Structure of the Oil Filter
Housing: Made of metal or high-strength plastic, it withstands oil pressure and protects the inner filter element.
Filter Element:
Material: Paper, metal mesh, synthetic fiber, or felt.
Filtration Accuracy: Typically 5~30μm (paper filter elements have higher accuracy).
Bypass Valve (Safety Valve):
Opens automatically when the filter element is clogged, ensuring that oil can still flow even without filtration (to prevent engine oil starvation).
Seal: Ensures a leak-proof seal between the filter and the engine, preventing oil leaks.
