The first four priorities are :
Perform compression with a cold gas and keep it cold.
Make a temperature rise with a constant volume
Making an engine phase with hot gas and keeping it hot
Make cooling with a constant volume
Another priority is to have separate gas work volumes.
Another priority is that the heat transfer exchange times during the temperature rise operations or cooling are longer.
It was decided to remove the regenerator and use a heat exchanger instead for immediate recovery.of heat during the phases of temperature rise and heat
All the pistons are in phase and are driven by a rod-crank system.
All phases of the Stirling cycle take place simultaneously during each half turn.
Each phase of the cycle is 180 degrees (one half turn).
It takes two full turns to achieve a complete cycle.
The Stirling engine is in engine phase at all times.
The exchanger also works for 180 degrees.
1→2: compression phase (cold gas)
2→4 : temperature rise phase (via exchanger 3 to preheat the gas)
4→5: motor phase
5→1: cooling phase (via exchanger 3 for heat recovery)Patent-protected two-stroke Stirling engine : Ref. I.N.P.I. : FR1915384 - For more information, please contact the eXeco association: email@example.com
