Does the new engine have cylinder liners?

[BrooklynAnn]

Not all engines are equipped with cylinder liners. Introduction to Cylinder Liners: A cylinder liner is a cylindrical component installed within the cylinder block bore of the engine, secured in place by the cylinder head. The piston reciprocates inside its inner bore, while the exterior is cooled by circulating water. Functions of Cylinder Liners: Together with the cylinder head and piston, they form the working space of the cylinder; In trunk-piston diesel engines, the cylinder liner bears the side thrust from the piston, serving as the guide for the piston's reciprocating motion; They transfer heat from the piston assembly and themselves to the cooling water to maintain an appropriate operating temperature; In two-stroke diesel engines, the cylinder liner is equipped with ports that are opened and closed by the piston to achieve gas distribution.
