Outboard marine propulsion devices and methods of making outboard marine propulsion devices having exhaust runner cooling passages |
摘要 |
An outboard marine propulsion device comprises an internal combustion engine. At least one engine cooling passage conveys cooling water through the internal combustion engine. An exhaust manifold comprises a plurality of exhaust runners and an exhaust log. The plurality of exhaust runners axially conveys exhaust gases from the internal combustion engine to the exhaust log. A cooling jacket on the exhaust manifold comprises an exhaust log cooling jacket that conveys the cooling water along an outer surface of the exhaust log and a plurality of exhaust runner cooling passages that each axially convey the cooling water along an outer surface of a respective one of the plurality of exhaust runners from the exhaust log cooling jacket to the engine cooling passage. |

1. An outboard marine propulsion device comprising:
an internal combustion engine; at least one engine cooling passage that conveys cooling water through the internal combustion engine; an exhaust manifold that comprises a plurality of exhaust runners and an exhaust log, wherein the plurality of exhaust runners axially conveys exhaust gases from the internal combustion engine to the exhaust log; and a cooling jacket on the exhaust manifold, wherein the cooling jacket comprises an exhaust log cooling jacket that conveys the cooling water along an outer surface of the exhaust log and a plurality of exhaust runner cooling passages that each axially convey the cooling water along an outer surface of a respective one of the plurality of exhaust runners from the exhaust log cooling jacket to the at least one engine cooling passage. |
