(The Lycoming O-320 Engine Cutaway Project)
"(here)...are pictures of the Lycoming O-320 Engine Cutaway model we had the privilege of building for Western Michigan University's College Of Aviation to be used as a teaching aid for students to learn the internal workings of an aircraft engine. When finished you could turn the engine over and see everything move."

My alma matter

Good school, had lots of fun, drank lots of beer, met lots of good people, oh and got an education too boot.

Nice Work

Some very interesting pictures. I have already learned something from them. I didn't know that there were only 6 cam lobes. I assumed there were 8.

interesting catch- it looks like the middle cam shares two pushrods. I wonder if that one would show wear quicker than the outer pairs?

These are very good videos. I received them on DVD with my new engine. Highly recommended.

Bart at Aerosport pointed out to me that at least the 2 multi-purpose cam lobes open intake valves, so they don't have to work against combustion pressure.

Worn cam lobes are why an engine can have a good leak-down test and still be anemic on power.
