Abstract

To study the injection characteristics the double-solenoid valve system is designed in different conditions, and double solenoid valve test system and a test platform and built to complete the test content. Conditions on the regulation of the same target features, performance and low-speed jet loop dynamic adjustment of performance between the test result analysis. Results show that double solenoid valve system on the same target conditions can be quickly and easily change the injection characteristics, enhanced fuel injection characteristics of the controllability of the system, through the two valves are open and flexible combination of timing control, low speed engine, they can easily achieve high-pressure fuel injection, by changing the control valve and the duration of time, two-valve system can be quickly and flexibly adjust the diesel engine fuel injection characteristics of each work cycle to meet the needs of the engine in different conditions, can greatly improve engine performance and low speed start-economy and emissions.

双阀控制系统特性的实验研究

为研究双电磁阀喷射特性，设计了不同工况下的双电磁阀系统，并搭建了双电磁阀测试系统和测试平台，完成了测试内容。对调节条件相同的目标特性、低速射流回路动态调节性能与试验结果之间的关系进行了分析。结果表明，双电磁阀系统在相同目标条件下可以快速方便地改变喷射特性，增强了系统燃油喷射特性的可控性，通过双阀的开启和灵活组合进行正时控制，在发动机低速时，它们可以轻松实现高压燃油喷射，通过改变控制阀和持续时间;双气门系统可以快速灵活地调整柴油机各工作循环的燃油喷射特性，以满足发动机在不同工况下的需要，可以大大提高发动机低速启动经济性和排放性能。
