Hi,
After a few Stirling engine, I would like to build an IC engine (either the "tiny" or the "webster"). As I live in Europe, I'm currently converting both plans to metric.
To get some more insights, I calculated the compression ratio of both the "Tiny" and the "Webster" and they are ~2.5 times, which seems to be very low (compared to those of Jan Ridders' engines which are ~ 4.5).
Mayby I'm making a mistake here, so did anyone ever calculated the compression ratio of the "Tiny" or "Webster" before?
Thanks in advance,
Xander
