With higher brake mean effective pressure (BMEP) of a diesel engine, pistons and cylinder liners suffer from increasing mechanical and thermal loading which causes several problems on these engine parts. The main critical problems are thermally induced cracking on the piston head and scuffing on the cylinder bore. Hard anodizing the piston head is described. It is currently the most effective countermeasure against heat cracking. Another promising method, to reinforce the piston head by means of SiC-whiskers, is also reported. A new process for improving the surface lubrication of the cylinder liner was developed. The bore has numerous finely distributed micropits which act as good oil reservoir. This improves the antiscuffing property of the cylinder liner.
