搅拌机的发动机是搅拌机动力输出的关键，也与油耗密切相关。因此，对搅拌机发动机及其附件系统进行定期清洁和保养也可以降低油耗。想要省油，必须掌握搅拌机发动机保养关键规则，下面来看看吧。

The engine of the mixer is the key to the power output of the mixer, which is also closely related to the fuel consumption. Therefore, regular cleaning and maintenance of mixer engine and its accessory system can also reduce fuel consumption. To save fuel, you must master the key rules of mixer engine maintenance. Let's take a look.

清洁空气过滤器

Clean air filter

空气滤清器在搅拌机行驶过程中直接关系到发动机的进气量。搅拌机只在城市行驶，空气滤清器不会堵塞，但如果搅拌机在尘土飞扬的道路上行驶后，需要特别注意清洗空气过滤器。如果空气滤清器堵塞或灰尘过多，都会造成搅拌机发动机进气不良，大量灰尘进入气缸，加快气缸内积碳速度，造成混凝土搅拌机发动机点火不良，动力不足，搅拌机。油耗自然会增加。

The air filter is directly related to the air intake of the engine during the driving of the mixer. The mixer is only driven in cities, and the air filter will not be blocked. However, if the mixer is driven on dusty roads, special attention should be paid to cleaning the air filter. If the air filter is blocked or there is too much dust, the air intake of the mixer engine will be poor, and a large amount of dust will enter the cylinder, accelerating the carbon deposition in the cylinder, resulting in poor ignition of the concrete mixer engine, insufficient power and the mixer. Fuel consumption will naturally increase.

如果在正常的城市道路上行驶，搅拌机行驶5000时应检查空气滤清器。如果过滤器上的灰尘过多，可以考虑从滤芯内部吹出压缩空气将灰尘吹出网。但压缩空气的压力不宜过高，以免损坏滤纸。他告诉记者，清洗空气滤清器时一定不能用水或油，以免油和水污染滤芯。

If you drive on a normal urban road, check the air filter when the mixer runs 5000 km. If there is too much dust on the filter, consider blowing compressed air from the inside of the filter element to blow the dust out of the net. However, the pressure of compressed air should not be too high to avoid damaging the filter paper. He told reporters that water or oil must not be used to clean the air filter, so as not to pollute the filter element with oil and water.

去除节流油泥

Remove throttling sludge

节流阀处产生油泥的原因有很多，其中一些是燃料燃烧的废气在节流阀处形成积碳；以及节流阀处空气滤清器未过滤的杂质残留形成。油泥过多会造成空气阻力，从而导致油耗增加。搅拌机行驶一万到两万，一般要清洗节流阀。

There are many reasons for producing sludge at the throttle valve, some of which are carbon deposition at the throttle valve caused by the exhaust gas from fuel combustion; And the residue of unfiltered impurities in the air filter at the throttle valve. Too much sludge will cause air resistance, resulting in increased fuel consumption. Generally, the throttle valve shall be cleaned when the mixer runs for 10000 to 20000 kilometers.

清洗节气门时，先拆下进气喉，露出节气门，拆下蓄电池负极，关闭点火开关，拉直节气门襟翼，向节气门内喷少量“化油器清洁剂”，然后用涤纶抹布或高纺“无纺布”仔细擦洗。在节气门深处，您可以使用夹子夹住抹布并仔细擦洗。清洗干净后，安装进气管和电池负极，就可以点击了！

When cleaning the throttle valve, first remove the air inlet pipe to expose the throttle valve, remove the negative pole of the battery, turn off the ignition switch, straighten the throttle flap, spray a small amount of "carburetor cleaner" into the throttle valve, and then carefully wipe it with polyester cloth or high-speed "non-woven cloth". Deep in the throttle valve, you can use a clip to hold the cloth and carefully scrub it. After cleaning, install the air intake pipe and battery negative pole, and you can click!

清洁喷油器积碳

Clean the fuel injector carbon deposit

因为燃烧室容易积碳，积碳会造成启动困难；喷油器积碳还会造成油路堵塞，喷油变形，雾化不良，油耗自然会增加。对于搅拌机燃烧室的清洗，可以使用专用脱碳剂将燃烧室和喷油嘴上的焦炭软化，使其与零件表面分离，然后将软化的焦炭去除。这种除碳方法效果好，与以往的直接擦拭相比，具有不损伤零件表面的优点，混凝土搅拌机除碳效率也大大提高。

Because the combustion chamber is prone to carbon deposition, carbon deposition will cause difficulty in starting; Fuel injector carbon deposition will also cause fuel circuit blockage, fuel injection deformation, poor atomization, and fuel consumption will naturally increase. For the cleaning of mixer combustion chamber, special decarbonizing agent can be used to soften the coke on the combustion chamber and fuel injection nozzle, separate it from the surface of parts, and then remove the softened coke. Compared with the previous direct wiping, this method has the advantage of not damaging the surface of parts, and the carbon removal efficiency of concrete mixer is greatly improved.
