What are the Hazards Caused by Carbon Deposits in Shangchai Generators

Carbon deposits on Shangchai gensets are the product of incomplete combustion of diesel oil and engine oil that has entered the combustion chamber. It is commonly found on the top of diesel engine pistons, the walls of the combustion chamber and around the valves. A large amount of carbon deposits in Shangchai generators may not only lead to poor combustion, deterioration of heat transfer, and accelerated parts wear, but also reduce the working performance of the diesel engine and reduce the reliability of the unit. In this article, generator manufacturer-Dingbo Power introduce to you several hazards caused by a large amount of carbon deposits in Shangchai generators.

1. Increase the compression ratio of the diesel engine. Excessive adhesion of carbon deposits on the cylinder wall and piston will reduce the volume of the combustion chamber and increase the compression ratio, resulting in a decrease in the power of the diesel engine. It is also easy to cause diesel engine deflagration, knocking, damage parts, and shorten the service life of Shangchai generators.

2. Increase the temperature of the diesel engine. Carbon deposition is a poor conductor of heat. When the combustion chamber and the top of the piston are covered with a layer of carbon deposition, the heat generated by the Shangchai generator cannot be dissipated in time, causing the temperature of the diesel engine to rise sharply. The overheating of Shangchai generators will cause many undesirable effects on its work, such as deterioration of lubricating oil, increased wear and tear, and thermal deformation and seizure of mechanical parts.

3. When carbon deposits accumulate on the working surface of the valve and seat ring of Shangchai generator, the valve will not close tightly and cause air leakage; when carbon deposits on the valve guide and valve stem are glued, it will accelerate the gap between the valve stem and the valve guide Of wear.

4. If carbon deposits adhere to the nozzle of the fuel injector, the nozzle hole will be blocked or the needle valve will be stuck, resulting in poor fuel atomization and incomplete combustion.

5. When carbon deposits in the piston ring groove, the edge clearance and backlash of the piston ring will become smaller, or even no gap. At this time, it is very easy to cause the piston ring to cement and lose its elasticity, pulling the cylinder, or even breaking the piston ring.

6. Severe carbon deposits in the exhaust ducts of Shangchai generators and the inner wall of the exhaust pipe muffler will increase the exhaust resistance of the diesel engine, increase the exhaust resistance in the cylinder, and make the exhaust unclean.

We not only need to understand the harm caused by carbon deposits to the generators, but also the reasons for the formation of carbon deposits in the generators, and we should pay attention to them during use. Standard operation can reduce the formation of carbon deposits to a certain extent and improve the working efficiency of Shangchai generators.

This is the harm caused by a large amount of carbon deposits in the Shangchai generators complied by Dingbo Power.
