選定されているクランク軸構造。In an in-line multi-cylinder internal combustion engine, the shape and weight of the crankshaft counterweights are selected so that they are not all the same, and the counterweight closest to the flywheel has the largest weight, and its shape is similar to that between the crank pin and the crank journal. The crankshaft structure has been selected to have a shape that maximizes the section modulus across the entire length.
