The main structural housing for engine cylinders, pistons, and crankshaft in internal combustion engines.
A cylinder block is the foundational engine component that forms the main structural frame of an internal combustion engine. It houses the cylinders where combustion occurs, contains coolant and oil passages for thermal management and lubrication, provides mounting points for the crankshaft and cylinder head, and integrates with other engine systems. Modern designs often incorporate integrated components like camshaft bearings and accessory mounts to reduce assembly complexity and improve structural integrity.

These terms are often used interchangeably, but technically the cylinder block refers specifically to the structure containing cylinders, while engine block may include integrated components like the crankcase. Modern designs typically combine both into a single casting.
Quality testing includes pressure testing of coolant and oil passages (typically 200-300 kPa above operating pressure), dimensional verification using coordinate measuring machines, material composition analysis through spectroscopy, and non-destructive testing like ultrasonic inspection for casting defects.
Common failure modes include thermal cracking from overheating, corrosion in coolant passages, bore wear from piston ring friction, main bearing cap walk from excessive loads, and porosity leaks from casting defects.
