20160024986 | MARINE EXHAUST VALVING - A marine engine exhaust system includes a catalyst arranged to intercept a flow of exhaust flowing along the exhaust system, a water muffler downstream of the catalyst, and a water-activated exhaust valve disposed between the water muffler and an upstream catalyst and configured to impede flow of water upstream from the muffler to the catalyst. | 01-28-2016 |
20130142703 | CONTROLLING EXHAUST TEMPERATURES - An exhaust manifold cooling jacket has internal passages for the circulation of liquid coolant and encloses an exhaust manifold such that a gap is created between the exhaust manifold and cooling jacket. Flowing coolant through the jacket regulates outer jacket temperature while enabling high intra-manifold exhaust gas temperatures for thorough intra-manifold combustion and improved emissions. A liquid-cooled exhaust system includes a turbocharger disposed between manifold and elbow, with liquid coolant flowing from manifold to elbow through the turbocharger. Another liquid-cooled exhaust manifold contains an internal exhaust combustion catalyst wrapped in an insulating blanket. In some marine applications, seawater or fresh water coolant is discharged into the exhaust gas stream at an attached exhaust elbow. | 06-06-2013 |
