360° vs 180° vs 270° Crankshaft Angles in Parallel Twin Engine | Explained

360° vs 180° vs 270° Parallel Twin: Crankshaft Angles | Explained A straight-twin engine, also known as an inline-twin, vertical-twin, or parallel-twin, is a two-cylinder piston engine with cylinders arranged in a line along with a common crankshaft. Straight-twin engines are primarily used in motorcycles; other uses include marine vessels, snowmobiles, Jet Skis and all-terrain vehicles. The term "parallel-twin", "vertical-twin," and "inline-twin" originally had specific meanings relating to the crankshaft angle or engine orientation; however, they are often also used interchangeably. Various crankshaft configurations have been used for straight-twin engines, the most common being 360 degrees, 180 degrees, and 270 degrees. In the United Kingdom, the term "parallel-twin" is traditionally used for engines with a crankshaft angle of 360 degrees since the two pistons are in the same direction (i.e., parallel to each other). "Vertical-twin" was used to describe engines with a crankshaft angle of 180 degrees, which causes the pistons to travel in opposite directions. The terms "straight-twin" and "inline-twin" were used more generically for any crankshaft angle. So in this video, we are looking at different crankshaft configurations and how they are used in the automotive industry. ---- Time Stamp --- 00:00 - Introduction 01:19 - How does a 4-Stroke Engine work? 02:10 - Difference between Inline & Parallel Twin 03:02 - 360° Crankshaft Angle 04:52 - 180° Crankshaft Angle 07:35 - 270° Crankshaft Angle 10:59 - Wrap Up All images used in this video are under a creative commons license.
