| Abstract:In order to improve the performance of high-power middle-speed marine diesel engines, especially in low operating conditions，the research on the control system of sequential turbocharging which has intake and exhaust bypass and high load waste-gate system was carried out. The whole structure, system function and working flow of the developed control system is introduced in detail. Programmable logic controller (PLC) was adopted to achieve good controlling function. The tests results show that the developed control system reaches the design objective, and is safe and reliable in operation. |
| Key words: middle-speed marine diesel engine sequential turbocharging control system PLC |
