What is Engine Block?

1 minuteread

Engine Block:

An engine block is a structure that contains the cylinders, and other parts, of an inside combustion engine. In an early automotive engine, the cast consisted of just the block, to which a separate crankcase was attached. Modern engine blocks typically have the crankcase integrated with the cylinder block as a single component. Engine blocks often also include elements like coolant passages and oil galleries.

The term “cylinder block” is usually used interchangeably with the cylinder block, although technically the block of a contemporary engine (i.e. multiple cylinders in a very single component) would be classified as a monobloc.

Usually made of an aluminum alloy on modern cars, on older vehicles and trucks it had been commonly forged iron. Its metal construction gives it strength and also the ability to transmit heat from the combustion processes to the integral cooling system in an efficient manner. Aluminum block typically has an iron sleeve pressed into them for the piston bores, or a special hard plating applied to the bores after machining.

The block was originally just a block of metal holding the cylinder bores, the water cooling jacket, oil passages, and therefore the crankcase. This vessel, as it’s sometimes known, is an empty system of passages, circulating coolant within the cylinder block. The vessel surrounds the engine’s cylinders, of which there are usually four, six, or eight and which contain the pistons.
