WATER COOLED EXHAUST MANIFOLD

摘要

A modular exhaust manifold includes a plurality of exhaust manifold segments coupled together along a common axis. Exhaust manifold segments include a water jacket tube defining a liquid coolant passage around each of the plurality of exhaust manifold segments. The internal combustion engine also includes a coupling assembly for joining adjacent exhaust manifold segments. The coupling assembly includes a plurality of annular sealing devices configured to fit within a first set of grooves formed on an end portion of a first exhaust manifold segment. The coupling assembly also includes a spacing collar configured to attach to the end portion of the first exhaust manifold segment and couple with a fixed radial flange formed on an adjacent end portion of a second exhaust manifold segment to join the first exhaust manifold segment and the second exhaust manifold segment.

1. An internal combustion engine, comprising:
a cylinder block defining at least one cylinder; a cylinder head coupled to the cylinder block; and a modular exhaust manifold coupled to the cylinder head and configured to receive exhaust gas from the cylinder head, wherein the modular exhaust manifold includes a plurality of exhaust manifold segments coupled together along a common axis, and wherein each of the exhaust manifold segments includes a separate a water jacket tube defining a separate liquid coolant passage around each of the plurality of exhaust manifold segments; and a coupling assembly for joining adjacent exhaust manifold segments, the coupling assembly including a plurality of annular sealing devices configured to fit within a first set of grooves formed on an end portion of a first exhaust manifold segment and a spacing collar configured to attach to the end portion of the first exhaust manifold segment and couple with a fixed radial flange formed on an adjacent end portion of a second exhaust manifold segment to join the first exhaust manifold segment and the second exhaust manifold segment.
