Engine Cylinder Block

What is an Engine Cylinder Block?

Does your vehicle’s engine contain more than one cylinder? In case of a multi cylinder engine, you will find that all cylinders are cast in a block, which is known as the cylinder block of that engine. The main purpose of this type of block is to support all cylinders in a single block. You may find any one of the following types of cylinder block in your engine.

- Wet liner block
- Dry liner block

In case of a dry liner block, you will find a discrete liner inserted into the engine block that forms the supporting part of the cylinder wall. You will also find additional sleeves, which do not come in contact with the engine coolant. However, if your engine’s cylinder block is in the wet liner category, then you will find cylinder walls, which can be removed entirely. These cylinder walls fit into the engine by means of very special gaskets that can easily withstand high temperature.




You should remember that, in this type of block, liners come in direct contact with the engine coolant. In both wet and dry liner cylinder blocks, you can totally replace or remove liners, while overhauling or rebuilding without replacing the engine block. Practically, it is so tough to remove or install these liners. So, you are advised to never undergo such a procedure within the lifespan of that engine.
