Experimental Investigations for Improvement of Oil Control for an Orbiting Sealing Application

Prime candidates for cleaner propulsion are the non-reciprocating combustion engines that combine high efficiencies of volumetric engines while being well-known for their high power density. Unfortunately, these engines are also well-known for their oil consumption that needs to be reduced before they are used for aerospace applications in order to meet customer perceptions, weight and forthcoming emission regulations. The first targets are to address leakage through the face-sealing Oil Control Rings (OCRs) and injected oil spilling away from the gas seals as they can be drastically reduced from current values without a significant impact on engine durability. This proposed project aims at reducing oil consumption through the development of improved OCRs and injection strategy.
