  1. Heavy-Duty Diesel Inspection & Maintenance Development Section (HDD I/M DS)Mobile Source Operations DivisionDon ChernichFebruary 23, 2012

  2. Not a typical MSOD section… • Staff located in Sacramento, Depot Park, and El Monte. • The section has 11 staff comprised of Engineers, Specialists, Field Representatives and Students. • The section has two main vocations: • - The Periodic Smoke Inspection Program (PSIP) • - The Depot Park HD Test Facility

  3. Periodic Smoke Inspection Program (PSIP) • Requires California based fleets w. two or more trucks to perform annual smoke inspections of their heavy-duty trucks. • Smoke tests conform to SAE J1667 Snap Acceleration test procedure. • ARB Field Representatives visit fleets and audit their smoke test records. • Non-compliant fleets are referred to Enforcement Division for follow-up. Heidi Kroll & Chris Milton Performing PSIP fleet audits.

  4. Why do these inspections? • Two percent of the on-road trucks account for 30% of the NOx and 65% of the PM10. • Diesel PM is a Toxic Air Contaminate and contributes to premature deaths, cancer, and respiratory disease. Diesel soot particle • The PSIP and the Heavy-Duty Vehicle Inspection Program achieves a reduction of 23 TPD of ROG, NOx and PM.

  5. Depot Park Facility • Originally located in Stockton, CA moved to Sacramento’s Depot Park in October 2010. • Three types of projects are carried out at Depot Park: MSOD’s grey KW leaving Depot Park • In-use testing (PEMS, Not-to-Exceed) • Research/rule development programs (LCFS) • Confirmatory Evaluations (NO/NO2 ratio, Diesel Reflash effectiveness, etc.)

  6. PEMS testing Placerville PEMS Route • Allows for second-by-second measurement of emissions during normal operation. • Test routes can be selected to match desired operating conditions, such as: speed, load, and temperature. • Typical projects are in-use surveillance, inventory development, and systems operation verifications. NTE Evaluation

  7. Portable Emissions Measurement System (PEMS) Exh. Flow Meter PEMS unit Ballast weight Vehicle Interface

  8. Other support activities… Field investigation Fuels evaluation(Yosemite bus biodiesel study) Non-road vehicle testing (Napa wine train) Depot Park weather station • Check out the current weather at the Depot at: http://www.wunderground.com/cgi-bin/findweather/getForecast?query=95828&sp=KCASACRA63 Fuel calorimetry

  9. Future plans • Install transient HD chassis dynamometer. • Non-road equipment testing. • Clean room upgrades. • Expanded PM measurement capabilities (CPC, EEPS, etc.) • Engine dynamometer testing. • Expanded welding and fabrication capabilities. • Continued PEMS testing of diesel and gas powered vehicles. • Field outreach, investigations, and surveys.

  10. Conclusion/Q&A • Thank you to the dedicated staff: SherwineAbellana, Mark Burnitzki, Ramon Cabrera, Tullie Flower, Robert Ianni, Mohan Krishnamurthy, Heidi Kroll, Christina Medina, Christopher Milton, RoelofRiemersma, and Wayne Sobieralski. • Questions
