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.
