Engine oil lubricates all functional parts that move inside the engine. As a result of combustion, various dirt and combustion waste particles such as soot are mixed into the engine oil. These contaminate the oil and reduce its fluidity. In this case, the oil cannot do its job properly and especially its corrosion protection function is reduced. As a result, engine performance decreases and fuel consumption increases. In the worst case, the engine will be damaged.

High engine performance and low fuel consumption place very high expectations on engine manufacturers. Only clean oil can keep the engine performance at the same level all the time. The oil filter should be changed in time. If the oil filter is changed regularly, only clean oil will circulate in the system. This greatly increases engine efficiency and provides reliable protection against wear. Because oil filters have to meet different requirements in various fields, they can be of various shapes.

Oil Filter Elements: Oil filter elements are either placed in their own housing or integrated directly into the engine lubrication system. In this case, since only the filter element is changed, it is especially sensitive to the environment. The housing and valves remain on the engine block. The exact placement of the oil filter elements in the housing ensures that the filters are completely sealed.

Atomic Oil Filters: Atomic oil filters form a one-piece unit that includes the body and filter element. The entire unit is replaced during maintenance. The following parts can be integrated:

- One Way Valve: It prevents the oil in the oil channels and filter from flowing back to the crankcase when the engine is stopped, and ensures that there is oil in the channels when the engine is started.

- Bypass Valve: It ensures that the oil goes to the channels in case of sudden increase in oil pressure when the engine is cold started, or in case of clogging of the oil filter for any reason, for example by exceeding the maintenance interval.

- Disassembly - Installation Threads: Allows you to quickly and effectively remove and install the oil filter with the disassembly - installation tools.

Special Designs; Like Transmission Filters

Main Flow Filter: Main flow filters are placed in the circulation system, all the oil that needs to be cleaned reaches the system after passing through the filter.

Combined Main and Auxiliary Flow Filters: 90-95% of the oil is transmitted to the system through the star-shaped filter of the main flow filter, 5-10% through the bypass filter or the centrifugal filter moving with oil pressure. Thus, precise and sensitive filtering is ensured.

The high proportion of soot particles in diesel engines reduces the quality of the engine oil. As the oil becomes dirtier, its viscosity increases (it becomes less fluid) and less effective.

Contaminated lubricating oil increases wear on the engine and reduces engine life. Damage to the bearings cannot be prevented as overused oil cannot provide sufficient lubrication. Auxiliary flow filters are important to cope with the increased soot content in the lubricating oil and also to extend the maintenance intervals. In the bypass system, 5-10% of the lubricating oil passes through very fine untreated cotton material or paper material, or is filtered by a centrifugal filter with a motor made of steel and/or plastic, moving with oil pressure. Thus, the amount of soot in the oil circuit is reduced.

Depending on the centrifugal filter size, oil pressure and viscosity, it reaches more than 10,000 revolutions. The centrifugal filter processes about 10% of the oil. Efficiently separates particles of all sizes that have a greater density than lubricating oil. This means that it can separate soot particles smaller than one thousandth of a millimeter from the oil.
