Last Call: Engines You Should Know Edition

Wooler The Wooler Flat Four is an amazing engine that eschews the traditional rods and crank for… well, rods and a crank. The difference is that each pair of cylinders is connected by a shared rod, and acts on a trunnion that actuates a secondary rod in an up and down motion that is then transferred into reciprocating motion on a separate crank. It was dreamed up by a man named John Wooler who put the clever motor in an equally clever shaft-drive motorcycle back in 1955. Sadly, Wooler died in 1956 and hence there are only five examples of his genius extant in the world. I thought you might like to know about them. Last Call indicates the end of Hooniverse’s broadcast day.  It’s meant to be an open forum for anyone and anything. Thread jacking is not only accepted, it’s encouraged. Image: Silodrome
