Ask Lemmy

Preface: I know NOTHING about combustion engines and generally have never had the desire to.

But the “Driving 4 Answers” channel breaks down how all kinds of different engine designs work, explaining the pros and cons of each. Some have tons of apparent advantages that make you wonder why they aren’t used in production cars and trucks. He digs deep to answer that question.

Here’s a great video about the rotary vane engine.

The twin rod Avadi engine is a very different approach.

This one explains the crossplane inline 4. I had never even heard of such a thing before, but the way it’s explained is absolutely fascinating. He even demonstrates the different sounds so I feel like I could just listen to a car and know what kind of crankshaft it has.

Highly recommended.
