Common angle of cylinder

2021-03-01

In automotive internal combustion engines, we mentioned that the "cylinder included angle" is often a V-type engine. Among V-type engines, the common angle is 60 degrees and 90 degrees. The cylinder included angle of horizontally opposed engines is 180 degrees. 

The 60-degree included angle is the most optimized design, which is the result of numerous scientific experiments. Therefore, most of the V6 engines adopt this layout.
The more special one is Volkswagen’s VR6 engine, which uses a 15-degree included angle design, which makes the engine very compact and can even meet the requirements of horizontal engine design. Subsequently, Volkswagen’s W-type engine is equivalent to two VR6 engines. The V-shaped product has an angle of 15 degrees between the two rows of cylinders on one side, and an angle of 72 degrees between the left and right sets of cylinders.
