439WN0101 MAHLE Cylinder Liner

MAHLE's Cylinder Component is a crucial part for the crankcase of an engine, where it serves as a cylinder liner. This component enhances thermal conductivity and minimizes oil consumption, thereby boosting engine efficiency and extending its lifespan. With dimensions of 303.0 x 154.0 x 154.0 mm and originating from Austria, this product is identified by MPN 439WN0101. Dimensions are provided by the supplier and may include packaging dimensions. Cylinder liners are precision-honed, tubular components installed within the engine block to create the combustion chamber’s sealing surface. Typically utilized in heavy-duty and high-performance engines, they provide a durable, replaceable wear surface for piston travel. Liners are constructed from cast iron, steel, or coated alloys, optimized for heat dissipation and minimizing friction. Wet liners are directly cooled by engine coolant, while dry liners rely on the block for thermal management. Precise dimensional control and surface finish are critical for maintaining compression and preventing oil consumption.
