The engine block is a crucial component of an internal combustion engine. It serves as the foundation for various engine parts and provides structural support for the engine's operation.

Early engine blocks consisted of just cylinder blocks, to which separate crankcase was attached. Modern engine blocks typically have the crankcase integrated with the cylinder block as a single component.

Parts of Engine Block:
The main part of the engine block is a cylinder. It is the space in which a piston travels. Other parts are Coolant Passages, Oil Galleries, Crankcase, Bearings, Cylinder head, Cylinder liners, Deck Surface, and Camshaft housing.

How many types of engine blocks are there?
Three types of engine blocks are most common within modern cars: inline, V, and flat.

Inline engine blocks are most commonly found in smaller cars thanks to their simplicity. In this cylinder are arranged in a single line along the crankcase.

V engines have cylinders arranged in two banks at an angle to each other, forming a V shape when viewed from the front. Common angles for V engines are 60, 90, or 120 degrees.

Flat engine block
The third and final type of engine block is the flat engine block. In a flat engine, the cylinders are arranged horizontally and lie on opposite sides of the crankshaft, resembling a boxer's fists punching outward. This allows them to have a greater weight distribution and lower center of gravity.
