Carbon deposition can be said to be the enemy of the engine. The reasons for the coke deposition in the diesel engine are complicated. It is closely related to the diesel engine structure, fuel oil, lubricating oil types, working conditions and working conditions.

Today we're talking about the relationship between lubricants and carbon deposits. After running for a period of time, the Baotou North rush heavy truck parts, cylinder head, cylinder liner, piston, piston ring, valve, fuel injector and other parts, as well as combustion chamber surface will adhere to a layer of carbon deposits;

It is a product of fuel and lubricating oil of high temperature oxidation of diesel engine in operation, in the operation of diesel engines, the combustion chamber due to insufficient oxygen supply, diesel oil and lubricating oil on the incomplete burning of generated smoke and tar particles, they mixed together with lubricating oil oxidation gelling liquid, carboxylic acid.

The carboxyl acid is further oxidized to a resin form, and the gum is firmly attached to the machine parts. Under the influence of high temperature, the colloidal polymer is synthesized with cemented carbide, which is called carbon deposition.

The main components of carbon deposits are lubricating oil, carboxyl acid, asphaltene, oil, gum, sulfate, silicide, etc. the higher the temperature of diesel engine, the more hard and tighter the coke formed, and the stronger the bond with metal.

Baotou beiben heavy truck engine accessories long-term operation to produce carbon and burning the residue will be attached to the inside of the engine everywhere, without proper treatment, it will affect Baotou beiben heavy truck engine parts especially these things gathered in the piston ring and the exhaust valve etc., will produce coke or adhesive material.

The oil itself has a quiet, dispersing effect that keeps the carbon and debris from accumulating inside the engine, allowing them to form small particles that are suspended in the oil.

That's what we've always understood about the cleanliness of the oil. Therefore, the engine oil cleaning ability is good oil.

The crankcase simulation tester is to evaluate the oxidation stability, detergency, corrosion resistance, evaporation loss and oil sludge characteristics of additives and additives;

The machine has a heating oil tank, which will test the oil heated to 150 degrees, while the upper part of a heating plate will take the sample heated to more than 300 degrees, 6 hours of continuous operation, or operation of 15 seconds for 45 seconds, similar to simulate the actual working condition, check the oil gelling, carbonization conditions.

According to the different oil experiments, we found that the oil gelling, carbonation will not have the same synthetic oil is better than mineral oil, it also tells us a truth, about the relation between oil and coke, in addition to a good cleaning ability, its own characteristics also inhibit coke formation very important.
