| Abstract: | This paper changed the automotive diesel engine to the speedboat, taking the rated conditions of diesel engine as the design conditions. For the working characteristics-the speedboat advancing of the engine cooling system, the paper takes modified design to water cooler and intercooler respectively, the key design processes and methods of computation were determined. Then it compared experimental values and theoretical values, and analyzed deviations. The experimental results prove that the design meets the cooling requirements of speedboat diesel. |
