| 摘要 |
Exhaust cooling system for a marine engine which prevents any heat corrosion deterioration of the exhaust pipe and elminates substantially all air pollution from the exhaust; the system includes a water spray element immediately adjacent to the exhaust manifold which injects spiraling divergent, crossing water sprays about 360 DEG of the element's circumference at the very beginning of the exhaust system by means of a basic wafer structure interposed between and in line with the manifold and the exhaust pipe; two embodiments are disclosed, one designed for insertion between flanges and the other for insertion between a screw thread/flange joint; the water sprays cool down the exhaust sufficient to allow touching of the exhaust pipe throughout its length and absorb practically all of the solid pollutants in the exhaust fumes.
