The liner guides the piston in its vertical motion. It must withstand the extreme heat and pressure developed within the combustion space at the top of the cylinder, at the same time, permitting the piston and its sealing rings to move with minimum friction, hence high hardness level is essential.

AEC cylinder liners that are made of high grade heat treated cast iron ensure high hardness level and long usage.

Liners within the AEC range, which are phosphate coated, possess exceptional resistance against corrosive properties of the coolant, maintaining te functionality of the engine. The inner Plateau Cross Hatch Design ensures high tensile strength, reduces initial wear, grain emission and shorter run in time.

Stringent manufacturing tolerances allow perfectly around bores for efficient oil control and proper fit into engine blocks.
