C4.4 448
正确的运转和保养是获得发动机最大寿命和经济性的关键因素。 如果按照操作和保养手册中的指示去做,使用费用可以降至最低,使用寿命可以最大限度地延长。

使发动机达到正常工作温度的所需要时间要少于对发动机进行巡回检查所需要的时间。

发动机起动并达到工作温度之后,发动机就可在额定转速下操作。 发动机在低发动机转速和低功率需求时达到正常工作温度将会快些。 此程序比发动机无负荷怠速运转的情况要更有效率。 发动机应在数分钟内达到工作温度。

避免长时间怠速运转。 过度怠速导致积碳, 发动机渗液 和 柴油微粒滤清器(DPF)烟尘负荷。 这些对发动机是有害的。

发动机运行时,应观察仪表读数,经常记录数据。 比较长期数据将有助于确定每一个仪表的正常读数。 比较长期数据也将有助于发觉非正常运行的发展变化。 应调查读数中的明显变化。

微粒排放物的减少

柴油微粒滤清器(DPF)将减少微粒排放物。 DPF 收集烟尘和发动机燃烧产生的灰分。 再生期间,烟尘转换为气体,释放到大气中。 灰分一直留在 DPF 中。

DPF 的温度必须高于一定值才能进行再生。 排气为再生过程提供热量。

被动再生 - 发动机提供再生所需的足够的排气温度。

发动机运转和 DPF

发动机正常运转期间,发动机操作员可能注意到排气系统冒出的黑烟减少。

DPF 利用被动再生过程,以便清除 DPF 的烟尘。 在某些应用中,发动机怠速将自动增大,以便让被动再生出现。
