The demand for efficiency and sustainability mean a reduction in friction and wear for modern combustion engines. A significant contribution to this is the laser honing developed by Gehring, which is now used worldwide in the series production of cast iron cylinder crankcases. In both diesel and gasoline engines, laser structuring of the cylinders is currently carried out in the area of the upper piston reversal point.
The combination of laser structuring and honing of cylinder running surfaces is understood as laser honing.
