Make Every School Bus Better. Thomas Bus Oct 4, 2011 Steve D Goss Sanjay Kumar Jim Lannan
Agenda • Update on successes • IC Bus ‘Fluid’ Economy Claims • Cummins Fuel Economy • How to sell Cummins
School Bus Industry Data • Industry data suggests a 5% gain in Cummins market share (50% to 55%) • Recently gained business with largest bus customer
IC Bus ‘Fluid’ Economy Claims • IC Bus published report of fuel economy testing stating ‘up to a 4.5%’ advantage vs Cummins • Cummins responded to claims outlining the points in question including: • Transmission shift calibration selections • Aftertreatment regeneration ‘Fluid Economy’ also ignores the price differential Avg. Diesel Price $3.80 Avg. Bulk DEF Price $2.85
Transmission shift calibrations • IC Bus did not outline what shift calibrations were used during testing • Cummins testing validates that proper selection can result in significant fuel economy gains
Aftertreatment Regeneration • Typical regen cycle on MF 7 at approx. 135 miles • Same distance as test • More EGR = More Soot Generated = More Regens • Regenerations require the use of more fuel thus diminishing overall fuel economy
‘Fluid’ Economy • IC’s claims of ‘fluid’ economy inaccurately represent total cost of ownership • No mention of DEF consumption thus inability to analyze actual DEF usage for test • Differences in DEF and diesel fuel pricing vary significantly so need to be analyzed separately
Cummins Fuel Economy • ‘Others Test. We Deliver’ • Cummins and Thomas Bus both currently testing
ISB Fuel Economy Tops DTNA Testing Freightliner M2 106 with Cummins ISB (EPA 10) Vs. International Durastar 4300 with MaxxForce DT (EPA10) Result • 8.5% Better Fuel Economy • 2 Regens for ISB Vs 10 for MaxxForce DT in the 14 hour test period
In Cylinder NOx Control Challenges • Fuel economy significantly compromised • Increased risk of EGR condensation • Significant increase in heat rejection • Complex system integration • Driver satisfaction significantly compromised • Power density and torque limitations
In Cylinder NOx Control Challenges • 5-9% disadvantage • Combustion efficiency degradation: • Higher engine pumping losses • Increased intake & exhaust manifold pressures • Increased Particulate Filter regenerations Fuel Economy Significantly Compromised
In Cylinder NOx Control Challenges • Higher EGR flow produces excessive acidic condensation • Power cylinder corrosion • Rapid deterioration of lube oil • Reliability and durability compromised Increased Risk of EGR Condensation
In Cylinder NOx Control Challenges • 20% increase • Higher EGR flow: • Multiple EGR coolers on & off engine • Larger vehicle cooling package • Major redesign of radiator / Charge Air Cooler / Fan systems Significant Increase in Heat Rejection
In Cylinder NOx Control Challenges • Higher EGR flow • Air handling system • Vehicle cooling system Complex System Integration
In Cylinder NOx Control Challenges • Higher EGR Flow • Throttle Response Driver Satisfaction Significantly Compromised
In Cylinder NOx Control Challenges • Deterioration of 50 – 100 hp for same displacement • Higher EGR flow & EGR controls compromises engine performance Power Density and Torque Limitations
Bus Owners Have Two Choices for 2010 Clean Air DPF DOC Catalyst AMOX Cat DPF Doser Tank DOC Advanced EGR Intercooler Radiator Higher heat rejection: Larger Radiator Larger Charge air cooler EGR + SCR After-Treatment System Setup
Acidic pH The Facts about the Fluid – DEF Properties • DEF is safe to handle and store • Non-toxic • Non-polluting • Non-flammable • DEF freezes at 12° F (-11° C). However, frozen DEF does not impact start up and normal operation of the vehicle • When stored at extreme temperatures, neither DEF nor Urea become toxic • DEF is slightly alkaline with a pH of approximately 9 DEF
DEF - Myths & Facts • Navistar’s claim of ammonia level being close to 1000 ppm in a near empty DEF tank is a ‘stretch of imagination’ • DEF, when heated and maintained at a constant temperature 120 degrees Fahrenheit, will very slowly start to form small amounts of ammonia • It would take over two years at this constant temperature to convert DEF into levels of 1000 ppm of ammonia • Such a situation can be probably modeled in ‘laboratory setting’ but not in the real world
Cummins ISB6.7 vs Navistar MaxxForce 7Competitive Comparison
Designing For the School Bus Market • Reliability • Total cost of ownership • Low maintenance • Safe Operation • Sociability • Performance • Weight/space • Minimal driver training • Ease of operation • Information systems • Emissions compliance
ISB6.7 & ISC8.3 Features • Improved combustion system • Advanced VGT Turbocharger • Improved cooled-EGR subsystem/cooling circuit • Fully integrated electronic controls • New Cummins Aftertreatment System
ISB6.7 & ISC8.3 Customer Benefits • Best-in-Class Fuel Economy • Improved Reliability • Minimal Installation Impact • Stronger Performance • Increased Power Density
ISL G Product Features and Benefits • 8.9L Stoichiometric Cooled EGR engine with spark ignition • In production since mid-2007 • Low emissions • Diesel-‘like’ Performance, Reliability and Durability • Over 80% parts commonality with ISL9 • Compatible with CNG, LNG, or Biomethane (RNG)
Three Way Catalyst Aftertreatment Passive device Packaged as a muffler Maintenance-Free Stoichiometric Combustion Cooled EGR Same rated speed as ISL9 diesel 30% more torque at idle 5% better fuel economy 2010 ISL G Natural Gas
Integrating Critical Subsystems Filtration and Diesel Exhaust Fluid Electronic Controls Aftertreatment System Fuel Systems Turbochargers Combustion Technology
