V4 engine animation

An animation of a V4 engine, using a 90 degree flying pin design. Like a boxer 4, piston pairs are located on the same crank position, except at a 90 degree spread. If the rear piston was trailing the front piston by 90 degrees then piston pairs would lay on different crank pins.
