Synopsis

《学习领域6：发动机管理系统的诊断与维修》以发动机管理系统的诊断与维修为主要内容，用车间工作任务的形式导入，以学生掌握实用的发动机管理系统的诊断与维修知识与技能为目标，用大量图片结合文字叙述，介绍发动机管理系统的诊断与维修技能及相关知识。主要内容包括汽油发动机基础知识、柴油发动机基础知识、汽油发动机管理系统的组成与检修、柴油发动机管理系统的组成与检修知识。《学习领域6：发动机管理系统的诊断与维修》适应职业院校汽车运用与维修专业实施双元制教学的师生和社会在职培训人员使用。①任务。喷油始点和喷油量用电子控制的喷油器调整，它替代了普通喷油系统中的喷油嘴和喷油器总成。与直喷式柴油机中的喷油器相似，喷油器用卡夹装在汽缸盖中。共轨喷油器在直喷式柴油机中的安装不需要汽缸盖在结构上有很大改变。②结构。喷油器由孔式喷油嘴、液压伺服系统、电磁阀组件构成。燃油从高压接头经进油通道送往喷油器，并经过进油节流孔进入阀控制室，而阀控制室经由电磁阀控制的回油节流孔与回油孔相通。出油节流孔在关闭状态时，作用在阀控制活塞上的液压力大于作用在喷油嘴针阀承压面上的力，喷油嘴针阀被压在其座面上，紧紧关闭通往喷油孔的高压通道，因而没有燃油喷人燃烧室。电磁阀动作时，打开回油节流孔，阀控制室内的压力下降，只要作用在阀控制活塞上的液压力小于作用在喷油嘴针阀承压面上的力，喷油嘴针阀立即打开，燃油经过喷孔喷入燃烧室（见图18-12）。汽油机基础知识部分：工作任务1发动机可燃混合气浓度与工况关系的学习工作任务2电控发动机可燃混合气形成装置组成的学习工作任务3可燃混合气燃烧过程的学习柴油机基础知识部分：工作任务4传统柴油机可燃混合气形成装置组成的学习工作任务5电控柴油机可燃混合气形成装置组成的学习工作任务6柴油机可燃混合气燃烧过程的学习工作任务7传统柴油机燃油喷射系统故障的诊断与维修汽油发动机管理系统的组成与检修知识部分：工作任务8发动机电控系统的组成与检修工作任务9自诊断系统工作原理的学习工作任务10点火系统的组成与检修工作任务11进气系统的组成与检修工作任务12燃油供给系统的组成与检修工作任务13排放控制系统的组成与检修工作任务14节气门控制系统的组成与检修工作任务15怠速控制系统的组成与检修工作任务16定速巡航系统（CCS）的组成与检修工作任务17自适应系统工作原理的学习柴油发动机管理系统的组成与相关知识部分：工作任务18柴油机共轨系统组成与工作原理的学习工作任务19柴油机泵喷嘴系统组成与工作原理的学习参考文献
