摘要
以改善大功率中速船用柴油机性能,尤其是低工况性能为目的,研制了带进排气旁通和高工况放气阀的相继增压控制系统。详细介绍了该控制系统的整体结构、系统功能、工作流程等。采用可编程逻辑控制器(PLC)实现控制系统功能。试验验证表明:所研制的控制系统达到设计要求,工作安全可靠。
In order to improve the performance of high-power middle-speed marine diesel engines, cially in low operating conditions, the research on the control system of sequential turbocharging espe- which has intake and exhaust bypass and high load waste-gate system was carried out. The whole structure, sys- tem 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 devel- oped control system reaches the design objective, and is safe and reliable in operation.
