Comprehensive Engine Oil Filter Test Bench
Category：Filter Cartridge Filtration Tester
Introduction
Application
This test bench is designed for comprehensive evaluation of engine oil filters, including spin-on filters and filter bypass valves. It is suitable for:
Production quality control and factory testing
Research and development of engine oil filters
Verification of filter efficiency, pressure drop, and service life
Testing the performance of bypass elements and blocked filter behavior
The bench measures pressure drop, bypass characteristics, original filtration efficiency, and blocked filter life under controlled flow and temperature conditions.
Standards Compliance
The system is designed to meet the following standards:
JB/T 5088.2—2008 – Internal combustion engine spin-on oil filters
Section 6.2: Pressure drop – flow characteristic test
Section 6.3: Filter bypass element characteristic test
Section 6.6: Original filter efficiency test
Section 6.7: Blocked filter service life test
Notes:
Sections 6.2, 6.3, and 6.7 use CC30 diesel engine oil (temperature controlled below 100°C).
Section 6.6 uses 0# diesel or -10# light diesel at room temperature.
