1、 Hot car. It is necessary to have more patience and better habits to drive a turbocharged vehicle. After the mixer is cold started, it is not only to make the water temperature reach the normal value, but also to make the engine oil of the mixer reach the optimal working temperature. There is no need to worry about the model without oil temperature gauge. During cold start, as long as the temperature of water temperature gauge reaches the normal working temperature, wait 1-2 minutes more. Do not run at high speed immediately after starting the mixer, because turbocharging is a high-speed running part, so it needs more oil for protection. If the car is driven at high speed before it is hot, the oil is still viscous and the lubrication effect is poor. If the turbine is forced to work at full load, the turbine mill will be increased The turbine life is shortened.

二、熄火。同樣的，熄火前也需要耐心多等一等，因?yàn)殚L(zhǎng)時(shí)間行駛的攪拌車或者是高速行駛的攪拌車，渦輪增壓器的溫度都是非常高的，停車后，渦輪由于慣性還會(huì)繼續(xù)運(yùn)轉(zhuǎn)一段時(shí)間，需要足夠的時(shí)間冷卻，如果停車后就馬上關(guān)掉攪拌車發(fā)動(dòng)機(jī)，那么冷卻系統(tǒng)和潤(rùn)滑油的供應(yīng)也會(huì)停止，這樣會(huì)傷害到攪拌車的軸承。所以，建議熄火前先讓攪拌車發(fā)動(dòng)機(jī)運(yùn)轉(zhuǎn)2-3分鐘，讓渦輪增壓器有足夠的時(shí)間冷卻。但渦輪增壓器也不可長(zhǎng)時(shí)間怠速運(yùn)轉(zhuǎn)，否則攪拌車渦輪增壓器也會(huì)因機(jī)油壓力過(guò)低而導(dǎo)致潤(rùn)滑不良，一般怠速時(shí)間不應(yīng)超過(guò)10分鐘。

2、 Turn off the engine. Similarly, you need to be patient before you turn off the engine, because the temperature of the turbocharger is very high for a long time or a high-speed mixer. After parking, the turbine will continue to run for a period of time due to inertia, so it needs enough time to cool down. If you turn off the engine of the mixer immediately after stopping, then the cooling system and lubricating oil supply will be provided It will also stop, which will damage the bearing of the mixer. Therefore, it is recommended to let the engine of the mixer run for 2-3 minutes before the engine is turned off, so that the turbocharger has enough time to cool down. However, the turbocharger can not idle for a long time, otherwise the turbocharger of mixer truck will also cause poor lubrication due to low oil pressure. Generally, the idle time should not exceed 10 minutes.

三。機(jī)油。攪拌車渦輪增壓器確實(shí)比較“嬌氣”，除了機(jī)油量比普通自然吸氣發(fā)動(dòng)機(jī)大一些外，對(duì)油品的要求也更高。因?yàn)閿嚢柢嚋u輪增壓器的設(shè)計(jì)與自然吸氣發(fā)動(dòng)機(jī)不同，大部分量產(chǎn)車的渦輪都是采用浮動(dòng)軸承，即完全靠機(jī)油來(lái)潤(rùn)滑，所以，選擇優(yōu)質(zhì)的機(jī)油尤為重要，而劣質(zhì)機(jī)油的粘稠度較高，流動(dòng)性較差，無(wú)法較好地發(fā)揮作用。司機(jī)在這方面切勿因小失大，建議給攪拌車更換全合成機(jī)油，這種油品有良好的抗氧化性，抗磨性，耐高溫性能，潤(rùn)滑和散熱性更佳。

3. engine oil. The turbocharger of mixer truck is really more delicate. In addition to the larger oil quantity than the ordinary naturally aspirated engine, it also has higher requirements for oil. Because the turbocharger design of mixer truck is different from that of naturally aspirated engine, the turbine of most mass production vehicles adopts floating bearing, that is, it is completely lubricated by oil. Therefore, it is particularly important to select high-quality engine oil, while inferior oil has high viscosity and poor fluidity, so it can not play a good role. The driver should not lose a lot in this respect. It is suggested to replace the fully synthetic engine oil for the mixer. This kind of oil has good oxidation resistance, wear resistance, high temperature resistance, better lubrication and heat dissipation.

四、檢查。應(yīng)定時(shí)檢查攪拌車渦輪增壓器的密封環(huán)，因?yàn)檫@也是很重要的一個(gè)部分，因?yàn)槿绻芊猸h(huán)失效，那么廢氣會(huì)通過(guò)密封環(huán)進(jìn)入攪拌車發(fā)動(dòng)機(jī)潤(rùn)滑系統(tǒng)使機(jī)油變臟，從而使曲軸箱壓力升高，造成攪拌車機(jī)油的過(guò)度消耗,產(chǎn)生“燒機(jī)油”的情況。另外，攪拌車渦輪增壓器轉(zhuǎn)子軸承精密度很高，維修及安裝時(shí)的工作環(huán)境要求也很嚴(yán)格，因此當(dāng)渦輪增壓器出現(xiàn)故障或損壞時(shí)應(yīng)到指定的維修站進(jìn)行維修，而不能到街邊店修理。

4、 Check. The sealing ring of turbocharger of mixer truck should be checked regularly, because this is also a very important part, because if the sealing ring fails, the waste gas will enter into the engine lubrication system of the mixer through the sealing ring, which will make the oil dirty, thus increasing the pressure of the crankcase, resulting in excessive consumption of the engine oil of the mixer, resulting in "engine oil burning". In addition, the rotor bearing precision of the mixer turbocharger is very high, and the working environment requirements for maintenance and installation are also very strict. Therefore, when the turbocharger fails or is damaged, it should be repaired at the designated maintenance station instead of the street shop.
