If the carbon deposition of concrete mixer truck is light, it will affect the work efficiency, and if it is heavy, it will cause damage to the vehicle. So, how should we prevent it?

1、不要长时间怠速行驶

1. 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.

2、注意熄火时机

2. 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2万4万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混凝土搅拌车的进气道、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 concrete mixer which are easy to form carbon deposition.

3、使用清洁汽油

3. 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。一些车主为了保证汽油的清洁度，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一定要慎重，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 use the method of adding gasoline cleaner to 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.

以上介绍的就是预防混凝土搅拌车积碳的方法，希望对大家有帮助，如果已经发生了积碳现象，建议大家及时处理

The above is to prevent the concrete mixer car carbon deposition method, I hope to help you, if there has been carbon deposition phenomenon, we suggest that you deal with it in time
