    摘要： An exhaust system for a personal watercraft provides an exhaust adapter plate and an exhaust header pipe that allows exhaust to exit from the rear of a horizontally mounted internal combustion engine. The exhaust adapter plate is mounted to the rear of the engine block. The exhaust adapter plate has openings corresponding to the engine exhaust port and engine cooling water jacket. The adapter plate also has an opening for the engine crankshaft. The exhaust header pipe is mounted to the engine with the adapter plate disposed therebetween. An exhaust passage through the exhaust header pipe passes transversely across the engine compartment within the watercraft. As the exhaust header pipe passes transversely across the engine compartment, the exhaust passage angles upwardly from the exhaust adapter plate to a high point, and angles downwardly from the high point to an exhaust outlet leading to a muffler. The exhaust passage through the exhaust header pipe is tuned, yet the configuration of the exhaust header pipe provides a compact design that is easily packaged within the engine compartment for a personal watercraft, and also provides for sufficient space rearward of the exhaust header pipe so that the exhaust system and the remainder of the engine can be easily serviced. Also, since the exhaust header pipe and the exhaust adapter plate are physically separate components, each can be designed to be manufactured using simpler manufacturing techniques.

    摘要翻译： 用于个人船舶的排气系统提供排气适配器板和允许排气从水平安装的内燃机的后部排出的排气集管。 排气适配板安装在发动机缸体的后部。 排气适配器板具有对应于发动机排气口和发动机冷却水套的开口。 适配器板还具有用于发动机曲轴的开口。 排气总管安装在发动机上，其中适配器板位于它们之间。 通过排气集管的排气通道横向穿过船舶内的发动机室。 当排气集管横向穿过发动机舱时，排气通道从排气适配器板向上倾斜到高点，并从高点向下通向通向消声器的排气出口。 通过排气总管的排气通道被调节，但是排气集管的构造提供了一种紧凑的设计，其易于包装在用于个人船舶的发动机室内，并且还提供了排气集管的后面的足够空间，使得 排气系统和发动机的其余部分可以方便地维修。 此外，由于排气集管和排气适配器板是物理上分离的部件，因此可以使用更简单的制造技术来设计。

    摘要： A "lost foam" method of making a casting having a preform embedded at a selective location therein including the steps of: engulfing a porous preform in a fugitive pattern; embedding the pattern in a loose sand mold in a vessel; pouring molten metal into the mold cavity via a sprue and runner system formed in the sand bed so as to destroy the pattern and fill the mold cavity with metal; pressurizing the vessel to force molten metal from the cavity into the porous preform; replacing metal lost from the cavity with make-up metal from the sprue and runner system; allowing the casting to solidify; and removing the casting from the sand bed.

    摘要： A cast tubular structure including an integral hose connection element formed thereon is produced by lost foam casting wherein a circular socket seat is formed on a pattern for a body portion of the cast tubular structure and a cylindrical pattern for the integral hose connection element is formed by a mold without vent openings on the mold surface in the area of the cyclindrical pattern corresponding to the hose sealing surface of the cast tubular structure. The pattern sections are joined with the pattern section for the hose connection element sealing within the circular socket seal formed in the body portion of the cast structure. The pattern assembly is coated with a slurry and, after drying, is placed in a casting flask. Molten metal is then poured within the coated pattern assembly dissolving the foam patterns and forming the cast tubular structure.
