Monday's Science Lab: V-twin Engines 101
By Steven Verschoor, Jun. 27, 2005
And having brushed up on four-stroke engines, let's consider an engine layout which is near and dear to many of our hearts...
The V-twin engine comes in several variants, from a parallel, 0-degree layout to Harley's 45-degree layout to BMW's 180-degree structure.
You've probably heard that different layouts generate different shaking forces. Well here is an excellent schematic of the different forces generated by different engine layouts. Whether you choose to decifer the equations at the top or just study the dynamic illustrations, enjoy.
