He has made significant contributions to the field of engineering, particularly in the development of advanced materials for engine components. With a total of 3 patents to his name, Rieger's work focuses on enhancing the performance and durability of cylinder liners in reciprocating piston engines.

Latest Patents

Rieger's latest patents include innovative designs for cylinder liners made from supereutectic aluminum/silicon alloys. One of his patents describes a cylinder liner that is free of mixed-in particles of hard material. This design allows for the automatic formation of fine silicon primary crystals and intermetallic particles from the melt, resulting in hard particles that enhance wear resistance. The process involves spray compaction of finely sprayed melt droplets, leading to a fine distribution of hard particles. This innovation not only improves the contact area of the surface but also ensures gentle treatment of the piston and its rings.

Another patent focuses on a cylinder liner of a hypereutectic aluminum/silicon alloy. This design also emphasizes the absence of mixed-in hard particles and incorporates a cold extrusion process to create a shape that approximates the cylinder lining. The surface is then fine machined and honed, exposing hard particles that project above the base microstructure. This meticulous process enhances the durability and performance of the cylinder liner.
