摘要
通过测试不同工况下的高压油管嘴端压力和喷油器针阀升程,研究了不同配比生物柴油对柴油机喷射过程的影响.实验研究表明:在供油提前角、转速和负荷相同的情况下,随着燃料中生物柴油含量的增加,高压油管最大喷油压力增加,喷射延迟期和喷射持续期变长,导致循环喷油量增大.
The line pressure at injector side and nozzle needle lift were measured to evaluate the injection process of different mixing ratios of a bio-diesel. The measured results show that the peak pressure is higher, the injection delay and duration exhibit a slightly longer, which made a higher fuel-injection percylinder cycle, at the same fuel delivery advance angle, engine speed and load, when the bio-diesel ratio increases.
