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 Rich |

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.

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. -R.S.Hoover |

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> -- later, dave (One out of many daves) "NotMe" > wrote > > My grand father had an adaptor for the Model T that would provide > compressed > air by removing one of the spark plugs.

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. -Bob Hoover |
