The cylinders of a combustion engine from the working space and
combustion chamber. The cylinders are also charged with the task of
guideline pistons as they move up and down and directing the heat
generated during the combustion process to the cooling system. The
cylinder wall is wetted with oil to ensure sufficient lubrication to pistons and
piston rings moving up and down inside the cylinder.
Appropriate materials are selected to safeguard good heat transfer to the
engine block or coolant. Depending on their design, cylinders can be made
from different alloys of grey cast iron and may be Air Cooled, Air Cooled,
Full or Semi Finish.
