I decided to make a model engine. I have always had an interest in engineering and hands on projects so I thought it would be fun to make a model engine for my genius hour page. I didnt know very much on how engines work so I reseached the parts of car engines and how they all work together to complete the task. After reseaching about car engines, I looked up designs and models that I would try to make and I came across the can stirling engine. this is the design I made my model after. One thing I changed from my model is using a motor instead of a candle because the piston that I wouldve used broke so I switched to a motor because it is less likely to break. When the pistn broke that set me back a little bit but I was able to talk to my dad and see what he thought was a good idea and that helped out alot.
