In the new car quality assurance period, should not use the filter (filter element) substitute, even after the quality warranty period, but also carefully choose the filter. Performance of diesel filters is graded in accordance with ISO standard. In addition to the SAE standard intake performance test, the air filter element should also be tested on the bench to meet the original intake resistance of the rated air intake of the engine. Qualified oil filters must conform to the original design of the engine cylinder pressure, oil temperature, flow, viscosity and vehicle conditions, and to consider the core quality of the comprehensive balance. The nominal filtration accuracy, rather than the absolute filtration accuracy, is indicated on the product sample or nameplate of the manufacturer. Only the value measured by the pass test can indicate the filtration capacity of the filter bead. The hydraulic oil filter element should also meet the pressure loss requirements (the total pressure difference of the high pressure filter is less than 0.1PMA, and the total pressure difference of the return oil filter is less than 0.05mpa), in order to ensure the optimization of flow rate and the life of the filter element.
