采用ＭＰＣ－相继增压系统来改善船用柴油机低负荷性能，提高其经济性。应用“改进容积法”，建立了ＭＰＣ－相继增压柴油机的计算模型，并编制了计算程序，对ＰＡ６－２８０柴油机采用该系统进行了理论计算，计算结果与法国同机型试验结果基本吻合，并在１２ＶＰＡ－２８０柴油机上进行了试验研究。试验结果表明，采用该系统，ＰＡ６－２８０柴油机在（４００～７００）ｒ／ｍｉｎ时，柴油机功率平均提高到２５０％，烟度降低了６６％，涡轮进口温度降低３０％，取得了较好的效果，改善了船用柴油机低负荷性能。
Adopt MPC-sequential booster system to improve low-load performance of marine diesel engine and improve its economy. The calculation model of MPC-turbocharged diesel engine was established and the calculation program was compiled. The theoretical calculation was carried out on the PA6-280 diesel engine using the system. The calculated results are in good agreement with those of the French model test. And 12VPA-280 diesel engine on the pilot study. The test results show that with this system, the average power of diesel engine is increased to 250% at 400 ~ 700 r / min for PA6-280 diesel engine, the smoke density is reduced by 66% and the turbine inlet temperature is reduced by 30% Effect, improving the low load performance of marine diesel engine.
