Cylinder liner
The cylinder liner is one of the important functional parts that is integrated with the engine block and forms the combustion chamber.
In order to make our product accommodate to various types of engine blocks,we have our product lineup categorized into basic three types; cast-in cylinder liner, thin-wall-dry liner and wet liner.
Cast-in cylinder liner - Patented technology

- 【Features】
- This is a type which is molded as an integral structure with aluminum engine block.
- We can manufacture this type of liner at lower cost by centrifugal casting method.
- AsLock® cylinder liner has better adhesiveness to aluminum than conventional cast-in cylinder liner through the constricted-shaped projections on its surface.
- AsLock® cylinder liner is categorized into two types, Compared to AL-13, ALH150 has a lower protrusion height and higher protrusion density, so it has the effects of reducing the bore pitch and improving heat transfer from the liner to the engineblock.
Therefore, ALH150 is effective for increasing the size and output of the engine.
- 【Main Products】
- Gasoline and Diesel Engine (Aluminum Block)
Thin wall dry liner

- 【Features】
- This is a type which is manufactured by pressure casting process.
- Outer surface of the liner contacts with the engine block and does not contact in direct with the engine coolant.
- This type of liner can achieve downsizing and weight saving of engines because it can make bore clearance smaller by its thin design.
- We can also provide you with liners manufactured with phosphate coating for improving abrasion resistance.
- 【Main Products】
- Medium/Large-sized Diesel Engine
- Motor sports Engine
Wet liner

- 【Features】
- This is a type which is manufactured by pressure casting process.
- Outer surface of the liner is a part of the water jacket.
- We can also provide you with liners with chrome plating or other kinds of coating onto outer surface for preventing cavitation.
- 【Main Products】
- Medium/Large-sized Diesel Engine
