    細微液滴狀態的汽車機油和水哪里來?

    來源:http://www.philiprobert.com發布時間:2022-04-24 20:25:04

      在進行汽車維修的時候,機油方面是必不可少要進行檢查的一項,有時候會發現機油乳化,但乳化過程需要有水和機油進行混合,那么細微液滴狀態的汽車機油和水哪里來?
      When carrying out car maintenance, oil is essential to check, sometimes it can be found that oil emulsification, but the emulsification process needs to be mixed with water and oil, so where does the car oil and water in the state of fine droplets come from?
      在發動機運轉過程中所產生的熱會致使潤滑系統中的機油會出現一定程度的蒸發,借助曲軸箱通風系統,潤滑系統中的那些極其細微的機油油滴可以順著通氣腔穿過缸體、缸蓋進入氣門室。到這個階段就已經具備了機油乳化的大部分條件,接下來是水的來源以及混合過程。
      The heat generated in the process of engine operation will cause the oil in the lubrication system to evaporate to a certain extent. With the help of the crankcase ventilation system, the oil droplets in the lubrication system can be extremely fine along the ventilation chamber through the cylinder block, the cylinder head into the valve chamber. At this stage most of the conditions for oil emulsification are in place, followed by the source of the water and the mixing process.
      在低溫環境下,發動機工作時,由于氣缸蓋罩蓋溫度不能很快升高,在溫差的作用下,氣缸蓋罩蓋內易出現水凝結現象,其與機油油滴進行混合后,在發動機機油加注口、氣缸蓋罩蓋處便形成了乳化后的白色泡沫。
      In low temperature environment, when the engine is working, because the temperature of the cylinder head cover can not rise quickly, under the action of temperature difference, the cylinder head cover cover is easy to appear water condensation phenomenon, which is mixed with oil droplets, in the engine oil filling port, the cylinder head cover will form emulsified white foam.
      形成的白色泡沫并不會因此作罷,它還會引發新的問題,包括進一步導致機油的乳化現象以及氣缸內混合氣燃燒質量變差等。
      The formation of white foam does not stop it, and it can cause new problems, including further emulsification of the oil and poor combustion quality of the in-cylinder mixture.


      結合乳化現象,如果在內置油氣分離器部位(氣門室內)就已經形成了白色泡沫,那么,順著氣流流動的方向,在PCV閥打開后(PCV閥是曲軸箱通風系統的控制元件),白色泡沫也會隨之進入到外置油氣分離器(旋風式油氣分離器)內。
      Combined with emulsifying phenomenon, if the parts in the oil and gas separator (valve interior) has formed the white foam, then along the direction of the airflow, the PCV valve opens (PCV valve of the crankcase ventilation system control element), white foam will also go into the outer oil separator inside the cyclone (oil separator)。
      濟南大眾汽車保養人員認為,經其處理,氣體和液體分離(氣體送入氣缸燃燒,液體回流到油底殼),白色泡沫中的水也會被分離出來,按照正常的順序,機油將摻雜著水流回到油底殼并進入到潤滑系統中,機油質量因此受到影響。
      Jinan Volkswagen maintenance personnel think, after the treatment, gas and liquid separation (gas into the cylinder combustion, liquid back into the oil pan), the water in the white foam will be separated, in accordance with the order of the normal, the oil will be mixed with water flow back to the oil pan and into the lubrication system, oil quality so affected.
      以上便是相關講解了,另外,機油乳化同樣不可避免,只不過,因多方面原因,機油乳化的程度各有不同而已,所以要多去了解才行,更多內容就來網站www.philiprobert.com看看吧!
      The above is related to the explanation, in addition, oil emulsification is also inevitable, but, for many reasons, the degree of oil emulsification is different, so it is necessary to know more about it, more content to the website www.philiprobert.com to see!
