如果使用更好的机油，则无需一直更换滤芯。一些小型搅拌机司机认为，如果你使用更好的油，它更清洁，然后你不需要定期更换滤芯。不同牌号的润滑油在使用过程中质量会发生变化。行驶一定里程后，车辆性能会恶化，可能会给发动机带来各种问题。

If better oil is used, the filter element does not need to be changed all the time. Some small mixer drivers think that if you use better oil, it will be cleaner, and then you don't need to change the filter element regularly. The quality of different grades of lubricating oil will change during use. After driving a certain mileage, the vehicle performance will deteriorate, which may bring various problems to the engine.

当机油通过机油滤清器滤芯的孔时，机油中的固体颗粒和粘性物质会积聚在滤清器中。如果滤清器堵塞，机油将无法顺利通过滤清器滤芯，从而使滤清器滤芯爆裂或打开阀并通过旁通阀，这仍会将污垢带回润滑部位，加速发动机磨损，加剧内部污染。

When the oil passes through the hole of the oil filter element, solid particles and viscous substances in the oil will accumulate in the filter. If the filter is blocked, the oil will not pass through the filter element smoothly, so that the filter element will burst or the safety valve will be opened and pass through the bypass valve, which will still bring dirt back to the lubricating part, accelerate engine wear and intensify internal pollution.

因此，定期更换机油滤芯同样重要。不要少加机油，但不要多加机油。企业合成机油越贵越好。适合你的车的机油是好的。

Therefore, it is equally important to change the oil filter element regularly. Do not add less oil, but do not add more oil. The more expensive the brand synthetic oil, the better. The oil suitable for your car is good.

空气滤清器不需要经常更换。有人认为驾驶环境中灰尘不大，所以空气滤清器可以长期更换。实际上，发动机的进气系统主要由空气滤清器和进气管组成。因此，应根据不同的使用条件定期清洗空气滤清器滤芯。一般情况下，空气滤清器滤芯应在清洗三次后更换。清洁周期可根据日常驾驶区域的空气质量确定。购买厂家提供的原厂空气滤芯也是非常重要的。

The air filter does not need to be changed frequently. Some people think that there is not much dust in the driving environment, so the air filter can be replaced for a long time. In fact, the intake system of the engine is mainly composed of air filter and intake pipe. Therefore, the air filter element should be cleaned regularly according to different service conditions. Generally, the air filter element should be replaced after three times of cleaning. The cleaning cycle can be determined according to the air quality in the daily driving area. It is also very important to purchase the original high-quality air filter element provided by the manufacturer.

不少小型搅拌机车主会认为进气管中的灰尘会被吹出。如果混凝土搅拌机经常在粉尘较多、空气质量较差的区域运行，应注意清洗进风管，保证进风顺畅。进气管对于发动机的正常运行非常重要。如果进气管太脏，效率会降低，使发动机不能在正常的输出功率范围内运转，加剧发动机的磨损和老化。尽量去灰尘较少的地区，同时，空调格栅也要注意更换。

Many small mixing locomotive owners will think that the dust in the air inlet pipe will be blown out. If the concrete mixer often operates in areas with high dust and poor air quality, pay attention to cleaning the air inlet pipe to ensure smooth air inlet. The intake manifold is very important for the normal operation of the engine. If the intake pipe is too dirty, the efficiency will be reduced, making the engine unable to operate within the normal output power range, and aggravating the wear and aging of the engine. Try to go to areas with less dust. At the same time, pay attention to replacing the air conditioning grille.
