1、 Add as much lubricating oil as you can

小型自上料混凝土搅拌罐车润滑油量应该控制在机油尺的上、下刻度线之间为好。因为小型搅拌车润滑油过多就会从气缸与活塞的间隙中窜入燃烧室燃烧形成积炭。这些积炭会提高小型搅拌车发动机压缩比，增加产生爆震的倾向；积炭在汽缸内呈红热状态还容易引起早燃，如落入小型自上料混凝土搅拌罐车汽缸会加剧汽缸和活塞的磨损，还会加速污染润滑油。其次，小型搅拌车润滑油过多增加了曲轴连杆的搅拌阻力，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.

经常检查小型自上料混凝土搅拌罐车润滑油是正确的，但只补充不更换只能弥补机油数量上的不足，却无法完全补偿润滑油性能的损失

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、什么时候搅拌车润滑油变黑了就该换油了

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

这种理解并不到位。对于没有加清静分散剂的润滑油来说，颜色变黑的确是油品已严重变质的表现，但小型自上料混凝土搅拌罐车使用的润滑油一般都加有清静分解剂。这种清静剂将粘附在活塞上的胶膜和黑色积炭洗涤下来，并分散在油中，减少小型搅拌车发动机高温沉淀物的生成，故润滑油使用一段时间后颜色容易变黑，但这时的油品并未完全变质。

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、搅拌车润滑油经常添不用换

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

经常检查小型自上料混凝土搅拌罐车润滑油是正确的，但只补充不更换只能弥补机油数量上的不足，却无法完全补偿润滑油性能的损失。小型搅拌车润滑油在使用过程中，由于污染、氧化等原因质量会逐渐下降，同时还会有一些消耗，使数量减少。

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.

真正优良的小小型自上料混凝土搅拌罐车润滑油是具备多种发动机保护功能的成品，配方中已含有多种添加剂

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、添加剂用处大

4、 Additives are of great use

真正优良的小小型自上料混凝土搅拌罐车润滑油是具备多种发动机保护功能的成品，配方中已含有多种添加剂，其中包括抗磨剂，而且小型搅拌车润滑油讲究配方的均衡以保障各种性能的充分发挥。自行添加其他添加剂不仅不能给小型搅拌车带来额外保护，反而易与机油中的化学物质发生反应。

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.
