IFALPA's Hall of Fame

Louis Zeyfurt's engine... Louis' handwriting is a little difficult to read so the text is transcribed below.

Top of diagram:  

"The basic pump-action function of each cylinder - note the (Omega) Zeyfurt configuration".

Right side instructions:
"The O = Zeyfert basic cycle of one cylinder.
Notes that the suck-in phase should sound loud and similar to the one you would make if you stubbed your toe. 
The boom-phase note is simple "mmmm" in compression turning to "WAH".
Blow-out is the "Polish Rhubard, Bronx Cheer or Raspberry" - loud and sustained.

Thus the audio-tones would be "SSSSSS" - "MMMMM A" - and "THRRRRURP"

Ancillary equipments, Carburettor, Magnetoes and Propeller are not shown.

Notes below: 

"At one time a Vee-8 was considered, but considered dangerous, and a prone, floor-mounted radial with Louis as the Master Cylinder was rejected due to dirt on suits from the floor.
So the ZEYFERT ALCOHOL-FUELLED, NORMALLY ASPIRATED ROPE-DRIVEN POPPET-VALVED OTTO-CYCLED PRIME MOVER STRAIGHT FOUR, REMAINS THE GENUINE a-o SET AFTER-DINNER PIECE.  CAPT. HANK VERMUELLEN (WHOM GOD PRESERVE, OF BUSSUM) IS THE CHIEF INSTRUCTOR, COACH AND SELECTION COMMITTEE ON A LIFETIME APPOINTMENT IN THE CYBERNETICS DIVISION OF THE CLUB, THIS DIVISION IS PERMANENTLY BASED IN THE NETHERLANDS.

This schematic is designed so as to assist you in your practice. It is advisable to practice in private as lesser mortals are apt to make judgements about us all. Even children have been known to wonder if they have inherited some weird hidden habits from Daddy."
