Mystery engine - Henry Harris - 01-04-2021
This Austin Motor Company image is from 'Austin Racing History' by Harrison, 1949.
It is wrongly captioned as ' "Ulster" power unit showing the Cozette supercharger'.
It's an off-set single seater engine but with a crank starting handle.
Interesting details include Zoller supercharger, C35 dynamo but no starter motor, coil ignition and 3 speed type gearbox with 'crash' type lid (possibly with 4 forward gears , no reverse)
I guess it's 1932 but what was it fitted to?
RE: Mystery engine - Hedd_Jones - 01-04-2021
Is it not the German Rubber Duck engine, you posted pictures of the crankcase of the sand racer elsewhere this week? Which would be the same?
RE: Mystery engine - Chris.Dallas - 01-04-2021
Definitely looks like a ‘Duck’ crankcase, possibly an earlier experimental set up when fitted to an ulster for testing, hence the handle?

Henry,
It doesn't look like a C35 dynamo to me more akin to a bigger Austin.
RE: Mystery engine - Ruairidh Dunford - 01-04-2021
It is very similar to the one fitted to our 12/4.

Hi All
The pic bears non of Tony’s photoshop skills so I guess it can’t be an April fool posting?
Cheers
Howard

Robert and Ruairidh,
I think you're right about the dynamo. It appears to be a larger diameter than a C35.
Which would make it the next size up. C45 with a 25 amp output. But why, and without a starter motor?
RE: Mystery engine - Mike Costigan - 02-04-2021
Large dynamo and no starter, but coil ignition - built for long-distance records, perhaps?
RE: Mystery engine - Stuart Joseph - 02-04-2021
How does the clutch operate - no obvious pedal or have I missed something ?
RE: Mystery engine - Rick F - 02-04-2021
Good question, Stuart. The shaft is there, with what might be a spring, but that strange casting would appear to prevent any lever movement. Unless the clutch lever is at the opposite side, of course - left-hand drive?
