Steam Engine Specifications/Geometry
Main > Energy > Steam Engine
For analysis and dimension purposes, the following are defined:
| Variable | Exlanation |
|---|---|
| Clen | Interior length of the cylinder. |
| Cdia | Interior diameter of the cylinder (or perhaps the sleeve). |
| Coff | Distance from the end of cylinder to the center of the crankshaft. |
| Ptrav | Total distance the piston travels. |
| Pstrt | Piston starting point (bump valve fully open). |
| Pmid | Piston mid-point. Max crankshaft offset. |
| Pend | Piston end point. |
| Prod | Piston rod length. |
| Soff | Crankshaft offset. |
Questions to be answered given the geometry:
- How long does the piston rod (Prod) have to be?
- Given a Cdia, how long is Coff to clear the end of the cylinder?
