Description
The cylinder block is one of the most important designs in the
engine. Just as head, the cylinder block is also designed to
achieve certain performance parameters. It must sustain very high
pressures and temperatures running above 600 degrees Celsius. They
employ precision machining to give mirror finish to cylinder
surfaces. This includes accurate grinding and honing processes.
The cylinder block casting incorporates many unique cast-in
internal features which reduce machining costs, including: high
pressure oil passages, oil drain-backs, the crankcase air passages,
and coolant jackets and channels. On the exterior of the block
there are numerous ribs, pads, channels, and holes for
strengthening, weight reduction, and accessory attachment.
Engine block components
1. Cylinder blocks. A cylinder block is the structure which
contains the cylinder, plus any cylinder sleeves and coolant
passages.
2. Oil passages
3. Crankcase. An engine where all the cylinders share a common
block is called a monobloc engine.
What are the main features of cylinder block?
1. Cylinder head covers: the cylinder head is mounted on top of the
engine block with long bolts.
2. Cylinder head
3. Engine block: an engine block can be a single or split in two,
upper and lower block. It encloses the piston, connecting rod, etc.
as they work in it.

What are the materials used for cylinder blocks?
Actually, manufacturers use grey cast iron for cylinder blocks
while sometimes adding nickel and chromium. Nowadays, they also use
aluminum to reduce weight and improve performance. However, the
aluminum blocks use cast-iron or steel sleeves on cylinders. Most
engines prefer cast-iron for cylinder walls as it has lower wearing
qualities. Some small engines use chromium for plating cylinder
walls to reduce wear & increase service life.
Manufacturers are conducting tests on silicon-aluminum alloys for
their use in cylinder blocks. These alloys have a low coefficient
of thermal expansion and high wear resistance. Besides, aluminum
alloy blocks maintain more uniformity of temperature because of
their thermal conductivity. Often, manufacturers use the block,
head, and crankcase made of aluminum alloy. Grey cast-iron for the
block is the same that is used for the head. However, aluminum
alloys are usually quite different. Cast iron is still used for
heavy applications such as commercial engines, rail- engines and
marine engines.
