Mechanical Engineering · Last updated: July 30, 2026 · How this entry was written
Definition: The engine block is the main structural component of an internal combustion engine that houses the cylinders, crankshaft, and often the camshaft. It provides mounting points for other engine parts and contains coolant and oil passages.
Example in context
“When rebuilding an engine, the engine block must be inspected for cracks, cylinder bore wear, and deck flatness before assembly.”
“Motor yeniden yapılırken, montajdan önce motor bloğu çatlaklar, silindir aşınması ve üst yüzey düzlüğü açısından incelenmelidir.”
Where engineers use it
The engine block is the foundation of the engine; engineers specify materials like cast iron or aluminum alloys for strength and weight. It is machined for cylinder bores, oil galleries, and coolant jackets during manufacturing.
Synonyms: cylinder block, block
