    • An exhaust gas cooling system for an engine includes an exhaust gas conduit having an inner tube defining an exhaust gas passage and an exhaust coupler surrounding the inner tube and defining a cooling water passage together with the inner tube therebetween, and a water-lock coupled with a downstream end of the exhaust gas conduit through an exhaust gas conduit coupling section which extends from an upstream end of the water-lock. The exhaust gas conduit coupling section and the exhaust coupler are coupled with each other and the inner tube extends into the interior of the water-lock. A downstream end part of the inner tube can be formed to be a wide portion having a bell mouth configuration. A diameter of the downstream end part becomes larger as a portion thereof exists closer to the end of the downstream end part. The exhaust gas cooling system for the engine can be provided for a water vehicle.

    • A cooling system particularly suited for use in a small watercraft, which supplies coolant to, and evacuates coolant from, an engine of the watercraft. The engine includes an engine body defining at least one water jacket therein. An engine coolant supply passage desirably routes the coolant into thermal communication with a portion of an exhaust system, such as an exhaust manifold, before supplying the coolant to the water jacket of the engine. When the engine is shut off, coolant is permitted to drain from the water jacket through a drain passage. The drain passage is connected to the coolant supply passage at a position upstream from the exhaust system such that coolant draining from the engine travels in a reverse direction through the supply passage and is drained from the watercraft cooling system. Upon normal operation of the engine, a restriction orifice within the drain passage permits only a relatively small amount of coolant to be supplied to the engine water jacket, without being routed into thermal communication with the exhaust system.
    • 一种特别适用于小型船舶的冷却系统,该系统向船只的发动机提供冷却液,并从其中抽出冷却剂。 发动机包括在其中限定至少一个水套的发动机主体。 发动机冷却剂供应通道期望在将冷却剂供应到发动机的水套之前使冷却剂与诸如排气歧管的排气系统的一部分热连通。 当发动机关闭时,允许冷却剂从水套通过排水通道排出。 排水通道在排气系统上游的位置连接到冷却剂供应通道,使得从发动机排出的冷却剂沿相反方向通过供应通道行进并从船只冷却系统排出。 在发动机正常运行时,排水通道内的限流孔仅允许相对较少量的冷却剂供给发动机水套,而不会与排气系统进行热连通。
