    汽车发动机爆缸是什么原因?
    2020-5-26 16:20:29

      对于开车的朋友们来说,汽车的各种故障总是让人糟心的,比如汽车发动机爆缸这一情况,就非常让人头疼了,那么汽车发动机爆缸是什么原因呢,汽车发动机爆缸怎么处理呢,下面就一起来看看吧。
      For the driving friends, all kinds of car faults are always annoying. For example, the case of a car engine cylinder bursting is a headache. What's the reason for the engine cylinder bursting? How to deal with the engine cylinder bursting? Let's take a look at it together.
      汽车发动机爆缸是什么原因
      What's the reason for the cylinder bursting of automobile engine
      什么是发动机爆缸
      What is engine knock
      由于温度过高,活塞膨胀而卡在了气缸中,造成引擎报废。严重时由于压力过大而活塞又无法活动,则会喷出浓浓火焰,这就是我们常说的发动机爆缸。
      Because the temperature is too high, the piston expands and gets stuck in the cylinder, causing the engine to be scrapped. In serious cases, if the piston fails to move due to excessive pressure, a thick flame will be emitted, which is often referred to as engine cylinder blowout.
      发动机的燃烧十分复杂,所以需要有相当准确的设计与控制,稍有一点控制失误或是失常,便会造成不正常燃烧,而“爆缸”就是一种不正常燃烧。简单的说,爆缸是不正常燃烧所导致的燃烧室内压力失常。
      The combustion of the engine is very complex, so it needs to have quite accurate design and control. If there is a little control error or abnormality, it will cause abnormal combustion, and "cylinder blowout" is a kind of abnormal combustion. In short, cylinder blowout is the abnormal pressure in combustion chamber caused by abnormal combustion.
      发动机爆缸的原因
      Causes of engine cylinder blowout
      1、设计上缺陷
      1. Defects in design
      其实之所以出现汽车爆缸的主要原因还是汽车质量的问题,是汽车设计的缺陷问题,使得发动机的温度超过了发动机能承受的高温度,而造成发动机爆缸。
      In fact, the main reason for the cylinder blowout is the quality of the car. It is the defect of the car design, which makes the engine temperature exceed the maximum temperature that the engine can bear, resulting in the cylinder blowout of the engine.
      2、机油的质量和运转情况
      2. Oil quality and operation
      造成发动机爆缸除了汽车设计上的缺陷外,还与汽车机油的质量和运转情况有关系。发动机内的机油的质量不佳或者是机油的运转不良造成润滑不足,导致散热出现严重的问题,这也会引起发动机爆缸。
      In addition to the defects in automobile design, the engine cylinder blowout is also related to the quality and operation of automobile oil. The poor quality of the engine oil or the poor operation of the engine oil causes insufficient lubrication, which leads to serious problems of heat dissipation, which will also cause engine cylinder blowout.
      3、发动机进排气系统以及点火正时的调整不准确
      3. Inaccurate adjustment of engine intake and exhaust system and ignition timing
      发动机的进排气系统与点火时间的调整不准确造成时间上出现错误,也是造成发动机爆缸的一个原因。
      The inaccurate adjustment of the intake and exhaust system and the ignition time of the engine results in the error of the time, which is also one of the reasons for the engine cylinder blowout.
      4、发动机负荷过高
      4. Engine load too high
      还有一个原因就是由于对发动机的过度使用造成的。过度使用导致发动机工作负荷过高都会造成所谓爆缸或是缩缸的现象发生。

     
      Another reason is due to the excessive use of the engine. Excessive use of the engine will cause the so-called cylinder blowout or cylinder contraction.
      发动机爆缸怎么处理
      How to deal with engine cylinder bursting
      1、保发动机处于冷却状态并熄火,取下散热器盖确保发动机是凉的。
      1. Keep the engine cool and turn off. Remove the radiator cap to make sure the engine is cool.
      2、让冷却液流入桶里。
      2. Let the coolant flow into the barrel.
      3、关上排放塞(或装上水管)并给散热器注水。
      3. Close the drain plug (or install the water pipe) and fill the radiator with water.
      4、打开发动机,打开加热器控制系统,添加冷却系统清洁剂,空转发动机30分钟。
      4. Turn on the engine, turn on the heater control system, add the cooling system cleaner, and idle the engine for 30 minutes.
      5、关掉发动机冷却5分钟,将散热器内液体排空。
      5. Turn off the engine and cool down for 5 minutes, and drain the liquid in the radiator.
      6、关上排放塞,往散热器注水并让发动机空转5分钟。
      6. Close the drain plug, fill the radiator with water and allow the engine to idle for 5 minutes.
      7、重新注入50/50水和乙二醇防冻剂/冷却液的化合物。
      7. Refill with 50 / 50 water and glycol antifreeze / coolant compound.
      发动机爆缸、拉缸、缩缸的区别
      The difference of engine cylinder bursting, cylinder pulling and cylinder shrinking
      拉缸:由于活塞质量不过关,或运转时温度过高,造成活塞发生形变与汽缸壁摩擦,使汽缸壁产生划痕,造成封闭不严,动力损失。严重时会喷出青蓝色的烟。
      Cylinder pulling: because the quality of the piston is not qualified or the temperature is too high during operation, the piston deforms and rubs against the cylinder wall, causing scratches on the cylinder wall, resulting in loose sealing and power loss. When it is serious, blue smoke will be emitted.
      爆缸和缩缸这应该是同一件事情但是说法不一样,只不过爆缸这两个字听起来好象比较严重的样子,引擎会发生这种状况其实不一定是在赛车上面才会发生,在一般我们使用的市售车款如果引擎保养不好的话也会有这种惨剧会发生的,
      It should be the same thing, but it's not the same. It's just that the word "cylinder blowout" sounds like a serious thing. The engine will happen. In fact, it doesn't have to happen on the racing car. In general, if the engine maintenance is not good, this kind of tragedy will happen,
      而这种现象在赛车运动当中高度压榨引擎的状态之下,就可以说是司空见惯经常会发生的事情啦,而会发生这样的意外状况通常是在几种现象之下才会产生。
      But this kind of phenomenon can be said to be a common and frequent occurrence under the condition of highly squeezing engine in racing, and this kind of unexpected situation usually occurs under several kinds of phenomena.
