如何預(yù)防混凝土攪拌車積碳？
電子技術(shù)在混凝土攪拌車上的廣泛應(yīng)用，無疑使得車輛的性、可靠性、舒適性和燃油經(jīng)濟性都得到了顯著的改善和提高，但是與此同時，也帶來了不容忽視的積碳問題，而積碳對于車輛整體性能的影響是毋庸置疑的，因此，有效發(fā)動機的積碳問題，是延長發(fā)動機使用壽命，保障混凝土攪拌車車輛正常行駛的必要前提。那么，面對混凝土攪拌車發(fā)動機積碳的問題，我們應(yīng)該如何預(yù)防呢？關(guān)于該問題，我們提出了以下幾條預(yù)防建議。
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.
注意熄火時機
Pay attention to the timing of flameout
對于裝有渦輪增壓器的混凝土攪拌車，在高速行駛或是爬坡后不要馬上熄火，在怠速運轉(zhuǎn)10分鐘后再熄火，裝有渦輪增壓器的混凝土攪拌車其形成積碳的速度比一般自然吸氣式的混凝土攪拌車要快數(shù)倍。建議混凝土攪拌車在常規(guī)保養(yǎng)都滿足的條件下每2萬4萬時做一下進氣系統(tǒng)的免拆清洗，也就是在混凝土攪拌車發(fā)動機不解體的前提下用專用設(shè)備專用方法對攪拌車的進氣道、氣門、油路等容易形成積碳的部位進行清積碳的操作。
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.
使用清潔汽油
Use clean gasoline
汽油中的雜質(zhì)是形成積碳的主要成分，所以清潔度高的汽油形成積碳的趨勢就弱一些。但是要注意高標號并不等于高質(zhì)量，標號只代表油的辛烷值，并不能代表品質(zhì)和清潔程度。一些車主為了保障汽油清潔度，會采用在汽油里添加汽油清潔劑的做法。這樣可有效地防止在金屬表面形成積碳結(jié)層，并能逐漸活化原有的積碳顆粒并慢慢去除，從而保護混凝土攪拌車發(fā)動機免受傷害。不過汽油清潔劑的添加定要慎重，如果加入了偽劣的產(chǎn)品會得到相反的效果。
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.
不要長時間怠速行駛
Don't idle for a long time
怠速時間長，混凝土攪拌車發(fā)動機達到正常溫度所需的時間也就變長，汽油被噴到氣門背面后蒸發(fā)的速度就慢，積碳也由此而生。同時經(jīng)常怠速行駛，進入混凝土攪拌車發(fā)動機的空氣流量也就小，這樣對積碳的沖刷作用變得也很弱，會促進積碳的沉積。
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.
在混凝土攪拌車長時間運行的過程中，發(fā)動機產(chǎn)生積碳的問題雖是正常現(xiàn)象，且無法避免，但是需要明確的是，如果現(xiàn)象不是很嚴重也無需特別恐慌，只要在車輛保養(yǎng)過程中，密切注意觀察車輛積碳的情況，并對其產(chǎn)生原因進行分析，積極采取防治措施，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.
