The solution to the problem of exhaust oil under the Carter diesel engine.
As an efficient and reliable engine type, Catter diesel engines are widely used in a variety of machinery and vehicles. However, there are times when there is a problem with the lower exhaust oil, which not only affects the normal operation of the engine, but can also cause damage to the machinery. This article will analyze the causes of exhaust oil under Carter diesel engines and propose corresponding solutions.
First, the reason for the exhaust oil under the Carter diesel engine.
There are several causes of exhaust oil under a Carter diesel engine, the most common of which are worn or broken piston rings, faulty crankcase forced ventilation system, damaged cylinder gaskets, and faulty superchargers.
1.The piston rings are worn or broken.
The piston ring is one of the most important parts in the engine, and its main role is to seal the cylinder and prevent gas leakage and oil mixing. If the piston rings are worn or broken, it will cause the cylinder to be poorly sealed and the lower exhaust to drain the oil.
2.Failure of the crankcase forced ventilation system.
The main function of the crankcase forced ventilation system is to extract the gas in the crankcase and introduce it into the intake pipe to mix with the fuel for combustion. If this system fails, it causes the pressure inside the crankcase to rise, allowing the oil to enter the cylinder through the piston ring and exit with the lower exhaust.
3.The cylinder head gasket is damaged.
A cylinder head gasket is a gasket between the cylinder and the cylinder head, and its role is to prevent gas leakage and oil mixing. If the cylinder gasket is damaged, the seal between the cylinder and the cylinder head will fail, allowing the oil to enter the cylinder and drain with the lower exhaust.
4.Faulty supercharger.
The role of the supercharger is to increase the air intake of the engine by compressing the air, thereby increasing the power and torque of the engine. If the supercharger fails, it will result in insufficient air intake, which will cause the engine to run abnormally and drain the oil from the exhaust.
Second, the solution of Carter diesel engine exhaust oil under the exhaust oil.
In response to the above problems, we can take the following solutions:
1.Replace the piston rings.
If the piston ring is worn or broken, a new piston ring needs to be replaced. When replacing the piston ring, it is necessary to pay attention to the installation direction and sequence of the piston ring to ensure the sealing performance.
2.Overhaul the crankcase forced ventilation system.
If the crankcase forced ventilation system fails, the ventilation ducts and vent valves need to be checked to see if they are working properly and repaired or replaced if necessary.
3.Replace the cylinder head gasket.
If the head gasket is damaged, it needs to be replaced with a new one. When replacing the cylinder head gasket, it is necessary to ensure the degree and sequence of the cylinder head screws to avoid cylinder head deformation or poor sealing.
4.Overhaul the supercharger.
If the supercharger fails, it is necessary to check that the intake lines of the supercharger, compressor wheels and turbine wheels and other components are working properly, and if necessary, repair or replace them.
3. Preventive measures.
In order to avoid the problem of exhaust oil under the Carter diesel engine, the following precautions can be taken:
1.Regularly inspect and maintain components such as the crankcase forced ventilation system and cylinder head gasket to ensure their proper operation.
2.Choose oil and fuel that meet the specifications and avoid using inferior or counterfeit oil and fuel.
3.The engine is serviced and maintained according to the specified time and mileage to ensure the normal operation of the engine.
