  • New ECM
    • Integrated engine and aftertreatment controls
  • Intake air throttle for closed loop control (emissions)

OBD (On-Board Diagnostics) required – Diesel Only

  • New fault codes added to monitor emissions sytems

what is obd
What is OBD?

On-Board Diagnostics

  • Monitors nearly every component that can affect the emissions control system
  • Tests emissions-related components and systems to detect malfunctions
  • Similar to passenger car systems or Cummins Turbodiesel in RAM Pick-up / Chassis Cab which have OBD-II systems for many years

What Does OBD Mean For The Transit Industry?

Better monitoring of emissions systems

Increased accuracy in determining the root cause of emissions-related faults

Provides early warning of malfunctions

maintenance changes for 2013
Maintenance Changes for 2013

Fuel Filter change intervals (now at every oil change)

  • NanoNet fuel filter medium

Inspection intervals reduced

  • Radiator cap and SCA levels (20K to 15K miles)
  • Engine drive belts & tensioner (40K to 30K miles)
  • Air compressor discharge line (80K to 60K miles)

Aftertreatment servicing

  • Frequent regeneration faults

OEM Coolant Recover Tanks

  • Add Coolant to recovery tank, not top tank

OBD Fault Codes

  • New fault codes all added for emissions compliance
  • Cummins Insite / Generic Scan Tool
service tools
Service Tools
  • INSITE – Maintains ability to perform Cummins specific special tests whereas a generic scan tool cannot.
    • QSOL (QuickServeOnLine)
  • EDS – Next Generation Diagnostic Tool product offered through Cummins certified repair locations.
  • OBD connector style will be the same 9-pin connector used previously

2014 GHG Standards

  • CO2 Limits: Reduce by 3% in 2014 to 9% total in 2017 over a 2010 industry baseline
  • N2O and CH4 Limits (already met in 2010)

Cummins EPA 2013 compliant engines meet 2014 Greenhouse Gas and Fuel Efficiency standards

OEM (TVM) needs to use tires that are certified for compliance with GHG reduction (rolling resistance)

hybrid engine regulations
Hybrid Engine Regulations

Cummins will offer Hybrid engines that meet both EPA and ARB 2013 certification requirements.

Hybrid ratings will be distinct from conventional (non-Hybrid) ratings

Hybrid ratings with Engine Start Stop (ESS) capability will be distinct from non ESS Hybrid ratings and will be limited to one ISB Transit Bus rating. (First availability: July 2013)
