Ordinary lubricating oil products become thicker at low temperature, the fluidity is weakened, and the time to reach the lubrication parts is longer, which makes the vehicle difficult to start and the wear is increased, which is very unfavorable to the engine. When to change the engine oil of automatic concrete mixer and what type of engine oil to choose? Xiaobian reminds you of four points to pay attention to:

1. 盡量選擇冬夏通用的機(jī)油，通用機(jī)油無論溫度怎么變化，都能保持比較穩(wěn)定的潤(rùn)滑性能，對(duì)發(fā)動(dòng)機(jī)能夠起到較好的保護(hù)作用。

1. Try to choose the general engine oil in winter and summer. No matter how the temperature changes, the general engine oil can maintain a relatively stable lubrication performance, which can play a better role in protecting the engine.

2. 要根據(jù)發(fā)動(dòng)機(jī)的要求選擇潤(rùn)滑油，既不能在要求較低的發(fā)動(dòng)機(jī)適用過于較好的機(jī)油，也不能將低級(jí)的機(jī)油使用在要求較高的發(fā)動(dòng)機(jī)上，總之，發(fā)動(dòng)機(jī)的機(jī)油選擇要恰當(dāng)。

2. The lubricating oil should be selected according to the requirements of the engine. Neither too good engine oil should be applied to the engine with lower requirements, nor low-grade engine oil should be used to the engine with higher requirements. In a word, the engine oil selection should be appropriate.
               

3. 自動(dòng)混凝土攪拌車要根據(jù)發(fā)動(dòng)機(jī)的狀況來選擇，如果發(fā)動(dòng)機(jī)是新的或者狀況良好的，要盡可能選用粘度較低的機(jī)油，從而保證潤(rùn)滑油的流動(dòng)暢通無阻，有效減少啟動(dòng)時(shí)的磨損。

3. The automatic concrete mixer should be selected according to the condition of the engine. If the engine is new or in good condition, the engine oil with lower viscosity should be selected as far as possible, so as to ensure the smooth flow of lubricating oil and effectively reduce the wear during starting.

4. 如果在高溫季節(jié)或發(fā)動(dòng)機(jī)已經(jīng)磨損到一定程度，就要選用高粘度的機(jī)油，這樣才能有利于形成較厚的油膜，維持機(jī)油的壓力，并減少機(jī)油消耗。

4. If the engine has been worn to a certain extent in the high temperature season, it is necessary to choose high viscosity oil, which is conducive to the formation of a thicker oil film, maintaining the oil pressure and reducing oil consumption.

5.機(jī)油的添加量不能過多，機(jī)油添加量并不是越多越好，如果潤(rùn)滑油過多，就會(huì)增加曲軸的轉(zhuǎn)動(dòng)阻力，降低發(fā)動(dòng)機(jī)的輸出功率，并且哪些過量的機(jī)油會(huì)竄入燃燒室燃燒，造成車輛燒機(jī)油，冒藍(lán)煙，以于油耗增加。所以在添加機(jī)油的時(shí)候，一定要略低于機(jī)油尺以高刻度為宜；此外還要掌握機(jī)油的型號(hào)、換油的季節(jié)、發(fā)動(dòng)機(jī)的性能等諸多因素。

5. The amount of oil should not be too much. The more the oil is added, the better. If there is too much lubricating oil, it will increase the rotation resistance of the crankshaft and reduce the output power of the engine. What excess oil will rush into the combustion chamber and cause the vehicle to burn oil and emit blue smoke, so that the fuel consumption will increase. Therefore, when adding engine oil, it must be slightly lower than the oil dipstick, and the high scale is appropriate; in addition, it is necessary to master many factors, such as the type of engine oil, the season of oil change, the performance of the engine, etc.
