Troubleshooting of white smoke from diesel generators
When the diesel generator sets smoke during startup and operation, you should first check and debug the temperature in the engine room. When the engine temperature rises above ℃, if the white smoke is not there yet To alleviate the problem, check whether there is water in the fuel tank. If there is water, the oil in the diesel filter and fuel tank should be drained, and good fuel should be added before starting the test. If the fuel is good, check whether the oil in the crankcase contains water.
The characteristics of water in engine oil are: firstly, there are water droplets in the oil; secondly, when the engine is running, the oil has yellowish-white foam.
In this regard, we should focus on checking whether the cylinder liner of the generator set, including the cylinder liner sealing ring and cylinder gasket, is cracked, allowing cooling water to penetrate into the crankcase and combustion chamber. Find out the cause and replace or repair it.
Troubleshooting of blue smoke from diesel generator set
When the diesel generator set emits blue smoke, you should first check the oil level in the crankcase. If the oil level is too high, excess oil should be drained. If it is normal, the cylinder compression force should be checked. If the cylinder pressure is much lower than the specified value, it means that the gap between the piston ring and the cylinder wall is too large. If the generator set is newly repaired, it is possible that the piston rings are installed incorrectly.
In addition, if the air filter is clogged, the air intake is not smooth during the intake stroke, and the oil in the air filter may be sucked into the combustion chamber. In this case, the air filter should be removed, as normal instructions Here's the glitch.
Troubleshooting of black smoke from diesel generator set
When the diesel engine emits black smoke, the oil cut-off method should be used first to cut off the oil supply to each cylinder in turn. If the oil supply to each cylinder is cut off, the diesel engine speed and The sound changes are particularly obvious, the smoke phenomenon is reduced or disappeared, the vibration is reduced, and the generator cycle rate drops significantly, indicating that the fuel supply of the cylinder is too large. On the contrary, the fuel supply will be small.
Secondly, use the rapid acceleration method. After the engine is started, quickly pull the speed control handle from idle speed to high speed. If the engine speed cannot keep up, the sound is dull and rough, and the black smoke is serious, it means that the fuel injection time is late. On the contrary, the engine The speed catches up quickly, the sound is sharp and crisp, and the work is rough, accompanied by the sound of cylinder knocking and blue smoke, indicating that the fuel injection time is too early.
In addition, you can also check whether the timing mark on the flywheel is correct. For example, the injection timing of a diesel engine is at ~ crankshaft angle. If the above is normal, stop the machine and use a screwdriver to pry the plunger tappet to check. When prying, if the injection sound of the injector is small and feels no pressure or the pressure is small, it means that the injection pressure is low or the atomization is not good.
