over-haul shops that specialize in industrial engines.

For 2008 GM is introducing lighter weight Brazilian built utility
engines to replace the all-cast-iron models that have been standard
since the late 1940's.

The world can't run without utility engines for deep-well pumps, air
compressors, portable arc welders, orchard sprayers, fork lifts, all
manner of farm equipment... Many of these engines are an EXACT
match for the Model A but being of modern design, they offer better
durability and reduced fuel consumption, typically at less weight.


INteresting. The only one I know of commonly used for aviation is
that little 2 cyl Onan they put on Quickies. I know some ultralight
guys use the
little Continental 084s as well.

Not sure whether the little Onan boxer is still in production. Most
of the little opposed cylinder flat heads have been replaced with
overhead valve Vee-twins. I strongly suspect that the switch to Vee
configuration was to fit the new engines within the width of the
equipment that the older flat head engines typically powered--but I
really don't know with any certainty.

Yeah, I saw one of those being peddled as an ultrlight engine a few
years ago. V twons haven;t done well as airplane engines. I can't recall
seeing many installed.

I looked for a little info on the Continental O-84 and could only find
that it is a 4 cylinder of 21 cubic inches per cylinder. From that, I
would expect a power rating of 40 to 50 HP and a weight of 90 to 105
pounds, which would be appropriate for a single seat LSA with a gross
weight of 600 to 650 pounds. But, I don't know the actual specs and
am curious to learn more.


I saw a website about converting them some time ago. There's a slightly
smaller twin as well.I know that at least a fw airplanes have been
successfully flown behind the 084. there is a guy who sells them new,
surplus for only about $800. There's a bit of work to be done to make
them usable as an airplane engine, but nothing crazy. Just a prop
flange, cut off the ole shroud and mess aroudn with the inlet manifold
so the carb isn't in yor windscreen.
