In the new car quality assurance period, should not use filter (filter core) substitutes, even after the quality warranty period, also want to carefully choose filter. Diesel filters are rated according to ISO standards. In addition to the SAE standard performance test, the air filter element must also be tested on a bench to meet the requirements of the rated intake of the engine, such as the original intake resistance. Qualified oil filter must meet the original design of engine cylinder pressure, oil temperature, flow, viscosity and vehicle service conditions, and to consider the overall balance of core quality. The nominal filtration accuracy is indicated on the product samples or nameplates of the manufacturers of hydraulic oil filter elements, but not the absolute filtration accuracy. Only the beta value determined by the test can indicate the filtration capacity of filter gong. The hydraulic oil filter element should also meet the requirements of pressure loss (the total pressure difference of the high-pressure filter is less than 0.1pma, and the total pressure difference of the oil return filter is less than 0.05mpa) to ensure the optimal flow rate and filter element life.
　　In the selection of filter (filter element) can choose the original parts, can also choose the second brand. It should be noted that the selected filter element should be accepted to check whether it conforms to its performance indicators.
