Water cooled turbocharged diesel engine - has water cooled header plate on exhaust pipes entering turbocharger

摘要

The marine diesel engine has an exhaust manifold (3) from several cylinders surrounded by a common insulating jacket (12). This prevents heat from the exhausts endangering nearby fuel lines or maintenance personnel. The exhaust manifold is brought together to supply the turbine of an exhaust driven turbocharger. At the point of connection to the turbocharger, the separate exhaust pipes are held in a header plate (2). This has water cooling channels (7) in it between the pipes. The insulating jacket (11) is screwed to the header plate (2) which provides a gas tight joint on the end of the insulating jacket and reduces its.
