Wet liner cylinder blocks use cylinder walls that are entirely removable and fit into the block using special gaskets. They are called "wet liners" because their outer sides come in direct contact with the engine's coolant. In other words, the liner is the entire cylinder wall, rather than merely a sleeve.
Cylinder liners (also known as sleeves) are thin metal cylinder-shaped parts which are inserted into the engine block to form the inner wall of the cylinder. [4] [5] Alternatively, an engine can be 'sleeveless', where the cylinder walls are formed by the engine block with a wear-resistant coating, such as Nikasil or plasma-sprayed bores.
The liners were only loosely installed into the block with hand pressure. The sealing of the liners into the engine block was at the bottom by a pair of soft metal "spectacle washers" [4] that each sealed a pair of liners. Each liner stood slightly proud of the cylinder block face. [5] so that it formed a good seal against the head gasket when ...
The cost of the replacement component (i.e. the head gasket itself) is usually relatively low, however there are significant labor costs involved in the replacement process. [6] This is because the process of removing and replacing the cylinder head is a time-consuming task.

It is predominantly known for its use in coating the cylinder bores of an internal combustion engine, enabling the construction of aluminium engine blocks without cast iron cylinder sleeves. The inventors of PTWA received the 2009 IPO National Inventor of the Year award. [ 1 ]

A sleeve valve takes the form of one (or in the case of double sleeve valves, two) machined cylinders which fit concentrically between the piston and the cylinder block bore of an internal combustion engine having cross-flow induction/exhaust. These sleeves have inlet and exhaust ports machined in the periphery, analogous to a two-stroke motor ...
