柴油机在正常操作的情况下,转速失去控制,超过额定转速,即出现了“飞车”故障。这时发动机发出轰鸣声,排气管大量冒黑烟或蓝烟。“飞车”不仅造成零部件损坏,而且危及人身安全。一、发生“飞车”的原因引起“飞车”的原因,一是燃油超供,二是窜烧机油。两种“飞车”虽然都表现为超速运转,但具体现象有差别。柴油超供引起“飞车”时,排气冒黑烟,一般用切断供油的方法来制止,烧机油引起的“飞车”,排气冒蓝 Diesel engine in normal operation, the speed control, more than the rated speed, that appeared a “Speed” fault. At this time the engine roar, a large number of exhaust pipe black smoke or blue smoke. “Speed” not only caused parts damage, but also endanger personal safety. First, the occurrence of “Speed” Cause “Speed” reasons, one super-supply of fuel, and second, channeling burning oil. Although both types of “speeding car” are characterized by speeding operation, the specific phenomena are different. Diesel over for the cause of “Speed”, the exhaust black smoke, the general cut off the oil supply method to stop burning oil caused by the “Speed”, venting blue
