Internal combustion engine's crankcase manufacturing method, involves applying ceramic composite material units as mosaic interlacing on surface of combustion chamber wall of internal combustion engine by using foil

摘要

The method involves applying ceramic composite material units (2) as a mosaic interlacing on a surface of a combustion chamber wall (1) of an internal combustion engine by using a foil, and pressing the material units into the wall with high pressure. The material units and the wall are locally heated by a fiber laser, and the wall with the material units is planed by a grinding device, where the material units are made from carbon fiber-reinforced silicon carbide and comprise longitudinal extension in a size range of 1 to 5 mm. Independent claims are also included for the following: (1) a device for manufacturing a crankcase of an internal combustion engine (2) a crankcase of an internal combustion engine comprising a combustion chamber.
