3406E, C-10 and C-12 On-highway Engines Caterpillar


Excessive Fuel Consumption

Usage:

3406E 1LW

可能的原因

  • 车辆的操作

  • 环境条件

  • 发动机负荷及车辆空气动力学

  • 燃油质量

  • 进气或排气系统

建议采取的措施

检查车辆的操作

使用卡特彼勒 电子技师检查柱状图。 寻找下列项目

  • 发动机转速

  • 车速

发动机转速和车速过高都会造成燃油消耗过多。

检查环境条件

大风和过高的湿度(雪)对燃油消耗有负面影响。

检查负荷及空气动力学

重载和较差的空气动力学特性对燃油消耗有负面影响。

检查燃油质量

燃油的等级会影响燃油的消耗率。 更多有关资料,参见操作和保养手册。

检查近期和排气系统

检查进气系统有无阻塞和漏气。 检查排气系统有无阻塞和漏气。 参见系统操作/测试和调整, "进气和排气系统"。
