是什么原因造成了奔驰发动机的异常噪音

来源:http://www.tubeprice.net发布时间:2019-07-04 16:43:52

  阀座异常噪声现在在道路上行驶的汽车,液压缸滚子摇臂、液压缸摇臂、摇臂无论哪一个都会经常遇到发动机的“咔哒”声。发动机空转得越高,噪音也就越大。在中速以上,声音变得模糊和嘈杂。
  The abnormal noise of the valve seat is now on the road in automobiles, hydraulic cylinder roller rocker arm, hydraulic cylinder rocker arm, rocker arm no matter which one will often encounter the "click" sound of the engine. The higher the engine idles, the greater the noise. Above medium speed, the sound becomes blurred and noisy.
  一般有以下几个原因:
  There are generally the following reasons:
  (1)阀杆端部与调节螺丝或摇臂磨损或调节不当,使阀间隙过大,导致摇臂头与阀头的顶置阀和阀端碰撞;
  (1) Abrasion or improper adjustment of the stem end and the adjusting screw or rocker arm results in excessive valve clearance, which causes the rocker head to collide with the top valve and valve end of the valve head;

  5. 液压升降机或液压缸损坏。
  5. Damage of hydraulic elevator or cylinder.
  除了上述原因与油,润滑的重要条件之一,发动机润滑系统的正常工作可以实现润滑冷却密封和锈清洗,配合间隙时,温度、负载、速度是常数,润滑油膜厚度影响润滑系统压力和润滑油的质量,优质的润滑油和适当的可以产生良好的润滑油膜压力,油膜越厚,机械冲击越小,很少发生声音。如果润滑油膜过薄,导致磨损力增大,异常声音明显,清晰。
  In addition to the above reasons and oil, one of the important conditions of lubrication, the normal operation of engine lubrication system can achieve lubrication, cooling, sealing and rust cleaning. When matching clearance, temperature, load and speed are constant. The thickness of lubrication film affects the pressure of lubrication system and the quality of lubrication oil. High-quality lubrication oil and appropriate lubrication oil can produce good results. The thicker the oil film is, the smaller the mechanical impact is and the less sound is produced. If the lubricant film is too thin, the wear force will increase, and the abnormal sound will be obvious and clear.
