Exploding engines (Road Trip pt. 1)

On the first leg of our road trip, we'll explore the history of engines and how they work, with a little help from Car Talk's Ray Magliozzi. The fundamentals of the internal combustion (or exploding) engine, haven't really changed since it was first invented in the 1800s. We'll find out how tiny explosions power our cars and hear how gas-powered cars came to dominate over electric and steam-powered engines.
