將超聲波清洗機引入汽車維修車間，為這些精密部件的深度清潔提供了一套高效、徹底的解決方案。

Introducing ultrasonic cleaning machines into automotive repair workshops provides an efficient and thorough solution for deep cleaning of these precision components.

燃油系統堵塞的成因與危害

Causes and hazards of fuel system blockage

化油器和噴油嘴都是精密的液壓元件，其內部通道和噴孔直徑極小，通常只有幾十到幾百微米。當車輛長時間使用后，燃油中的膠質、雜質以及燃燒室回竄的積碳會逐漸沉積在這些細小的通道內壁上。

The carburetor and fuel injector are both precision hydraulic components, with extremely small internal channels and nozzle diameters, typically only tens to hundreds of micrometers. After prolonged use of the vehicle, the gum, impurities, and carbon deposits from combustion chamber backflow in the fuel will gradually deposit on the inner walls of these small channels.

化油器：量孔和怠速油道堵塞會導致混合氣過稀，引發啟動困難、加速無力、怠速不穩。

Carburetor: blockage of the measuring hole and idle oil passage can cause the mixture to be too lean, leading to difficulty starting, weak acceleration, and unstable idle.

噴油嘴：噴孔積碳會改變噴射角度和霧化效果，導致燃油燃燒不充分，油耗增加，尾氣排放超標，嚴重時會出現缺缸抖動。

Fuel injector: Carbon buildup in the nozzle can change the injection angle and atomization effect, leading to incomplete fuel combustion, increased fuel consumption, excessive exhaust emissions, and in severe cases, cylinder misfire and shaking.

傳統清洗方式的局限

The limitations of traditional cleaning methods

對于噴油嘴，許多維修店采用“打吊瓶”的方式進行免拆清洗。這種方法雖然方便，但只能溶解掉噴油嘴表面的部分膠質，對于噴孔內部已經硬化的積碳和雜質，效果微乎其微。而對于化油器，手工拆卸后用化清劑噴洗，也很難徹底清除內部彎角處的頑固污垢。

For fuel injectors, many repair shops use the "hanging bottle" method for non disassembly cleaning. Although this method is convenient, it can only dissolve some of the gum on the surface of the fuel injector, and has little effect on the hardened carbon deposits and impurities inside the nozzle. For carburetors, it is also difficult to completely remove stubborn dirt at the internal corners by manually disassembling and spraying chemical cleaning agents.

超聲波清洗：徹底的解決方案

Ultrasonic cleaning: a thorough solution

將化油器或噴油嘴拆解下來，放入專用的超聲波清洗機中進行清洗，是目前公認的最徹底的方法。

Disassembling the carburetor or fuel injector and placing it in a specialized ultrasonic cleaning machine for cleaning is currently recognized as the most thorough method.

深度拆解：將化油器分解為上體、中體、下體，取出所有量孔、針閥等細小零件；將噴油嘴拆下，取出濾網和密封圈（如果可拆）。

Deep disassembly: Disassemble the carburetor into upper body, middle body, and lower body, and remove all small parts such as measuring holes and needle valves; Remove the fuel injector and take out the filter screen and sealing ring (if detachable).

選擇合適的清洗液：將拆解的零件放入清洗籃，浸入專用的化油器/噴油嘴清洗液（通常是強效的碳垢清洗劑或水基脫脂劑）中。清洗液需要覆蓋所有零部件。

Choose the appropriate cleaning solution: Place the disassembled parts into a cleaning basket and immerse them in a specialized carburetor/fuel injector cleaning solution (usually a strong carbon scale cleaner or water-based degreaser). The cleaning solution needs to cover all components.

設定參數并啟動：工業級超聲波清洗機具備加熱功能，將清洗液加熱至50-60℃，設置清洗時間15-30分鐘（視積碳程度而定）。超聲波的高頻振動會產生空化效應，無數氣泡在零件表面和內部通道中爆破，將軟化和硬化的積碳一層層剝離。

Set parameters and start: The industrial grade ultrasonic cleaning machine has a heating function, which heats the cleaning solution to 50-60 ℃ and sets the cleaning time to 15-30 minutes (depending on the degree of carbon deposition). The high-frequency vibration of ultrasound generates cavitation effect, and countless bubbles burst on the surface and internal channels of the parts, peeling off the softened and hardened carbon deposits layer by layer.

漂洗與吹干：清洗完畢后，取出零件用清水徹底漂洗，去除殘留的清洗劑。最后用壓縮空氣吹干所有通道，確保沒有水分殘留。

Rinse and blow dry: After cleaning, remove the parts and thoroughly rinse them with clean water to remove any remaining cleaning agents. Finally, dry all channels with compressed air to ensure that there is no residual moisture.

清洗效果與注意事項

Cleaning effect and precautions

經過超聲波清洗的化油器，其內部通道會恢復原始尺寸，怠速量孔、主量孔通透如新；噴油嘴的噴孔則恢復最佳霧化狀態。許多維修案例表明，超聲波清洗后裝車，發動機怠速抖動明顯改善，加速響應更快，油耗也能恢復到接近新車水平。

After ultrasonic cleaning, the internal channels of the carburetor will return to their original size, and the idle and main measuring holes will be as transparent as new; The nozzle holes of the fuel injector return to the optimal atomization state. Many repair cases have shown that after ultrasonic cleaning and installation, the engine idle vibration is significantly improved, the acceleration response is faster, and the fuel consumption can be restored to near the level of a new car.

不過，操作時也需注意：對于帶有電磁線圈的噴油嘴，清洗前最好拆下線圈部分，只將閥體浸入清洗液，以免損壞電氣部件。對于化油器的塑料浮子和密封件，如果材質不耐清洗劑，也需提前取出。

However, attention should also be paid during operation: for fuel injectors with electromagnetic coils, it is best to remove the coil part before cleaning and only immerse the valve body in cleaning solution to avoid damaging electrical components. For the plastic float and seals of the carburetor, if the material is not resistant to cleaning agents, they should also be removed in advance.
