3500 Engines with EUI Option Caterpillar


Cat Data Link

Usage:

3508B 3LS
发动机具有一个 Cat 数据链路。 数据链路用于与其它基于微处理器的装置进行通信。

数据链路可减少系统内传感器的重复安装,使得控制装置能够分享信息。 数据链路用于将有关发动机的信息与其它电子控制系统进行通信传输。 数据链路还可用于与电子维修工具接口。

被监控并可从数据链路上得到的有关发动机的信息包括以下各项(典型示例):

  • 空气滤清器阻力

  • 大气压力

  • 增压压力

  • 冷态模式状态

  • 冷却液温度

  • 曲轴箱压力

  • 诊断讯息

  • 电子控制模块(ECM)的电源电压

  • 发动机识别

  • 发动机转速(实际转速)

  • 发动机转速(理想转速)

  • 发动机系统状态

  • 发动机报警系统

  • 排气温度

  • 过滤后机油压力

  • 燃油压力

  • 空气滤清器最大阻力

  • 机油压力

  • 油门位置百分数

  • 额定燃油限制

  • 正时标定启用 / 状态

  • 总燃油消耗量

  • 涡轮增压器进气压力

  • 涡轮增压器出气压力

将电子维修工具插入数据链路接头以和 ECM 通信。 通信适配器串联安装在电子维修工具和数据链路接头之间。 通信适配器转换由数据链路语言构成的数据。 该语言转换为电子维修工具使用的语言。 数据链路接头位于发动机线束上。 电子维修工具还可用于显示有关实时监控发动机作业的所有信息的数值。
