| Abstract: | The factors those influence gas pressure fluctuation in intake and exhaust pipes as well as exhaust energy using in a boost diesel engine have been analyzed in this paper. Based on the working process calculation for the cylinder of the boost diesel engine, a calculation program on pressure fluctuation in intake and exhaust pipes was compiled. Pressure fluctuation in intake and exhaust pipes of the boost diesel engine was calculated by the program. We investigated the effect of different length of intake and exhaust pipes on airflow, when 4102BZLQ diesel engine operated in rating speed, and put forward an improvement suggestion on the design of intake and exhaust pipes of the 4102BZLQ diesel engine. A simple and effective calculation method on dimensions of intake and exhaust pipes was suggested. |
