V8
A V8 engine is a V engine with eight cylinders. A V engine is a common configuration in larger engines in which the pistons are aligned so that if viewed from the front appear to be in a large V. The 8 refers to the fact that this configuration has 8 cylinders.The normal V-angle for a V8 is 90°. There are two classic types of V8s which differ by crankshaft.
The cross-plane V8 is the typical V8 configuration used in American road cars. Crank pins are at a 90° angle. The cross-plane can achieve very good balance but requires heavy counterweights on the crankshaft.
The flat-plane V8 have crank pins at 180°. They are imperfectly balanced and thus produces severe vibrations. As they don't requires counterweights, the crankshaft has less inertia allowing higher RPM. They're mainly used as racing engines the most famous example being the Ford-Cosworth DFV.
The Coventry-Climax 1,5 l V8 evolved from a cross-plane configuration to a flat-plane configuration in its latest versions.
