Cold Start Strategy
这些发动机使用限制功率的冷起动策略,直到冷却液温度达到 28 °C (82 °F) 。 该冷起动策略称为冷态模式。 电子系统将自动使C11和 C13发动机以800 RPM怠速运转。 电子系统将使 C15发动机以600 RPM怠速运转。 冷态模式也将改变燃油喷油量、最大起动性能正时和白烟控制正时。 冷态模式将使排放降低和减少暖机所需时间。 如果踩下了油门、行车制动或离合器,冷态模式将停止工作,发动机速度将降到保持设定的低怠速转速。
发动机应在低转速和低功率需求的工况下运转,直到发动机达到正常工作温度。 发动机在低转速和低功率需求的工况下比在怠速工况下运转时将会更快地达到正常工作温度。

直到发动机脱离冷态模式后,才能移动卡车。 如果在冷态模式下操作卡车,功率将显著降低。 |
