The loader emits smoke under normal working conditions. There are many reasons for this phenomenon. Common reasons are as follows:
If the loader emits white smoke, it may be:
1. Check whether there is water in diesel, whether there is water in diesel, or whether there is water in diesel, which directly affects the normal combustion of mixed gas and produces white smoke. At this time, the bottom mud oil should be released and drained, and the diesel oil should be replaced if necessary.
2. The exhaust pipe seems to continue to emit white smoke. It may be that the cylinder head and cylinder head of individual cylinders are damaged, and the water should be taken out. The damaged cylinder head and cylinder head should be replaced. In addition, if the intake valve is not closed tightly, white smoke may appear, and should be checked and repaired.
3. When the fuel supply propulsion angle is too small and the temperature of the diesel engine is not high, part of the fuel will not burn and will be discharged with the exhaust gas, and the oil mist will form white gas.
4. The engine temperature is not enough. The mixture of fuel and air in the cylinder is not burned out, and the exhaust pipe emits white smoke. Note that after the locomotive starts, pay attention to the insulation of the water tank and operate the middle throttle valve to make the locomotive temperature reach 50 ℃. When C is up, the load gradually increases.
5. The cylinder head gasket is broken, the water channel or the cylinder liner is cracked, and the cooling water continuously penetrates into the cylinder block. When the exhaust gas is discharged, the discharged hot air flow evaporates or disperses to form water mist or water vapor, and is discharged in the form of white smoke.
If it is blue smoke, the main reason is caused by burning oil, the specific analysis is as follows:
1. There is too much oil in the air filter. There is too much oil in the filter pan. In the case of a hot car, the engine oil becomes thinner, which easily enters the cylinder and burns, causing the engine to emit blue smoke. The piston ring should not exceed the oil level in the oil pan. Facing the ring groove.
2. There is too much oil in the pan. The amount of oil in the oil pan is too large, and the amount of oil on the cylinder wall increases accordingly. Some oil is squeezed out of the piston ring gap into the combustion chamber, producing blue smoke. Therefore, the oil in the oil pan should not exceed the upper mark of the oil gauge.
3. When the piston ring is worn or worn, the gap between the cylinder and the cylinder liner is too large. When the piston ring is cemented with carbon deposits, the oil on the cylinder wall cannot be completely scraped off; the wear of the piston ring and the gap between the cylinder liners are too large, which reduces the oil's ability to scrape. Blue smoke, can drain the oil in severe cases.
4. The overhauled cylinder liner and piston set are not suitable for new cars or locomotives. The cylinder liner, piston, and piston ring do not fit. At the beginning of the work, the piston ring cannot wipe off the oil on the cylinder wall. Blue smoke. However, after a period of running-in, it can eliminate itself.
