3.4 微机控制式点火系普通电子点火系虽然在提高点火能量和点火性能方面大大优于传统点火系,但无论是辅助触点式还是无触点式,它们对点火提前角的调节,仍与传统点火系一样,靠离心式和真空膜片式两套机械调节装置来完成。因此,存在着点火正时特性差的缺陷。微机控制式点火系废除了机械式点火提前调节装置,通过电子点火提前(Electronic Spark Advance 简称 ESA)系统
3.4 Microcomputer-controlled ignition system Although the common electronic ignition system to improve the ignition energy and ignition performance is much better than the traditional ignition system, but whether it is auxiliary contact or non-contact type, their ignition advance angle adjustment, still with the traditional Like the ignition system, by centrifugal and vacuum diaphragm two sets of mechanical adjustment device to complete. Therefore, there is a drawback that the ignition timing characteristics are poor. Computer-controlled ignition system abolished mechanical ignition advance adjustment device, by electronic ignition advance (Electronic Spark Advance referred to as ESA) system
