Presently the 8-cylinder 90° V-type engine is often used in automobiles worldwide, but the bank angle of these engines is still restricted to only 90 degrees. When the permutations and combinations of the 8 cylinders are considered, it may be possible to find more moderate bank angles among them. We select 64 combinations of the 8-cylinder V-type engine, and find that they are grouped into 8-case according to the combination of the 8 cylinders. Each case has a different characteristic, and no system has vibration, unbalance or exciting moments, just like 90° V-type engines. Thus we found several new bank angles, such as the 8-cylinder 53°8' and 36°52' V-type engines, which have no vibration, exciting moment or eliminated moment.
