如何预防混凝土搅拌车积碳？
电子技术在混凝土搅拌车上的广泛应用，无疑使得车辆的安全性、可靠性、舒适性和燃油经济性都得到了显著的改善和提高，但是与此同时，也带来了不容忽视的积碳问题，而积碳对于车辆整体性能的影响是毋庸置疑的，因此，有效解决发动机的积碳问题，是延长发动机使用寿命，保障混凝土搅拌车车辆正常行驶的必要前提。那么，面对混凝土搅拌车发动机积碳的问题，我们应该如何预防呢？关于该问题，我们提出了以下几条预防建议。
The wide application of electronic technology in the concrete mixer truck undoubtedly improves the safety, reliability, comfort and fuel economy of the vehicle, but at the same time, it also brings about the problem of carbon deposition which can not be ignored. The impact of carbon deposition on the overall performance of the vehicle is beyond doubt. Therefore, to effectively solve the problem of carbon deposition in the engine is to extend The service life of the engine is the necessary premise to ensure the normal operation of the concrete mixer. So, facing the problem of carbon deposition in the engine of concrete mixer, how should we prevent it? On this issue, we put forward the following preventive suggestions.
注意熄火时机
Pay attention to the timing of flameout
对于装有涡轮增压器的混凝土搅拌车，在高速行驶或是爬坡后不要马上熄火，在怠速运转10分钟后再熄火，装有涡轮增压器的混凝土搅拌车其形成积碳的速度比一般自然吸气式的混凝土搅拌车要快数倍。建议混凝土搅拌车在常规保养都满足的条件下每2万至4万公里时做一下进气系统的免拆清洗，也就是在混凝土搅拌车发动机不解体的前提下用专用设备专用方法对搅拌车的进气道、气门、油路等容易形成积碳的部位进行清积碳的操作。
For the concrete mixer equipped with turbocharger, do not turn off the engine immediately after driving at high speed or climbing the slope, and then turn off the engine after idling for 10 minutes. The speed of carbon deposition of concrete mixer truck with turbocharger is several times faster than that of ordinary naturally aspirated concrete mixer. It is suggested that the air intake system of the concrete mixer should be cleaned every 20000 to 40000 km under the condition that the routine maintenance is met. That is to say, under the premise that the engine of the concrete mixer is not disassembled, the special equipment and special method are used to clean the air inlet, valve, oil way and other parts of the mixer which are easy to form carbon deposition.
使用清洁汽油
Use clean gasoline
汽油中的杂质是形成积碳的主要成分，所以清洁度高的汽油形成积碳的趋势就弱一些。但是要注意高标号并不等于高质量，标号只代表油的辛烷值，并不能代表品质和清洁程度。一些车主为了保障汽油清洁度，会采用在汽油里添加汽油清洁剂的做法。这样可有效地防止在金属表面形成积碳结层，并能逐渐活化原有的积碳颗粒并慢慢去除，从而保护混凝土搅拌车发动机免受伤害。不过汽油清洁剂的添加定要慎重，如果加入了伪劣的产品会得到相反的效果。
The impurity in gasoline is the main component of carbon deposition, so the tendency of carbon deposition in gasoline with high cleanliness is weaker. However, it should be noted that high grade is not equal to high quality. The label only represents the octane number of the oil, but not the quality and cleanliness. In order to ensure the cleanliness of gasoline, some car owners will add gasoline cleaner to the gasoline. This can effectively prevent the formation of carbon deposition layer on the metal surface, and gradually activate the original carbon particles and slowly remove them, so as to protect the concrete mixer engine from damage. However, the addition of gasoline cleaner must be careful, if you add fake products will get the opposite effect.
不要长时间怠速行驶
Don't idle for a long time
怠速时间长，混凝土搅拌车发动机达到正常温度所需的时间也就变长，汽油被喷到气门背面后蒸发的速度就慢，积碳也由此而生。同时经常怠速行驶，进入混凝土搅拌车发动机的空气流量也就小，这样对积碳的冲刷作用变得也很弱，会促进积碳的沉积。
The longer the idle time is, the longer it takes for the engine of the concrete mixer to reach the normal temperature. After the gasoline is sprayed to the back of the valve, the evaporation speed is slow, and carbon deposition is also generated. At the same time, when driving at idle speed, the air flow into the engine of the concrete mixer truck is small, so the scouring effect on carbon deposition becomes very weak, which will promote the deposition of carbon.
在混凝土搅拌车长时间运行的过程中，发动机产生积碳的问题虽是正常现象，且无法避免，但是需要明确的是，如果现象不是很严重也无需特别恐慌，只要在车辆保养过程中，密切注意观察车辆积碳的情况，并对其产生原因进行分析，积极采取防治措施，相信定能有效控制。
In the process of long-term operation of concrete mixer truck, the problem of carbon deposition in the engine is a normal phenomenon and can not be avoided, but it needs to be clear that if the phenomenon is not very serious, there is no need to panic, as long as the vehicle maintenance process, pay close attention to the situation of vehicle carbon deposition, and analyze its causes, actively take preventive measures, I believe it can Effective control.
