摘    要:为了以较低的成本降低中速大功率船用柴油机的NOx排放,开发了一种可实现靴型燃油喷射规律的调压孔武喷油泵.利用三维CFD软件AVL FIRE v8.5对某大功率中速船用柴油机的缸内流动、混合气形成和燃烧过程进行了模拟计算,分析了调压孔式喷油泵的靴型喷射规律在2种负荷、3种喷油定时下对柴油机性能和排放的影响.结果表明:所用...

关 键 词:柴油机  靴型喷油率  性能  排放

Abstract:To reduce the NOx emissions from medium speed marine diesel engines with low costs,a pressure-modulating-hole type fuel pump was developed,which could provide boot-type injection rates.3D CFD package AVL FIRE v8.5 was used to simulate the in-cylinder gas flow,fuel-air mixing and combustion processes of a medium speed,high-power marine diesel engine.And the effects of the boot-type injection rates provided by the new pumps on the performance and emissions at 2 loads with 3 injection timings of the engine wer...
Keywords:diesel engine  boot-type injection rates  performance  emissions
