Abstract

An exhaust manifold cooling jacket (20) has internal passages (30) for the circulation of liquid coolant and encloses an exhaust manifold such that a gap (31) is created between the exhaust manifold and cooling jacket (20). Flowing coolant through the jacket (20) regulates outer jacket temperature while enabling high intra-manifold exhaust gas temperature for thorough intra-manifold combustion and improved emissions. In some marine applications, for example, seawater coolant is discharged into the exhaust gas stream at an attached exhaust elbow.
