| Abstract: | Diesel engine must meet all performance requirements in work conditions as the Marine engine. In order to improve the performance in low operating conditions, Sequential turbocharging system has been designed. Design objective which is small volume, simple structure, easy to repair, high reliability is achieved. On the basis of the model, the STC diesel engine has been calculated, the sequential turbocharging switch point is determined. Then based on the experimental study of propeller characteristics, limiting characteristics and universal characteristics f the diesel after transformed, the changes of power and economic on working conditions of 1TC and 2TC when the diesel works in the different conditions has been analyzed. |
