Abstract
An apparatus includes an internal combustion engine with an engine block and a cylinder liner housing a piston. The engine block includes at least one cylinder cavity and at least one replaceable cylinder liner positioned within the cylinder cavity. At least two press fit areas create an interference fit between the engine block and the replaceable cylinder liner. One press fit area is located proximate to the top surface of the engine block and the other press fit area is located in the engine block at the opposite end of the cylinder liner. A storage volume is formed between the press fit areas by the outer surface of the cylinder liner and the surface of the engine block defining the cylinder cavity.
