Today we create a slide about the difference between an internal and an external combustion engine on the extra information slideshow. We looked at different examples of the internal and external engine. We also spent a bit of time looking at the Stirling engine. The piston and piston rings arrived and they fit inside the cylinder but the piston is slightly shorter than the old one so we are concerned the engine might not get enough compression. So at some point, this week or next week Luca's Dad will go to the repair shop and see if it matters. if it doesn't we will continue the reassembly.
