| 摘 要： | 介绍了数字电位器X9221的结构、工作原理及特点，利用数字电位器X9221与单稳态触发器14538组成脉宽控制电路控制液化石油气喷射时间，设计了柴油—液化气双燃料发动机电控系统。由于X9221存储数据的不易丢失性，系统的可靠性得到提高。同时，系统具有结构简单、调节方便等特点。该电控系统的应用大大改善了机组的废气排放性能。

| Abstract: | E2POT Nonvolatile Digital Potentiometer is a typical one among the Digital Potentiometers of Xicor company's products. The characteristics, working principle, and the technology of using E2 POT Nonvolatile Digital Potentiometer in electronic fuel injection for the dual-fuel engine for power unit of irrigation machinery were introduced. The injection pulse length was controlled hy using an anti-lose-easily rheostat X9221 and a monostable trigger 14538. Due to the anti-lose-easily characteristic of X9221, the ECU is more reliable. At the same time ECU has the features of simple structure, convenient accommodation ete. |
