Thread: WHAT ENGINE IS THAT?

USAF Museum, Dayton & Museum of American Speed, Lincoln.

The aero engine is a Junkers Jumo 211D, can't work out the other.

Next two.

One is an aero engine and one is a race car engine. I know what they are.

g'day Brian Hjelm

The first engine looks like a Packard Merlin of WW11 vintage built under license from Rolls Royce to power Spitfire & Hurricanes but was also used in Lancasters, second motor looks like Ferrari

Sorry, Uncle. No cigar for you.

No more guesses on those?

OK, one is a Ranger V770 inverted V12 aircraft engine. The other is a Volker V12 from 1937. The Volkers raced at Indianapolis from 1937 to 1947 and never did much good. One was updated in 1977 and a car was being built for it but never got finished. The patternmaker spelt Volker as Voelker which I was told really got up Charlie Volker's nose.

Here are a couple more. One aero and one automotive.

The aero engine is a Liberty L4. A four cylinder engine based on the Liberty V12. It was intended for trainer aircraft but other engines were readily available and the L4 never went into production.

The other is a Meyer and Drake "Offenhauser 111" centrifugally supercharged and intercooled. The supercharger is driven by a gear on the end of the crankshaft at several times engine speed. The plate intercooler is a piece of metalworkers art.
