  12. Integrating Critical Subsystems Filtration and Diesel Exhaust Fluid Electronic Controls Combustion Technology Aftertreatment System Fuel Systems Turbochargers

  13. Cummins 2013 Engines Same NOx and PM emissions regulations as 2010 • 0.2g NOx and 0.01g PM Same base engine and aftertreament as 2010 - 2012 • 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

  14. New ECM

  15. Pictures of Air Intake and ECM New Air Intake Throttle

  16. 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

  17. Malfunction Indicator Lamp (MIL) Located on the dash of the vehicle It illuminates to indicate an OBD related fault Simplifies diagnostic and repair procedures for the technician and servicing location

  18. On-Board Diagnostics (OBD) Aftertreatment System Monitoring ECM Monitoring Engine System Monitoring Service Tools MIL

  19. 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

  20. 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

  21. 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

  22. CO2 and Fuel Efficiency NOx, PM Evolution of Technology Selective Catalytic Reduction Over 90% Reduction of Nitrogen Oxides and Particulate Matter Diesel Particulate Filter Cooled Exhaust Gas Recirculation Electronic Fuel Systems Aftercooling 1990 2000 2010 2020

  23. Future Regulations 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)

  24. 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)

  25. Future Development Vehicle Manufacturer Integration • All subsystems Cooling System Improvements Fuel Economy • GHG Compliance in 2014 and 2017 Aftertreatment • Improved Efficiency Future Maintenance Requirements • None at this time

  27. Long Beach TransitEmbracing CNG APTA Webinar January 24, 2013

  28. Agenda • Background • Why CNG? • Procurement • CNG Station / Site Modification • CNG Buses • Training • SCRTTC

  29. LBT Mission • Long Beach Transit is in business to provide public transportation services that enhance and improve the quality of life for the people in our community. • We serve Long Beach, along with 11 other cities – 98 square miles • 29 million ridership

  30. Quality of Life • Sustainability – drives our decision to clean up emissions on our vehicles • Diesel Coaches – all purchases prior to 2003 • Installed particulate traps on diesel buses in 2001 • Early adopter of ultra-low sulfur diesel • 2003 made a decision to go gas hybrid • Procured 89 gasoline hybrid electric buses to date • Staff and operations vehicles are actively being replaced with hybrids • 2010 – completed alternative fuel study with WVU – essence maintain diverse fuel choice

  31. CNG Plans • LBT planned on CNG for 2015 • CNG economically good vs gas hybrid • Lower Operating Costs w/ tax credit • Infrastructure costs - break even point at one property for 40 coaches & other 70 • ISE bankruptcy in late 2010 • CNG purchases moved to 2012 • Must build a CNG station within one year • Modify both facilities to accommodate CNG • Procure 64 buses with CNG engines

  32. Fleet Makeup • Revenue Fleet • 171 – 40’ New Flyer buses (89 gasoline electric hybrid) • 13 – 60’ New Flyer articulated buses • 64 CNG – 40’ Gillig BRT • 10 Electric buses in 2014 • Other Services • 17 Dial-A-Lift vans (Paratransit) • 4 boats (2 AquaBus & 2 AquaLink) • 1 Charter (Prevost) • Support Vehicles • 31 service veh for supervisor, staff & operators • 25 maintenance service vehicles • TOTAL of 326 VEHICLES • 4 Propulsion Systems (Diesel, Gasoline Hybrid, CNG & All-Electric)

  33. CNG Station, Infrastructure Modification & Buses Project Plan

  34. CNG Project Goals Provide CNG fueling station able to fuel 77 – 95 coaches Upgrade infrastructure to accommodate repairs in entire shop & fuel island Prepare utilities for CNG (gas & electricity) Buy 64 CNG buses Get LBT transitioned to CNG Environmental understanding - ESMS

  35. Project Constraints • Goal 1 year – anticipating delivery of new CNG coaches • Budget for station was tight – need to keep within $6.2 million • Heavy workload on facility team • Limited Staff Experience for CNG • Limited Staff Time for Project • Need City approval & cooperation (including LB Fire Department) – avoid EIR if at all possible

  36. CNG Station Contract Awarded • 4 qualified proposals received ranging from $4.5 to $6.18 million • Contract Awarded to Amtek Construction, Lowest bid at $4.5 million • Proposed Angi Energy Systems • Compressors – five (500-scfm/250-hp) • Gas Dryer - accommodate 3000 scfm • Two (2) Buffer Storage paks • 2 CNG fast-fill Dispensers & 1 slow • Modify all of LJ facility (12 bays) & 3 bays at AA facility

  37. Maintenance Impact Station • Need Daily inspections & scheduled PM’s • LBT chose to contract out • Amtek – 1 year maintenance agreement • Clean Energy – doing daily & oversight • Going out to bid to award long-term contract, still need some facility training • Need to train all employees on Safety & Maintenance on fueling

  38. CNG Coach Purchases • Piggy Back - contract with Gillig for 64 coaches (after full evaluation) • Cummins Engine – ISL G - 280 • ZF Transmission – Eco Life 6AP 1400B • CNG Tanks & Fueling System • Gas Detection w/ Fire suppression

  39. Maintenance Impact Buses • Fluids resulting from CNG / ISLG: • A low ash engine oil • A premium long life coolant • Material Review & order • Preventative Maintenance Impact • Gas detectors & system health • Inspection of CNG components, valves, piping, leak detection, filter draining & replace • CNG tank inspection at 3 yrs or 36,000 miles by a “certified” inspector, required training and CSA test for cert. LBT will do once per year.

  40. CNG Training Project Plan

  41. Training • Training Needs • CNG Station / Site Safety • CNG Tanks / Safety • CNG Engine • No one Stop Shopping • LBT staff looked at all options • Amtek / ANGI • Natl Gas Vehicle Institute (NGVI) • Gillig, Cummins, Amerex • SCRTTC

  42. CNG Site Awareness & Safety • Facility - ANGI (Fuel Station) • Utility - CNG Safety & Fueling • Maintenance - CNG Safety / Methane detection • Staff – CNG Awareness 612 Total Hours
