1、 Add as much lubricating oil as you can

小型自上料混凝土攪拌罐車潤滑油量應該控制在機油尺的上、下刻度線之間為好。因為小型攪拌車潤滑油過多就會從氣缸與活塞的間隙中竄入燃燒室燃燒形成積炭。這些積炭會提高小型攪拌車發動機壓縮比，增加產生爆震的傾向；積炭在汽缸內呈紅熱狀態還容易引起早燃，如落入小型自上料混凝土攪拌罐車汽缸會加劇汽缸和活塞的磨損，還會加速污染潤滑油。其次，小型攪拌車潤滑油過多增加了曲軸連桿的攪拌阻力，使燃油消耗增大。

The lubricating oil quantity of small concrete mixer truck should be controlled between the upper and lower scales of oil dipstick. Because the small mixer too much lubricating oil will rush into the combustion chamber from the gap between the cylinder and the piston to form carbon deposit. These carbon deposits will increase the compression ratio of small-scale mixer engine and increase the tendency to produce knock; the carbon deposit is red hot in the cylinder, and it is easy to cause early combustion. If it falls into the cylinder of small concrete mixer, it will aggravate the wear of cylinder and piston, and accelerate the pollution of lubricating oil. Secondly, the excessive lubricating oil of the small mixer increases the mixing resistance of the crankshaft connecting rod and increases the fuel consumption.

經常檢查小型自上料混凝土攪拌罐車潤滑油是正確的，但只補充不更換只能彌補機油數量上的不足，卻無法完全補償潤滑油性能的損失

It is correct to check the lubricating oil of small concrete mixer frequently, but it can only make up for the shortage of oil quantity, but can not completely compensate the loss of lubricating oil performance

二、什么時候攪拌車潤滑油變黑了就該換油了

2、 When the blender oil turns black, it's time to change the oil

這種理解并不到位。對于沒有加清靜分散劑的潤滑油來說，顏色變黑的確是油品已嚴重變質的表現，但小型自上料混凝土攪拌罐車使用的潤滑油一般都加有清靜分解劑。這種清靜劑將粘附在活塞上的膠膜和黑色積炭洗滌下來，并分散在油中，減少小型攪拌車發動機高溫沉淀物的生成，故潤滑油使用一段時間后顏色容易變黑，但這時的油品并未完全變質。

This understanding is not in place. For the lubricating oil without detergent dispersant, it is indeed a sign that the oil has deteriorated seriously. However, the lubricating oil used in small concrete mixer truck is generally added with detergent. This kind of detergent washes the adhesive film and black carbon deposits on the piston and disperses them in the oil, thus reducing the formation of high-temperature deposits in the engine of small-scale mixer. Therefore, the color of lubricating oil tends to turn black after using for a period of time, but the oil is not completely deteriorated.

三、攪拌車潤滑油經常添不用換

3、 The lubricating oil of mixer truck is often added without changing

經常檢查小型自上料混凝土攪拌罐車潤滑油是正確的，但只補充不更換只能彌補機油數量上的不足，卻無法完全補償潤滑油性能的損失。小型攪拌車潤滑油在使用過程中，由于污染、氧化等原因質量會逐漸下降，同時還會有一些消耗，使數量減少。

It is correct to check the lubricating oil of small concrete mixer frequently, but only replenishing and not changing can make up for the shortage of oil quantity, but can not completely compensate the loss of lubricating oil performance. In the process of using, the quality of lubricating oil of small mixer truck will gradually decline due to pollution and oxidation, and there will be some consumption to reduce the quantity.

真正優良的小小型自上料混凝土攪拌罐車潤滑油是具備多種發動機保護功能的成品，配方中已含有多種添加劑

The really excellent lubricating oil for small and medium-sized concrete mixer is a finished product with various engine protection functions, and the formula already contains a variety of additives

四、添加劑用處大

4、 Additives are of great use

真正優良的小小型自上料混凝土攪拌罐車潤滑油是具備多種發動機保護功能的成品，配方中已含有多種添加劑，其中包括抗磨劑，而且小型攪拌車潤滑油講究配方的均衡以保障各種性能的充分發揮。自行添加其他添加劑不僅不能給小型攪拌車帶來額外保護，反而易與機油中的化學物質發生反應。

The really excellent lubricating oil for small and medium-sized concrete mixer is a finished product with various engine protection functions. The formula already contains a variety of additives, including anti-wear agents. Moreover, the small-scale mixer lubricating oil pays attention to the balance of the formula to ensure the full play of various properties. Self adding other additives can not bring extra protection to small mixer, but easily react with chemical substances in engine oil.
