  叉车修理浅谈叉车发动机冒烟反常的原因 1•●、排气冒黑烟:

  Brief Discussion on Forklift Truck Repair Reasons for Abnormal Smoke Emission from Forklift Engine 1. Black Smoke Emission from Forklift Truck Exhaust:
 。1) 柴油机负荷超过规则 降低负荷使之在规则的规模内
  (1) Diesel Engine Load Over Rule Load Reduction to Rule Scale
 。2) 各缸供油量不均匀 调整喷油泵
  (2) Non-uniform adjustment of fuel supply for each cylinder
 。3)气门空隙不正确•●、气门密封不良,导致气门漏气,焚烧恶化 调整气门空隙,检查密封锥面,并消除缺点
  Incorrect valve clearance and poor valve seal result in valve leakage, worsening incineration, adjusting valve clearance, checking sealing cone surface and eliminating shortcomings.
 。4) 喷油提前角太小,喷油太迟使部分燃油在排气管中焚烧
  (4) The injection advance angle is too small and the injection time is too late to burn part of the fuel in the exhaust pipe.
  调整喷油提前角
  Adjusting injection advance angle
 。5) 进气量不足:空气滤清器或进气管堵塞,涡轮增压器压气机壳过脏 清洗和铲除尘土污物,必要时替换滤芯
  (5) Intake insufficient: air filter or intake pipe blockage, turbocharger compressor shell cleaning and dust removal, if necessary, replace the filter element
 。6)涡轮增压器弹力气封环烧损或磨损,涡轮各结合面漏气等 检查或替换气封环;拧紧结合面螺钉.
  Inspect or replace the elastic air seal rings of turbochargers, such as burning or wearing, leakage of the turbine joint surface, and tighten the joint screw.
  2•●、 排气帽白烟
  2. Exhaust Cap White Smoke
 。1) 喷油器喷油雾化不良,有滴油现象,喷油压力过低 检查油嘴偶件,进行修磨或替换。重调喷油压力至规则规模。
  (1) Injector fuel atomization is not good, there is dropping phenomenon, injection pressure is too low to check the nozzle coupling, for grinding or replacement. Re-adjust injection pressure to regular scale.
 。2) 柴油机刚启动时,单个气缸内不焚烧(特别是冬天) 恰当进步转速及负荷,多工作一些时间。
  (2) When a diesel engine is just started, it will not burn in a single cylinder (especially in winter), properly improve the speed and load, and work more time.

  3•●、 排气冒蓝烟:
  3. Blue smoke from exhaust:
 。1) 空气滤清器堵塞,进气不畅或其机油盘内机油过多(油浴式空滤器)
  (1) Blocked air filter, poor air intake or excessive oil in oil pan (oil bath air filter)
  拆检和清理空气滤清器,削减机油至规则平面
  Remove and clean air filters, reduce oil to regular level
 。2) 活塞环卡住或磨损过多,弹性不足,安装时活塞环倒角方向装反,使机油进入焚烧室
  (2) The piston ring is stuck or worn too much, and its elasticity is insufficient. When installed, the piston ring is reversed in the chamfering direction, so that the oil enters the incineration chamber.
  拆检活塞环,必要时替换
  Remove and replace piston rings if necessary
 。3) 长时间低负荷(标定功率的40%以下)工作,活塞与缸套之间空隙较大,使机油易窜入焚烧室
  (3) Long time and low load (less than 40% of the calibrated power) work, and large gap between piston and cylinder liner, which makes oil easy to enter the incineration chamber.
  恰当进步负荷;配套时选用功率要恰当
  Appropriate progressive load; appropriate selection of power when matching
 。4) 油底壳内机油加入过多 按机油标尺刻线加注机油。
  (4) Too much oil is added into the oil pan to add oil according to the oil scale.
  4•●、 排气中有水分凝结现象:气缸盖裂缝,使冷却液进入气缸 替换气缸盖。
  4. There is water condensation in the exhaust: cracks in the cylinder head cause the coolant to enter the cylinder to replace the cylinder head.
