C15 and C18 Engines for Caterpillar Built Machines Caterpillar


Elevated Idle

Usage:

657G A4G

可能原因

这种情况不能说明存在电气系统故障。 可能会因下述特性之一而提升低怠速转速:

  • 低蓄电池电压提升怠速 (Low Battery Voltage Elevated Idle)

  • 空档滑行提升发动机转速 (Neutral Coast Elevated Engine Speed)

注: 如果启用了上述特性之一,卡特彼勒电子技师 (ET) 会显示"提升怠速 (Elevated Idle)"的状态。

条件

低蓄电池电压提升怠速 (Low Battery Voltage Elevated Idle)

如果下列所有情况出现,会将发动机怠速转速提升至 1000 rpm。

  • 已将该参数设定在"启用 (Enabled)"上。

  • 系统蓄电池电压保持 24.5 VDC 以下五分钟。

  • 油门踏板位置保持 25% 以下五分钟。

  • 机器没有挂入档位。

  • 已设置停车制动器。

空档滑行提升发动机转速 (Neutral Coast Elevated Engine Speed)

如果下列所有情况出现,会将发动机怠速转速提升至 1300 rpm。

  • 机器在空档。

  • 机器行驶速度高于 12 mph。
