攪拌機的發動機是攪拌機動力輸出的關鍵，也與油耗密切相關。因此，對攪拌機發動機及其附件系統進行定期清潔和保養也可以降低油耗。想要省油，必須掌握攪拌機發動機保養關鍵規則，下面來看看吧。

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.

清潔空氣過濾器

Clean air filter

空氣濾清器在攪拌機行駛過程中直接關系到發動機的進氣量。攪拌機只在城市行駛，空氣濾清器不會堵塞，但如果攪拌機在塵土飛揚的道路上行駛后，需要特別注意清洗空氣過濾器。如果空氣濾清器堵塞或灰塵過多，都會造成攪拌機發動機進氣不良，大量灰塵進入氣缸，加快氣缸內積碳速度，造成混凝土攪拌機發動機點火不良，動力不足，攪拌機。油耗自然會增加。

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駛，攪拌機行駛5000時應檢查空氣濾清器。如果過濾器上的灰塵過多，可以考慮從濾芯內部吹出壓縮空氣將灰塵吹出網。但壓縮空氣的壓力不宜過高，以免損壞濾紙。他告訴記者，清洗空氣濾清器時一定不能用水或油，以免油和水污染濾芯。

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.

去除節流油泥

Remove throttling sludge

節流閥處產生油泥的原因有很多，其中一些是燃料燃燒的廢氣在節流閥處形成積碳；以及節流閥處空氣濾清器未過濾的雜質殘留形成。油泥過多會造成空氣阻力，從而導致油耗增加。攪拌機行駛一萬到兩萬，一般要清洗節流閥。

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.

清洗節氣門時，先拆下進氣喉，露出節氣門，拆下蓄電池負極，關閉點火開關，拉直節氣門襟翼，向節氣門內噴少量“化油器清潔劑”，然后用滌綸抹布或高紡“無紡布”仔細擦洗。在節氣門深處，您可以使用夾子夾住抹布并仔細擦洗。清洗干凈后，安裝進氣管和電池負極，就可以點擊了！

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!

清潔噴油器積碳

Clean the fuel injector carbon deposit

因為燃燒室容易積碳，積碳會造成啟動困難；噴油器積碳還會造成油路堵塞，噴油變形，霧化不良，油耗自然會增加。對于攪拌機燃燒室的清洗，可以使用專用脫碳劑將燃燒室和噴油嘴上的焦炭軟化，使其與零件表面分離，然后將軟化的焦炭去除。這種除碳方法效果好，與以往的直接擦拭相比，具有不損傷零件表面的優點，混凝土攪拌機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.
