攪拌車發(fā)動機(jī)燒機(jī)油的原因和檢修

自動攪拌一體車是我們生活中常見的工程車輛，車主們在使用過程重要注意保養(yǎng)周期和方式，不然的話有可能發(fā)生危險，現(xiàn)在我們就混凝土攪拌車發(fā)動機(jī)燒機(jī)油的原因來做一個簡單的闡述。

Automatic mixer is a common engineering vehicle in our life. Owners should pay attention to the maintenance cycle and mode in the use process, otherwise it may be dangerous. Now we will briefly explain the reasons for the engine oil burning of concrete mixer.

混凝土攪拌車正常行駛條件下每行駛5000對制動蹄片檢查一次，不僅要檢查剩余的厚度，還要檢查混凝土攪拌車蹄片磨損的狀態(tài)，兩邊磨損的程度是否一樣，回位是否自如等，發(fā)現(xiàn)不正常情況必須立即處理。更換時要換原廠備件提供的混凝土攪拌車剎車片，只有這樣，才能使混凝土攪拌車剎車片和剎車盤之間的制動效果好，磨損小。攪拌車制動蹄片更換后，需磨合200方能達(dá)到佳的制動效果，剛換的混凝土攪拌車蹄片須謹(jǐn)慎行駛。自動攪拌一體車發(fā)動機(jī)燒機(jī)油的原因和檢修的因素下面我們大家一起來了解一下：

Under the normal driving conditions of the concrete mixer, the brake shoe shall be inspected every 5000 km. Not only the remaining thickness, but also the wear state of the concrete mixer shoe, whether the wear degree on both sides is the same, whether it can return freely, etc. if abnormal conditions are found, they must be handled immediately. During replacement, the brake pads of the concrete mixer provided by the original spare parts shall be replaced. Only in this way can the braking effect between the brake pads and brake discs of the concrete mixer be good and the wear is small. After the brake shoe of the mixer is replaced, it needs to be run in for 200km to achieve good braking effect. The newly replaced concrete mixer shoe must be driven carefully. The causes and maintenance factors of engine oil burning of automatic mixer are as follows:

一，自動攪拌一體車混合氣在燃燒室內(nèi)燃燒，其火焰是由點(diǎn)火點(diǎn)以“波”的方式向四周擴(kuò)散，所以從點(diǎn)火到油氣完全燃燒需要一段短暫的時間。

1、 The mixture of the automatic mixing integrated vehicle burns in the combustion chamber, and its flame diffuses from the ignition point in a "wave" way, so it takes a short time from ignition to complete combustion of oil and gas.

二，油氣雖然需要靠混凝土攪拌車火花塞點(diǎn)燃，但是過于高溫、高壓的環(huán)境也會使油氣自燃。

2、 Although oil and gas need to be ignited by the spark plug of concrete mixer, too high temperature and high pressure environment will also cause oil and gas spontaneous combustion.

一般的爆震是因?yàn)槿紵覂?nèi)油氣點(diǎn)火后，火焰尚未完全擴(kuò)散，遠(yuǎn)程未燃的油氣即因?yàn)楦邷鼗蚋邏憾匀迹浠鹧媾c正規(guī)燃燒的火焰撞擊而產(chǎn)生較大壓力，使得混凝土攪拌車發(fā)動機(jī)產(chǎn)生不正常的敲擊。

The general detonation is because the flame has not fully diffused after the oil and gas in the combustion chamber is ignited. The long-distance unburned oil and gas is spontaneous combustion due to high temperature or high pressure. Its flame collides with the regular combustion flame to produce large pressure, resulting in abnormal knocking of the concrete mixer engine.

造成爆震主要有以下幾點(diǎn)原因：

Knock is mainly caused by the following reasons:

一、點(diǎn)火角過于提前：為了使活塞在壓縮上止點(diǎn)結(jié)束后，一進(jìn)入動力沖程能立即獲得動力，通常都會在活塞達(dá)到上止點(diǎn)前提前點(diǎn)火。而過于提早的點(diǎn)火會使得活塞還在壓縮行程時，大部分油氣已經(jīng)燃燒，此時未燃燒的油氣會承受較大的壓力自燃，而造成爆震。

1、 Ignition angle is too early: in order to obtain power immediately after the piston enters the power stroke after the compression TDC, it is usually ignited in advance before the piston reaches the TDC. Too early ignition will cause most of the oil and gas to burn when the piston is still in the compression stroke. At this time, the unburned oil and gas will spontaneous combustion under great pressure, resulting in detonation.

二、自動攪拌一體車發(fā)動機(jī)過度積碳：混凝土攪拌車發(fā)動機(jī)于燃燒室內(nèi)過度積碳，除了會使壓縮比增大，也會在積碳表面產(chǎn)生高溫?zé)狳c(diǎn)，使混凝土攪拌車水泥發(fā)動機(jī)爆震。

2、 Excessive carbon deposition in the engine of the automatic mixer: excessive carbon deposition in the combustion chamber of the concrete mixer engine will not only increase the compression ratio, but also produce high-temperature hot spots on the carbon deposition surface, causing the cement engine of the concrete mixer to knock.

三、空燃比不正確：過于稀的燃料空氣混合比，會使得燃燒溫度提升，而燃燒溫度提高會造成混凝土攪拌車發(fā)動機(jī)溫度提升，當(dāng)然容易爆震。

3、 Incorrect air-fuel ratio: too thin fuel air mixture ratio will increase the combustion temperature, and the increase of combustion temperature will increase the engine temperature of concrete mixer truck. Of course, it is easy to knock.

四、燃油辛烷值過低：辛烷值是燃油抗爆震的指標(biāo)，辛烷值越高，抗爆震性越強(qiáng)。壓縮比高的混凝土攪拌車發(fā)動機(jī)，燃燒室的壓力較高，若是使用抗爆震性低的燃油，則容易發(fā)生爆震。

4、 Low octane number of fuel: octane number is an indicator of fuel anti knock. The higher the octane number, the stronger the anti knock performance. The pressure in the combustion chamber of the concrete mixer engine with high compression ratio is high. If the fuel with low explosion resistance is used, it is easy to knock.

自動攪拌一體車.制動蹄片一般由鐵襯板和摩擦材料兩部分組成，一定不要等摩擦材料部分都磨沒了才更換蹄片。

The brake shoe of the automatic mixing integrated vehicle is generally composed of iron lining plate and friction materials. Do not replace the shoe until the friction materials are worn out.
