The steadily rising demands on internal combustion engines require continuous improvements in the area of cylinder working surfaces. The precise matching of the honed cylinder liners with the pistons and piston rings leads to improved results in the engine.
For cylinder liners made from cast iron, it is therefore necessary to create optimum surfaces that contribute to lower oil consumption and blow-by, produce fewer wear particles and allow shorter running-in times and consequently a longer service life.
MAHLE manufactures cylinder liners for international engine manufactures for series production and the aftermarket – always according to the same strict quality standards. We manufacture our cylinder liners with very strict tolerances. This ensures, among other things, that the cylinder liners can be optimally fitted into the engine block. Additional important quality characteristics of our cylinder liners are the materials, the structure and the surface quality. In close cooperation with engine manufacturers, we determine the composition of the melt, the treatment of the melt and the machining process.
