  • Durable high performance water-cooled exhaust systems and components
    Patent number: 11225891
    Abstract: An exhaust component for an engine exhaust system includes a conduit for carrying exhaust gases, an outer wall, a fluid inlet, a fluid outlet, and a pattern of internal support structures. The conduit, outer wall, and internal support structures are formed from an additive material using an additive manufacturing process. A water cavity is defined between the conduit and the outer wall. The fluid inlet and outlet are in fluid communication with the water cavity. The pattern of internal support structures are integral with the conduit and with the outer wall, are disposed in the water cavity, and are arranged such that fluid flows from the fluid inlet through, between, or around the internal support structures to the fluid outlet. The fluid and its flow through the water cavity is adapted to absorb heat from hot exhaust gases flowing through the conduit during operation of the engine exhaust system.
