Modern commercial vehicles are developing towards high-speed heavy duty and low emissions, which puts forward higher requirements for oil filters, air filters, fuel filters and other filters used in commercial vehicles.
Oil filter
The traditional main oil filter is mostly a full-flow filter, the filter flow resistance is generally small, the filtration accuracy is not high. For higher power and fuel economy, the oil filter is required to ensure the supply of oil and high filtration accuracy to ensure the normal operation of the engine performance. If the traditional oil filter is used, its life will be greatly shortened.
Full-flow shunt combined oil filter
The filter element of the new full-flow shunt combined oil filter is composed of two parts, one is the full-flow filter element, the flow resistance is small, the filtration accuracy is not high; The second is the shunt filter element, which has high filtration accuracy and large ash capacity, and large flow resistance. The full flow filter element with small flow resistance ensures the uninterrupted supply of oil, and filters impurities by the shunt filter element with high filtration accuracy.
Supercharger oil filter
Superchargers have a significant effect on improving engine power and improving emissions, and exhaust gas turbochargers have been widely used in modern commercial vehicles. Supercharger is very precise and high-speed operation, once the impurities enter, the supercharger will wear very quickly, so it is necessary to increase the special oil filter for the supercharger.
Centrifugal oil filter
The new centrifugal oil filter can effectively filter impurities. The rotor is designed for one-time use and can be replaced directly after its service life, making it easier to maintain. The parallel centrifugal oil filter in the lubrication system is of great help to reduce the impurity of the oil.
Fuel filter
Electronic control fuel injection system is widely used in modern commercial vehicle engines. Because the components of the electronic fuel injection system are more precise, especially the clearance between the precision pairs is very small, so higher requirements are put forward for the quality of fuel. Due to the reduced coordination gap, the fuel injection system is particularly sensitive to water and impurities in the fuel, so the fuel filter must have a high water separation efficiency and filtration accuracy.
Multi-tube swirl air prefilter
Commercial vehicles are mostly used in harsh environments, and traditional paper air filters are easy to clog, resulting in frequent maintenance and replacement of the air filter element. The new multi-tube swirl air pre-filtration device uses the centrifugal principle to separate dust from air, with a filtration efficiency of more than 85%, and with appropriate ash disposal, the filtration efficiency can reach 95%. Installing the air prefilter in front of the paper air filter can greatly extend the life of the paper filter element and reduce the number of maintenance and consumption.
In addition, this air prefilter does not need to be replaced, as long as it is cleaned regularly, it will not cause any adverse impact on the environment.
Water filter
According to statistics, 40% to 50% of engine failures are caused by the cooling system, to ensure the normal operation of the cooling system, can effectively reduce the engine failure rate, reduce maintenance costs. A new type of water filter has begun to be applied, and its role is to filter the impurities of the coolant and avoid the formation of scale in the engine cylinder liner.
With the continuous progress of technology, commercial vehicle filters will have more new products to provide more ideal protection for the engine and the whole vehicle.
