A V-engine is an internal combustion engine in which the cylinders are arranged in two banks, which are at an angle to each other. The angle between the banks is typically 60 degrees, but it can be 45 degrees or 90 degrees.
V-engines are more compact than inline engines, which have the cylinders arranged in a single line. This makes them ideal for use in cars and trucks, where space is limited. V-engines are also more balanced than inline engines, which can make them smoother running.
