What term applies to an engine comprising two banks of four cylinders inclined towards each other, with a common crankshaft?
V8 engine V8 engine A V8 engine is an eight-cylinder V configuration engine with the cylinders mounted on the crankcase in two sets (or banks) of four, with all eight pistons driving a common crankshaft. Most banks are set at a right angle (90°) to each other, some at a narrower angle, with 45°, 60°, and 72° most common. In its simplest form, the V8 is basically two parallel inline-four engines sharing a common crankshaft. However, this simple configuration, with a flat- or single-plane crankshaft, has the same secondary dynamic imbalance problems as two straight-4s, resulting in vibrations in large engine displacements.
Inline-four engine Inline-four engine The inline-four engine or straight-four engine is a type of inline internal combustion four-cylinder engine with all four cylinders mounted in a straight line, or plane along the crankcase. The single bank of cylinders may be oriented in either a vertical or an inclined plane with all the pistons driving a common crankshaft. Where it is inclined, it is sometimes called a slant-four. In a specification chart or when an abbreviation is used, an inline-four engine is listed either as I4 or L4 (for "longitudinal", to avoid confusion between the digit 1 and the letter I).
