X engine

Not to be confused with LiquidPiston’s X-engine.
X-engine according to US Patent 1889583 (Eingetragen 1928)[1]
Symmetrical X-Engine (90°/90°/90°/90°)

An X engine is a piston engine with four banks of cylinders around a common crankshaft, such that the cylinders form an "X" shape when viewed front-on.

The advantage of an X engine is that it is shorter than a V engine of the same number of cylinders,[2] however the drawbacks are greater weight and complexity as compared to a radial engine. Therefore, the configuration has been rarely used.

Several of the X engine designs were based on combining two V engines.
