濟南奔馳汽車保養(yǎng)之發(fā)動機的檢查項目

來源:http://m.nhakhoathuduc.net/ 日期:2022-04-05 發(fā)布人:admin
  濟南奔馳汽車的發(fā)動機由五大系統(tǒng)構(gòu)成,即冷卻系、燃油系、潤滑系、點火系和起動系,當(dāng)這五大系統(tǒng)和電腦程序工作均正常時,發(fā)動機便沒有無法起動的理由,所以發(fā)動機檢查還要從這五大系統(tǒng)入手。
  Ji 'nan Benz engine consists of five systems, that is, cooling system, fuel system, lubrication system, ignition system and starting system, when the five systems and computer programs work normally, the engine will not be able to start the reason, so the engine inspection should start from the five systems.
  冷卻系
  The cooling system
  檢查冷卻系時的需放在防凍液上,一方面要查看防凍液液位是否明顯不足,如有類似情況,需排查冷卻系統(tǒng)是否存在滲漏。
  When checking the cooling system, the center of gravity should be placed on the antifreeze. On the one hand, it is necessary to check whether the antifreeze liquid level is obviously insufficient. If there is a similar situation, it is necessary to check whether there is leakage in the cooling system.
  另外一方面,需要用儀器測量防凍液的化學(xué)狀態(tài),我們常見的防凍液檢測就是測試冰點,實際這樣的檢查并不能完全看出防凍液的好壞,相比之下,防凍液的pH值是容易被忽視的。
  On the other hand, the need to use instruments to measure the chemical state of antifreeze, our common antifreeze detection is to test the freezing point, the actual inspection can not fully see the quality of antifreeze, by contrast, the pH value of antifreeze is easy to be ignored.
  點火系
  The ignition system
  點火系主要由點火線圈和火花塞構(gòu)成,檢查時可通過點火線圈的外觀狀態(tài)進行評估,特別是對包裹火花塞絕緣柱的密封圈進行檢查,一旦密封圈老化,會出現(xiàn)漏電的不良現(xiàn)象,導(dǎo)致點火能力差。
  Ignition system is mainly composed of ignition coil and spark plug, inspection can be evaluated by the appearance of the ignition coil, especially the sealing ring of the spark plug insulation column inspection, once the sealing ring aging, there will be a bad phenomenon of leakage, resulting in poor ignition ability.
  濟南奔馳汽車保養(yǎng)認(rèn)為雖然火花塞是點火系中的重要元件,但它也能反映出燃油供給系統(tǒng)的狀態(tài)。這是因為火花塞螺口以下的部分位于燃燒室內(nèi),如果燃油過多,火花塞頭會附著黑色的積碳。
  Ji 'nan Benz automotive maintenance that although the spark plug is an important component in the ignition system, but it can also reflect the state of the fuel supply system. This is because the part below the spark plug screw is located in the combustion chamber. If there is too much fuel, the spark plug head can be attached to the black carbon deposit.
  起動系
  The starting system
  發(fā)動機和變速箱油液會隨著氣溫的降低變得粘稠,在發(fā)動機起動的瞬間,負(fù)荷會明顯增加。其中,起動機和電瓶的負(fù)擔(dān)會尤為凸顯。起動機會在運轉(zhuǎn)的瞬間產(chǎn)生強大的低扭,以帶動發(fā)動機齒盤,由于瞬間電流極大,故而長時間起動可能會造成起動機控制機構(gòu)的觸點燒蝕,影響起動時間。
  The engine and transmission oil will become thick with the decrease of temperature, and the load will increase significantly at the moment the engine starts. Among them, starter and battery burden will be particularly prominent. The starter will produce a strong low twist at the moment of operation to drive the engine gear plate. Due to the great instantaneous current, a long time starting may cause the contact ablation of the starter control mechanism, affecting the starting time.
  由于起動電流相當(dāng)大,所以起動機使用的電線是全車更粗的,足夠的線徑可以保障電路的穩(wěn)定,同時還要確保接頭通電流暢。對于連接車身的搭鐵點,技師也會逐一檢查,對于生銹的搭鐵點,會用除銹劑甚至打磨的方式處理。
  Because the starting current is quite large, so the starter uses the thickest wire of the whole car, enough wire diameter can ensure the stability of the circuit, but also to ensure that the connector is energized smoothly. For connecting the body of the iron point, the technician will check one by one, for the rust of the iron point, will use rust remover and even the way of grinding.
  另外,在檢查前,技師會先對機艙進行簡單除塵,并鋪設(shè)翼子板布,目的無需贅述--減小塵土對檢查的影響,同時防止技師在維檢的過程中誤傷車輛外觀件。更多內(nèi)容可以通過點擊網(wǎng)址m.nhakhoathuduc.net來我們網(wǎng)站進行咨詢吧。
  In addition, before the inspection, the technician will first carry out simple dust removal on the engine room, and lay the wing board cloth, the purpose is needless to say -- reduce the impact of dust on the inspection, and prevent the technician from accidentally injuring the vehicle appearance in the process of maintenance.
