喷油系统参数对重型车用增压直喷柴油机NO_x排放的影响

Effects of Fuel Injection System on NO_x Emission from a Heavy-Duty Turbocharged Automotive DID Engine

本文针对一台重型车用增压中冷电控直喷式柴油机,试验研究了喷油系统参数如喷孔直径、喷孔锥角、喷油压力、喷油定时等对NO_x排放和排气烟度的影响,指出了通过它们的优化匹配,改善柴油机排放特性的途径。

Effects of fuel injection system parameters such as injector nozzle hole diameter, nozzle hole cone angle, injection starting pressure, and injection timing on NOx emission and soot emission from a turbocharged and inter-cooled. electronically controlled heavy-duty automotive DID engine were experimentally studied, indicating the way to improving NOx emission of the engine by optimization of fuel injection system.
