对当今高档汽车上的点火提前系统ESA向读者作以介绍.ESA系统,其主体是由电脑主板与分布在发动机各部位的传感器构成.其工作原理类似于大脑通过神经网络采集信息,然后下达指令,是一个闭环可控可测系统.为便于理解,本文不采用较专业的公式与理论,旨在分析各部件的工作原理及结构特点. Introducing the ESA to today’s high-end ignition systems, the main body of the ESA system consists of a computer motherboard and sensors located in various parts of the engine that work in a manner similar to the brain gathering information through a neural network and then issuing instructions , Is a closed-loop controllable measurable system.In order to understand, this article does not use more professional formula and theory, aims to analyze the working principle and structural characteristics of each component.
