Well-designed engine oil filtration system is closely related to the service life of the oil

Some industrial engines are designed for the use of gaseous fuels (such as natural gas). Although similar to diesel engines, these engines have been modified so that combustion reactions in cylinders are initiated by sparks, which is different from real diesel engines. The actual industrial diesel engines used have reciprocating pistons. The diesel engine can be either two-stroke or four-stroke. According to the arrangement of the cylinders, the fuel engine can be divided into vertical, horizontal or inclined angles, such as a V-shaped engine. Which type of engine is used in the industry depends on the requirements for engine power, deadweight, and size. The main role of engine oil in the engine is to reduce friction, absorb frictional heat, and cool the engine.

In order to meet the design requirements of different types of engines, a series of engine oils with viscosity and quality grades have been developed. In order to reduce the formation of deposits and coke, all engine oils must have good thermal oxidation stability to extend the oil change period. Well-designed engine oil filtration systems are also closely related to the service life of the oil. The role of oil in addition to reducing friction, there is also the removal of metal wear particles between the small gaps on the surface of the movement, to maintain the role of clean. The product of wear particles and fuel combustion must remain in suspension in the oil to be filtered out by the engine oil filter unit. The conditions of the diesel engine during operation are varied, including a low speed, stable, and a medium speed variable output, a high speed, high output. Because the role of oil cleanliness in the engine is important, the oil must contain a clean dispersant. Engines with high compression ratios tend to accelerate the formation of oil deposits. Engine oils with high-definition cleanliness can keep the piston clean, reduce the wear rate between the cylinder and piston rings, and prolong the service life of the engine. Detergents prevent the decomposition products from depositing on piston rings, pumping circuits, and other devices. The oil temperature has a significant effect on the dispersion, and it is difficult to achieve a good dispersion effect at low temperatures. However, for a high-power output of diesel crankcase oil, low temperature dispersion is often the most basic requirement.
