Im currerntly building my first engine. Its a horizontal unpresurised mini alpha engine. How should i ofsett the crankshaft? does the displacer piston go 90 degrees ahead of the power piston? Thanks

Re: alpha engine question
Well with alpha, both pistons and cylinders can be identical on same crank pin 90 apart.
Displacer is misnomer here. Either hot or cold piston.

Its a horizontal engine that looks like a gamma so no right angle to put on same pin. Im trying to copy this engine:

Re: alpha engine question
You can actually run a parallel GAMMA on a single crank pin by running the displacer via a bell crank, and an ALPHA could be run the same way. On this motor the bell crank ratio is 1.5 : 1, for an ALPHA motor the ratio would be 1 : 1
