如何利用超聲波清洗機對發動機進行免拆清洗

作者：admin來源：http://www.dijiushangdian.cn/時間：2020-11-09

對于電噴車而言，免拆清洗時勿貪便宜目前市場上普遍采用的免拆清洗機清洗方式。其清洗是按噴油嘴的數量進行收費，一般一瓶清洗劑可以洗4個噴油嘴。需要注意的各種清洗劑的熱值是不同的另外由于其中化學添加劑的差別，劣質清洗劑在清洗過程中，會對噴油器的密封圈、三元催化劑造成一定損害，而且長時間清洗對發動機的相關零部件有利。

For EFI vehicles, do not be greedy for cheap when cleaning without dismantling. At present, the cleaning method of non disassembly cleaning machine is widely used in the market. The cleaning is charged according to the number of fuel injection nozzles. Generally, a bottle of cleaning agent can wash 4 spray nozzles. The calorific value of various cleaning agents that need to be noted are different. In addition, due to the difference of chemical additives, inferior cleaning agents will cause certain damage to the sealing ring of fuel injector and three-way catalyst in the cleaning process, and long-time cleaning is beneficial to the relevant parts of the engine.

目前市場上的免拆清洗有三種：清洗劑清洗、免拆清洗機清洗和超聲波清洗機。

At present, there are three kinds of non disassembly cleaning on the market: cleaning agent cleaning, cleaning machine cleaning and ultrasonic cleaning.

把清洗劑直接加入油箱里進行清洗

Add the cleaning agent directly into the oil tank for cleaning

只需要將合適的清洗劑加入油箱即可。但是目前市場上的清洗劑品種繁多，此種方法簡便易行。且規格不一，質量差的清洗劑由于熱值不同（一般都會偏大，燃燒時的溫度和壓力比汽油混合氣燃燒時要高，部件接受的熱負荷與機械負荷會增大）清洗過程中，容易對進排氣門、活塞、缸壁產生損害。

Just add the right cleaning agent to the tank. However, there are many kinds of cleaning agents on the market, so this method is simple and easy to operate. In addition, the cleaning agents with different specifications and poor quality are prone to damage the intake and exhaust valves, pistons and cylinder walls during the cleaning process due to different calorific values (generally, the temperature and pressure during combustion are higher than that of gasoline mixture combustion, and the thermal load and mechanical load of components will increase).

清洗過程因為要洗掉缸內的積碳，環保方面。所以尾氣排放肯定會暫時超標，清洗效果越明顯，其排放的尾氣濃黑劇烈，同時說明缸內的積碳已被大部分清洗掉了

the cleaning process because to wash away the cylinder carbon, environmental protection. Therefore, the exhaust emission will certainly exceed the standard temporarily. The more obvious the cleaning effect is, the more black the exhaust will be. At the same time, most of the carbon deposits in the cylinder have been cleaned

免拆清洗機清洗

用清洗劑替代油料燃燒對缸內的積碳進行清洗，免拆清洗機清洗的原理就是利用發動機本來系統的壓力及循環網絡。然后借排放系統排出。免拆清洗機的優點在于方便快捷，而且對于噴油嘴的清洗效果明顯；缺點是進氣道的前一段清洗不到而且噴油嘴的好壞也檢查不出來。對于新車而言，其清洗效果一般可以達到80%左右，舊車”沒有依照一定里程進行經常清洗的效果稍差，但洗后百公里的效果還是很明顯的

The principle of the cleaning machine is to use the pressure and circulation network of the original system of the engine. It is then discharged by the discharge system. The advantage of the cleaning machine is that it is convenient and fast, and the cleaning effect of the fuel injection nozzle is obvious; the disadvantage is that the front section of the intake port can not be cleaned and the quality of the fuel injection nozzle can not be checked out. For new cars, the cleaning effect can generally reach about 80%. The effect of "old cars" is not as good as that of "old cars" which are not cleaned regularly according to a certain mileage, but the effect after washing for 100 km is still very obvious

超聲波清洗機

與用清洗機不同，一般這種清洗的費用較高。要拆下噴油嘴。其優點在于，可以用超聲波對噴油嘴有無霧化、響應水平、開關靈敏度、否漏油等進行檢測。但其同樣也存在缺點，由于在清洗過程中噴油嘴的電磁閥不動，閥芯的針孔不容易被清洗到目前新款的超聲波清洗機，也可以給閥芯加上交流電，讓其打開并通過眼芯往復運動，對閥芯的清洗效果比擬好。

Different from cleaning machine, this kind of cleaning cost is higher. To remove the fuel injection nozzle. The advantage of this method is that ultrasonic can be used to detect whether the nozzle has atomization, response level, switch sensitivity and whether there is oil leakage. However, it also has disadvantages. Because the solenoid valve of the nozzle does not move during the cleaning process, the pinhole of the valve core is not easy to be cleaned. The new ultrasonic cleaning machine can also add alternating current to the valve core to make it open and move back and forth through the eye core, which has a better cleaning effect on the valve core.
