Stopping the Engine

Usage:

3126B 1AJ


注意

发动机带负荷运转后立即停机会引起过热并加快发动机零部件的磨损。

如果发动机已在高速和/或大负荷下持续运转过,使发动机停机之前,至少在低怠速运转发动机3分钟以降低和稳定发动机内部温度。

避免发动机热态停机可增加涡轮增压器轴和轴承的寿命。


停止在低负荷运转的发动机之前,先以怠速运转发动机30秒钟。 如果发动机以公路车速和/或以高负荷运转,停机前在怠速至少运转3分钟。 此步骤将导致降低和稳定发动机内部温度。

确保已了解了发动机的停机步骤。 按照车辆上停机系统时发动机停机,或参考车辆的原始设备制造商(OEM)提供的说明书。

  • 为停止发动机,把钥匙开关转到停机(OFF)位置。

发动机停机后

  • 检查发动机曲 轴箱油位。 保持油位在机油尺的"加(ADD)"标记和"满(FULL)"标记之间。

  • 如有必要,进行小的调整。 修理每一处渗漏并拧紧任何松动的螺栓。

  • 记下工时表的读数。 按本操作和保养手册, "保养部分的保养周期表"所述进行保养。

  • 加满燃油箱以便于防止油箱中积聚湿气。 燃油箱不要加油过满。


注意

只使用操作和保养手册冷却液规格中建议使用的防冻剂/冷却液混合液。 不这样做会造成发动机损坏。


  • 让发动机冷却下来。 检查冷却液液位。 保持冷却系统液位在加注管底部以下 13毫米(mm) (0.5英寸(inch))之内。

  • 如果预料到结冻温度,要检查冷却液的防冻保护是否正确。 必须保护冷却系统,以防其在预计的最低外部温度下结冻。 如果必要,添加合适的冷却液/水混合液。

  • 对所有被传动的设备进行必需的定期保养。 此保养会在原始设备制造商(OEM)的使用说明书中述及。
