MIXPC exhaust manifold structure、large scavenging overlap angles and inlet valve open timing ahead are three basic features of this turbocharging system. The reason why MIXPC-SCABY turbocharging system can improve engine's partial load performance much more than any other ordinary turbocharging system is because the increase of the scavenging air amount at partial load exceed much of that at rating condition. Simulation study was carried out on 16VPA6-280、8L250Z、16V280ZJA diesel engines with MIXPC-SCABY turbocharging system, the results show that Pmax、BSFC are decreased and partial load performance is improved, scavenging interference is also avoided. Besides, MIXPC-SCABY turbocharging system is easy to put into practice because of no any extra control equipment, and NOx emission can also be decreased because of its low temperature cycle.

By computational analysis, it was found that the crank angle of scavenging port opening, the crank angle of exhaust port opening and the scavenging port circumferential angle influenced the charging efficiency obviously. And the charging efficiency became smaller as the three parameters increased. Thus it led to power decrease. Although the escape ratio decreased rapidly as the crank angle of exhaust port opening increased, it was advantageous in the engine emissions.
分析发现，扫气口开启角度、排气口开启角度和扫气口圆周角对充量系数影响较大，随着这3个量的增加，充量系数下降，扫气效果变差，导致功率下降；同时随着排气口开启角度的增加，逃逸比迅速减小，有利于排放。
