In recent years, excavators play an increasingly significant advantage in municipal projects, agricultural water conservancy and other construction, making a huge contribution to saving manpower and material resources, and can play a maximum production capacity in a small operating space. Such a small device but play such a big role. One thing that must be said is to do a good job of maintenance of the equipment. Let’s share excavators with bucket teeth wholesale. If our excavator has black smoke during operation, mainly in the case of insufficient fuel combustion, diesel fuel will be sprayed into the combustion chamber, which is not fully combusted. The high temperature decomposition of diesel fuel forms some carbon black. At this time when the excavator exhaust, it is easy to smoke black. There are many other conditions that can cause black smoke from excavators. One of the conditions that cause black smoke from excavators is the black smoke from incomplete combustion of fuel that we mentioned above. Also, when the combustion chamber is warped, it can be a quality problem.
This can cause the compression residual gap to be sometimes too large, sometimes too small, or the piston to be installed in the wrong position. At this point, it can affect the overall fuel to gas mixture ratio. Once this ratio changes, the fuel becomes anaerobic and builds up carbon, so the smoke that comes out is black.
If the excavator is emitting black smoke, it may be dripping fuel when the injectors are not atomizing properly. When this occurs, the fuel will not burn fully because the fuel will not mix more fully with the air. together.
The main reason for this is that worn valves or piston rings and cylinder liners in excavators can cause insufficient compression pressure, so the fuel will not burn well enough when it does. Therefore, we need to check the valve piston ring or cylinder liner in time during maintenance, and replace worn ones immediately!
