Causes of Perkins diesel exhaust pipe injection diesel.
As a widely used diesel engine, Perkins diesel engine may have the phenomenon of exhaust pipe diesel injection during long-term use. The occurrence of this phenomenon will not only affect the normal operation of the engine, but also may cause certain pollution to the environment. Therefore, it is of great significance to understand the reasons for Perkins diesel engine exhaust pipe injection and take corresponding measures to prevent and solve it to ensure the normal operation of the engine and protect the environment.
First, the injector is not working well.
Poor injector work is one of the common causes of Perkins diesel exhaust pipe injection. In the process of long-term use, due to the influence of high temperature, high pressure, fuel corrosion and other factors, the injector is prone to poor atomization, oil leakage and other phenomena, resulting in the decline of the injector's working performance. When the injector is working poorly, the diesel fuel injected into the cylinder cannot be burned sufficiently, causing part of the diesel fuel to be discharged through the exhaust pipe.
To solve this problem, the following measures can be taken:
1.Regularly inspect and clean the injector to ensure that it is working properly;
2.Replace the fuel filter regularly to prevent impurities in the fuel from clogging the injector;
3.Adjust the injection pressure and atomization effect of the injector to make it meet the working requirements of the engine.
Second, the oil supply angle is not properly adjusted.
The oil supply advance angle is one of the important parameters that affect the engine performance, and too large or too small the oil supply advance angle may cause the engine to work abnormally. If the advance angle of fuel supply is not adjusted properly, the diesel fuel injected into the cylinder will not be fully combusted, and part of the diesel fuel will be discharged through the exhaust pipe, resulting in the phenomenon of diesel fuel injection from the exhaust pipe.
To solve this problem, the following measures can be taken:
1.Regularly inspect and adjust the oil supply advance angle to ensure that it meets the working requirements of the engine;
2.Use qualified diesel fuel to prevent the poor quality of diesel from causing abnormal fuel supply advance angle;
3.Regularly inspect and maintain your engine's fuel system to ensure it is working properly.
3. The compression pressure of the cylinder is insufficient.
The insufficient compression pressure of the cylinder is also one of the reasons for the injection of diesel fuel in the exhaust pipe of Perkins diesel engine. Insufficient cylinder compression pressure will cause insufficient temperature and pressure in the cylinder, so that the diesel cannot be fully combusted, and part of the diesel fuel is discharged through the exhaust pipe.
To solve this problem, the following measures can be taken:
1.Regularly inspect and maintain the cylinder and piston components of the engine to ensure that they are working properly;
2.Adjust the valve clearance and valve spring tension to ensure the intake and exhaust effect of the cylinder;
3.Regularly inspect and maintain the engine's intake and exhaust systems to ensure they are unobstructed.
To sum up, the reasons for the exhaust pipe of Perkins diesel engine mainly include poor injector work, improper adjustment of fuel supply advance angle and insufficient cylinder compression pressure. In order to solve this problem, it is necessary to take corresponding measures to prevent and solve it, such as regularly inspecting and adjusting the various components of the engine, using qualified fuel and accessories, etc. At the same time, the operator also needs to pay attention to the correct maintenance and use in accordance with the operating procedures to prolong the service life of the engine and reduce the pollution to the environment.
