Description
What is an Engine Block?
The engine block is the linchpin of vehicles that run on internal
combustion, providing the powerhouse for the vehicle. It is called
a "block" because it is usually a solid cast car part, housing the
cylinders and their components inside a cooled and lubricated
crankcase. This part is designed to be extremely strong and sturdy,
because its failure results in failure of the car, which will not
function until the engine block isreplaced or repaired.
Working from the outside in, this part starts with a solid metal
outside, designed to seal everything inside. A number of channels
and passages inside comprise the cooling jacket and are designed to
deliver water from the radiator to all the hot sections of the
engine, preventing overheating. After the water is circulated in
the engine, it returns to the radiator to be cooled by the fan and
sent back through the engine.
What Is the Purpose of an Engine Block?
1. Foundation. The engine block provides a foundation for the
crankshaft and all other engine components.
2. Pistons. Additionally, the engine block contains the cylinders
housing the pistons, which provide motive energy.
3. Passages and Surfaces. It provides oil and coolant passages,
sealing surfaces and flat surfaces for the engine heads.
4. Cooling.
5. Oil Pan.
Parts of an engine block
1. Cylinders. Cylinders are spaces in which the pistons travel.
2. Coolant. When the engine is running, the cylinder walls get
extremely hot - and deliberately so; one of their core functions is
to carry heat away from the piston.
3. Oil passages.
4. Deck.
5. Crankcase.
How are engine blocks cast?
All blocks, with the exception of extremely specialised ones, are
cast by pouring molten metal into molds. Historically engines were
cast using iron, but increasingly aluminium alloy is used due to
its lighter weight.
What is used Engine Block?
Used Engine Blocks. An engine block, sometimes referred to as a
cylinder block or motor block, is a metal casting, usually made
from iron or aluminum alloys. The engine block houses the engine
cylinders and the upper part of the crankcase. Various engine
components are attached to the engine block, including the water
pump, valve head and crankcase.
