The cylinder block and cylinder head are the two main structural components of an internal combustion engine. The cylinder block forms the engine's foundation and houses the cylinders, pistons, crankshaft, and cooling passages. The cylinder head sits on top of the block and contains the combustion chambers, valves, and valvetrain. Together, they form the combustion chamber and contain the pressure, heat, and forces generated by combustion.
