General Information
这些发动机配备电子控制系统。电子控制模块(ECM)发送信号到燃料计量阀,以控制燃料的传送。
电子控制系统由 ECM、发动机传感器和操作员接口组成。 ECM 是一个控制发动机工作的计算机。 闪存文件是此计算机的软件。 闪存文件中包含工况图。 工况图可确定发动机的以下特性:
- 功率
- 扭矩曲线
- 发动机转速(rpm)
关于电子控制系统的其他信息,请参阅故障诊断与排除, "系统概述"。
ECM 通过软件和发动机上的电气接头与操作员联系。软件可配置。这允许发动机支持多种应用。
现场提供到电气接头的输入,以表明开关状态。ECM 将处理这个输入。 ECM 调整发动机的工作,以便满足不同场所的需要。关于配置输入的其他信息,请参阅故障诊断与排除, "可编程的参数"。ECM 通过电气接头为场所提供输出,以控制灯、电磁线圈或其它设备。
