Description
What is the Engine Block?
The engine block is the collective term that refers to the
crankcase and all the components that fill it, including gaskets,
valves, and seals. Because of its importance in the functioning of
the car, drivers should perform regular maintenance on their
vehicles to prevent damage to internal parts that can be caused by
overheating, insufficient oil, and other easily preventable
situations.
What is the core of the engine block?
The core of the engine block is the cylinders, capped by the
cylinder head. The number of cylinders determines the size and
placement of the block, with most cars having between four and
eight cylinders. These cylinders house pistons, which provide
motive energy for the vehicle through a series of controlled
explosions inside the cylinders which push the pistons out, moving
the crankshaft of the vehicle.
How Is an Engine Block Made?
The engine block is the metal housing containing the inner workings
of an internal combustion engine. It is of critical importance to
the operation of your engine. If the engine block cracks, your car
should not be driven until it is repaired or replaced.
Material
Engine blocks were traditionally made from cast iron, but in the
interest of better fuel mileage, lighter aluminum alloys have been
introduced. The metal is heated to 800 degrees C and then poured
into a sand mold where it hardens and sets.
Sand Casting
The sand molds used to cast engine metal can be used only once.
Zircon sand, glue and a hardener are mixed and shaped into
sections. This is then solidified with gas. The sections are glued
together to form the entire mold in which the engine block is cast.
Casting and Machining
Once the liquid alloy is poured into the mold and has set, the mold
is heated to break down the glue that solidifies the sand. The sand
will then pour off of and out of the hardened engine block. Tooling
equipment machines the engine blocks before they are inspected and
sent to engine assembly plants where final machining is done before
engine assembly.
