小手扶拖拉机配套单缸柴油机,当喷油嘴喷油压力过低或喷油嘴针阀与针阀体卡死在开启位置时,有时也会引起“飞车”。出现此故障应重新调整喷油嘴压力。如因喷油嘴针阀与针阀体卡死在开启位置,应拆下喷油嘴偶件,把喷油嘴针阀尾杆夹在虎钳上,用铜锤轻轻敲击喷油嘴针阀体与喷油嘴体接合平面,取出喷油嘴针阀。不易取出时,先将喷油嘴放在机油内,在80～100℃的情况下煮沸0.5～1.0小时,或用机油浸泡
Small walking tractor with a single cylinder diesel engine, when the fuel injection nozzle pressure is too low or injector needle and needle stuck in the open position, sometimes also cause “fly ”. In the event of this failure, the nozzle pressure should be readjusted. As a result of nozzle needle and needle stuck in the open position, should remove the nozzle coupling, the needle nozzle needle rod clamp on the vise, with a copper hammer gently tap the nozzle Needle body and nozzle body engagement plane, remove the nozzle needle. Not easy to remove, the first nozzle on the oil, at a temperature of 80 ~ 100 ℃ boil 0.5 to 1.0 hours, or soaked in oil
