Weirdest Engines Ever Made Explained

The weirdest engines ever built — from a British diesel with three crankshafts arranged in a triangle, to a French car engine so extravagant that it spent 20 years pulling passenger trains across France. This video breaks down 9 of the strangest engines in engineering history, ranked from mechanical oddities to concepts so ambitious they outlived the vehicles they were built for. Some of these engines still run today. Others were so complicated they took days to service. And one of them has the entire engine block spinning around a fixed crankshaft while the car is being driven. Every entry is a real engine — some famous, some almost forgotten.
