Used Bulldozer in the daily work, if the phenomenon of black smoke, generally because the combustion of fuel in the combustion chamber is not completely fully combusted, resulting in the formation of carbon smoke at high temperatures. This carbon smoke is a very small diameter aggregate, due to the high temperature and lack of oxygen environment in the combustion chamber, can not be fully combusted again, it will be discharged through the exhaust pipe, so the presentation is black smoke.
The direct consequence of this phenomenon is that the diesel engine’s fuel consumption is very high, the power is reduced, and at the same time make the piston, piston rings and valves a large number of carbon deposits exist. Serious times will be stuck piston rings, valve sealing and produce air leakage, while accelerating the wear and tear of parts, thereby reducing the service life of the engine, so this aspect should pay special attention to.
Fuel system problems are one of the possible causes. Because the fuel pollution or too much, will lead to the injector can not be completely injected into the fuel, thus causing incomplete combustion of fuel, producing a lot of black smoke. In this case, a maintenance operation such as cleaning and filter replacement is needed to ensure that the fuel is properly injected and the amount of fuel supplied is controlled at the same time.
Engine problems are also important factors affecting the performance of the bulldozer. For example, the cylinder block, piston, ring and other parts of the wear or aging and other problems will lead to engine performance decline, which in turn leads to the bulldozer power is not enough to push the bucket plate to move the material, which is also a performance of “no power”. This is also a sign of “lack of energy”. At this time, it is necessary to carry out engine maintenance and replacement of worn parts, so as to improve the efficiency of the engine.
Hydraulic system problems may also lead to Used bulldozers smoke and no power. For example, the hydraulic oil pressure is insufficient or the oil viscosity is too thick and other problems will affect the normal work of the hydraulic system. Therefore, you need to regularly check the oil quality and pressure of the hydraulic system and perform the necessary repair and replacement operations to ensure the normal work of the used bulldozer.
Poor performance of the used bulldozer may affect the progress and efficiency of construction operations, requiring engineering and technical specialists to carry out on-site overhaul and maintenance of various problems, as well as maintenance and repair of the used bulldozer’s components to ensure that the used bulldozer operates at an optimal level.
