搅拌一体车润滑系正常工作时，机油不断地在一体车发动机内循环流动，对各运动摩擦表面进行强制润滑，并从各摩擦表面带走磨屑和摩擦热，由于有效地向缸壁飞溅，保证了活塞环和缸壁在高温高压下的密封性和润滑作用。你知道机油变质的原因主要有几点吗？

When the lubrication system of the agitator truck works normally, the engine oil continuously circulates in the engine of the truck, forcibly lubricates the moving friction surfaces, and takes away the wear debris and friction heat from the friction surfaces. Due to the effective splash to the cylinder wall, the sealing and lubrication of the piston ring and cylinder wall under high temperature and pressure are ensured. Do you know the main reasons for oil deterioration?

搅拌一体车发动机所装用的离心式机油滤清器和全流式纸质机油滤清器，较好地维持着机油的良好品质，但是随着车辆行驶里程的增加，一体车发动机机油滤清器的过滤能力逐渐降低，积聚在润滑油里的没有燃烧过的燃料、水、燃烧生成物(如积碳、焦炭)、润滑油的氧化生成物(胶质、沥青、各种酸等)、砂粒、灰尘、黑色及有色金属磨损的颗粒愈来愈多。

The centrifugal oil filter and full flow paper oil filter installed in the engine of the agitator integrated vehicle maintain the good quality of the engine oil. However, with the increase of the vehicle mileage, the filtering capacity of the engine oil filter of the integrated vehicle gradually decreases, and the unburned fuel, water, combustion products (such as carbon deposit and coke), oxidation products of lubricating oil (gum, asphalt, various acids, etc.) Sand, dust, black and non-ferrous metal wear particles are more and more.

沉积在燃烧室和活塞顶部的胶质，能形成积碳而引起一体车发动机不正常燃烧;活塞环、气门杆上有胶质，会使这些零件咬死粘住，加剧了一体车发动机各部件的磨损。

The gum deposited on the combustion chamber and the top of the piston can form carbon deposits and cause abnormal combustion of the integrated vehicle engine; There is gum on the piston ring and valve stem, which will cause these parts to bite and stick, and aggravate the wear of various components of the all-in-one vehicle engine.

机油变质的原因主要有以下几点:

The main reasons for oil deterioration are as follows:

①机件摩擦所产生的屑末沉积;

① Chip deposition generated by friction of parts;

②燃烧时，高温氧化产生的漆膜、沉积物胶质和积碳;

② Paint film, deposit colloid and carbon deposit produced by high-temperature oxidation during combustion;

④燃烧时生成的酸性物质;

④ Acids generated during combustion;

⑤曲轴箱通风装置阻塞，机油散热不良，机油受热自然形成胶质;

⑤ The crankcase ventilation device is blocked, the engine oil has poor heat dissipation, and the engine oil naturally forms colloid when heated;

⑥过浓混合气中未雾化的汽油混人机油;及水套中的冷却水渗人机油等。

⑥ The un atomized gasoline in the rich mixture is mixed with the engine oil; And the cooling water in the water jacket seeps into the engine oil, etc.
