1984 Mercedes Turbo Diesel Emissions Test

Testing the Waste Gas Emissions of a Mercedes Benz Turbo Diesel Under Different Driving Conditions

This emissions test was conducted under 40 CFR Part 86 of the Federal Test Guide to measure the impact of Cerma STM-3 engine treatment on diesel exhaust emissions.

Test Certification & Standards

All personnel, tests, testing equipment, and testing facilities used for these tests are both EPA and California Air Resource Board (CARB) certified.

Emissions Measured

Samples of the emissions are collected in bags and analyzed for:

  • THC – Total Hydrocarbons
  • CO – Carbon Monoxide
  • NOx – Nitrogen Oxides
  • CO2 – Carbon Dioxide
  • Fuel Economy – MPG measurement

Test Review Protocol

Baseline Testing (Steps 1-12)

  1. Drain existing fuel in test vehicle
  2. Fill tank to 40% with specified test fuel (test diesel)
  3. Run Prep cycle
  4. 12-hour controlled soak
  5. Run CVS/FTP test for baseline (1)
  6. Run second Prep cycle
  7. 12-hour controlled soak
  8. Run second CVS/FTP test for baseline (2)
  9. Run third Prep cycle
  10. 12-hour controlled soak
  11. Run third CVS/FTP test for baseline (3)
  12. Make sure the three baselines are repeatable within a 10% tolerance

Testing with Oil Catalyst (Steps 13-21)

  1. Add liquid oil catalyst (Cerma STM-3)
  2. Drive 100 miles using AMA Route
  3. Reconstitute test fuel to 40%
  4. Run Prep cycle
  5. 12-hour controlled soak
  6. Run CVS/FTP test with oil catalyst (1)
  7. Run Prep cycle
  8. 12-hour controlled soak
  9. Run CVS/FTP test with oil catalyst (2)

Driving Conditions Tested

Testing included maintaining speeds of 55+ miles per hour for set periods of time, coasting, and acceleration similar to passing at speeds above 45+ miles per hour.
