vw engine air compressor
 

I had a link for this years ago, but cant find it. Anyone got it handy ?

it was a bug engine that ran on 2 barrels one side, and the other side
was used as a high output air compressor.

TIA

Used to be called "Volks-Air".
Now "Dunn Right"

Actually, it was probably configured with two OPPOSED cylinders to
provide power, the other pair to act as the air pump.

As a point of interest, people have been doing his type of conversion
since before the First World War. In 2000 I posted a message to this
Newsgroup explaining how to convert a running VW engine into a two-
cylinder air compressor without having to dismantle the engine.
(Search this Newsgroup using 'veeduber air-compressor' as your seed.)
But it assumes you already know the basics of air compressors. What
Dunn-Right offers is a complete kit of all the bits & pieces.

Plus, as I understand it, a special cam that makes it work more
efficiently.

The method I described disables the valves for the cylinders that are
used to pump air, allowing them to pump on each stroke.

Convincing a couple of jugs of any OHV engine to pump air is a fairly
trivial chore for those who know their onions. For everyone else, the
Dunn-Right kit is a very practical option.

My grand father had an adaptor for the Model T that would provide compressed
air by removing one of the spark plugs. Only draw back the air had a lot of
gas fumes.

I still have that tool sold by JCWhitney that allowed you to do that.
Gee now I do feel old! lol

Now you scare me if I ever use that air to pump up a tire! 8^o
I think it was redesigned and the compression from the engine allowed this
pump to draw fresh air and then pressurize it.
At least that is what I believe! <g>

The typical 'spark plug' compressor was a captive, spring-loaded
piston in a brass cylinder that screwed in to the spark plug hole. The
engine's compression stroke powered the device to pump ambient air,
not the charge from the cylinder. The instructions said to give it a
drop of oil before screwing it into place but little if any of that
oil found its way into the output.

I've heard several people say the things used air from the engine so
there may have been some that simply diverted the fuel/air charge into
a tire, but none of the ones I've ever seen or used worked like that.
And they DO work rather well. Displacement was typically one cubic
inch so the output was about .25cfm at an idle (ie, about 400 strokes
per minute). Pressure depended on the compression ratio & condition
of the engine -- you wouldn't get much from a Model T but then its
tires didn't need very much. On a 1953 Mercury flat-head V8 you'd see
better than 120psi and most VW's could do 75 to 90 psi.
