摘要
电喷发动机上使用的闭环控制液化石油气装置从供气方式上可分为混合器式、气态喷射式和液态喷射式,液态喷射式ＬＰＧ装置也称为ＬＰＩ系统。介绍了ＬＰＩ系统的工作过程、保持液态ＬＰＧ的方法及其电子控制方式。由于采用液态喷射,与混合器式和气态喷射式ＬＰＧ系统相比,具有响应时间快、喷射精确及时及不占用空气进气体积等特点。
Loop control liquefied petroleum gas systems used in electronic control fuel injection engine applications can bedivided into mixer types, gaseous injection types and liquid injection types. Liquid injection type LPG systems are also called asLPI systems. The operating processes of LPI systems, methods to keep LPG and electronic control mode are introduced. LPIsystems have advantages of short response time, precious and on - time injection and no occupation of air volume over mixer typeand gaseous injection type LPG systems.
