1. Black smoke when the diesel engine is working
First, pay attention to checking the air supply system. If the diesel engine does not have enough air intake, the amount of air in the combustion chamber cannot meet the requirements, which will cause the diesel to not burn fully. When the diesel cannot burn fully, it is very easy to produce black smoke under high pressure. At this time, the intake duct and air filter must be checked to see if there is any blockage, whether the supercharger is operating normally, and whether there is any leakage in the intake pipe. At the same time, check the correctness of the valve to ensure that there is no leakage problem in the intake and exhaust valve seats, and the intimacy problem of the piston, cylinder liner, and piston ring. Second, pay attention to checking the diesel supply system. When the diesel engine is poorly supplied with fuel, it will affect the later mixing. Even if it reaches a full intake state, it cannot be completely burned, and black smoke will be generated at this time. During the inspection process, the following points must be noted: Pay attention to checking the high-pressure oil pump to ensure that it meets the standard requirements. Pay attention to checking the fuel supply to avoid excessive fuel supply. Pay attention to checking the operating status of the oil outlet valve to ensure that it is in good condition. Pay attention to checking the poor atomization caused by insufficient injector pressure. Pay attention to checking the secondary injection and oil leakage of the injector. Pay attention to checking the problem of too many injector gaskets and substandard fuel injection. Pay attention to checking diesel performance and quality.
2. Insufficient power of diesel engine
During the operation of diesel engine, it is very easy to have insufficient power problem. When encountering such problems, multiple methods must be used to determine the cause of the fault. First, check the smoke and wear problems. During the operation of the engine, open the oil cap. When thick smoke is found, it means that the diesel engine has a serious problem of lower smoke, indicating that the cylinder liner, piston, piston ring and other parts are seriously worn. When the valve cover is opened, when cyan smoke and white smoke appear at the root of the valve, it means that upper smoke occurs. When serious upper smoke occurs, it means that the valve and valve seat are severely burned and worn, and it may also be caused by a relatively small valve clearance or no clearance. By observing the upper smoke phenomenon, it can be observed which valve or cylinder has a leakage problem, and measures must be taken in time to deal with it. Second, check carbon deposits and working conditions. When black carbon deposits appear at the exhaust port of a diesel engine, similar to a layer of white frost, and the thickness is thin, it means that the diesel engine is in good running condition. When black and bright carbon deposits appear, but the carbon deposits are not wet, it indicates that the diesel engine oil is highly consumed, and the carbon deposits must be thoroughly cleaned. When the thickness of carbon deposits at the cylinder exhaust port is significantly greater than that at other cylinder exhaust ports, it means that the cylinder injector is not in good operating condition, and the cylinder may not be sealed well, so it must be inspected and replaced. For individual exhaust ports, when they are wet or oily, it means that there is a large amount of oil discharge inside the cylinder, and repairs must be done in time. When the thickness of carbon deposits at the cylinder exhaust port is large and the color is dark, it means that the temperature is low and the fuel injection is not in place, resulting in serious afterburning problems in the diesel engine. It is necessary to ensure that the diesel engine is operated correctly and make optimization adjustments.
