1. Gasoline engine intake valve deposit simulation test machine parameters: Test duration of 85 minutes; test temperature of 175°C; temperature control accuracy of ±1°C, with an automatic control system display precision of 0.1°C.
2. Air supply: air pressure of (80 ± 1) kPa, air flow rate of (700 ± 20) L/h;
3. The flow rate of the gear pump allows 300 mL of test base oil to be dispensed within 73 to 75 minutes;
4. The gear pump output flow does not exceed 6 mL/min, with a flow control accuracy of ±0.02 mL/min;
5. The instrument is equipped with an exhaust gas absorption system. The exhaust gas generated during testing passes through a condensation unit and is filtered by an activated carbon filter to meet emission standards (VOCs content not exceeding 200 mg/L) before being released. The sample recovery cup recovers no less than 70 mL of waste oil per test.
6. Equipped with a 16-megapixel camera system;
7. Exhaust gas recovery: more than 70 ml per time.
8. Fuel supply timing: 75 min; heating maintenance: 10 min.
The imaging workstation employs high-resolution electronic imaging technology to photograph, edit, and automatically save completed sedimentation plates, generating formatted test reports with images and text. It also enables real-time retrieval of historical data and reports, facilitating traceability of results in later stages. The figure below shows the generated图文 test report.
