Technical Tips – Engine Blocks

The engine block is the heart of the engine because it is the most fundamental part of it. The engine block is the structure in which all the elements of the engine are located: cylinders, pistons and others.

The main function of the engine block is to house the most important parts of the engine. This piece contains the orifices for the cylinders and within it the pistons work to burn the fuel. One of the functions of the cylinder block is to supply the main line of oil to the most important parts of the engine.

What is the engine block made of

The two most used materials to manufacture the engine block are: cast iron or aluminum. The advantage of cast iron is that it has a resistance proportional to its volume, but it is heavier.

The manufacture of an engine block

The engine block is manufactured from a mold that is created from a mixture of zircon sand, glue and hardener. Zircon sand has a very high melting point, so it is ideal for this task. The sand mixture is injected into the master mold and solidified through a gas. The different molds are glued to each other using a glue capable of withstanding high temperatures. Once the entire mold is ready, all the material from which the engine will be made of is injected into it.

What are the parts of an engine block?

Cylinders are the place where the pistons are located, which in turn generate the movement of the engine with the explosions. Cylinders can come in different sizes, but these are determined by the stroke or size of the piston.

Cooling channels

The passages of the block are the channels through which the water circulates. These channels are found around the cylinders and their design helps dissipate heat when in contact with the liquid, but helping to maintain the resistance of the walls.

Crankshaft

The crankshaft is located at the bottom of the engine block where the connecting rods are mounted.
