Gamma Type Troubleshooting
Posted: Fri Nov 22, 2013 7:24 am
I have made a gamma type Stirling engine with the following specs:
Power cylinder volume = 70 cc
Displacer cylinder volume = 100 cc
Compression ratio of displacer = 2
Crank angle = 90 degrees
Cylinder pressure = 101 kPa
Displacer piston stroke = 41.4 mm
Displacer piston length = 47 mm
The power piston and cylinder I used was of Honda 70cc motorbike.
The engine did not run when tested under a bunsen burner's flame. I have ruled out the following tweaks to the engine: Increasing the initial cylinder pressure and reducing frictional effects from the power piston. I am attaching the image of my design.
My piston seals the power cylinder with a teflon piston ring but it creates a lot of frictional effects. Can you suggest a better option? And any other suggestions as to why the engine did not run will be greatly appreciated.
