This idea was used in Junkers Jumo 204, a 1930s aircraft engine. Supercharged diesel.

In WW2 a concept with the idea similar to Jumo 204 appeared, with four crankshafts instead of two in the 204, arranged in a skewed rectangle, appeared. It was called Jumo 223, with only one prototype built.

The British improved upon this idea and made a three-crank opposed piston engine, the Deltic. Originally intended to power fast torpedo boats, the most popular task the Deltic did was to power the Class 55 locomotive. Yup, it's also supercharged.

I find both engines extremely cool, especially the way they start.
