Like a boxing competitor punching his gloves, A flat-4 or horizontally-opposed-4 is a flat engine with four pistons/cylinders arranged by two on each side horizontally mounted on the crankshaft such that opposing pistons move back and forth in opposite directions at the same time, is being referred to as a boxer engine. The configuration results a good balance of parts, a low centre of gravity, and a very short engine length. The layout also lends itself to efficient air cooling.
I heard that having horizontal cylinders cause to wear cylinder rings unevenly ???
