STRONG PARTNERS. TOUGH TRUCKS2011 EPA Tier 4 Interim & EU Stage IIIB Emissions RegulationsFor Engine Power Outputs over 174 hp (130 kW)12. Why is the Hyster/Cummins Tier 4 Interim / Stage IIIB approach better than others?We believe the Cummins has significant advantages over other engine manufacturers. Cumminsdesigns, manufactures and integrates the complete Tier 4 Interim / Stage IIIB package from airintaketo exhaust after treatment. Only Cummins has all the key enabling technologies in-houseand can therefore realize more effective integration with packaging and performance advantages.13. Will Tier 4 Interim / Stage IIIB engine performance be the same asTier 3 / Stage IIIA?It will be better. Tier 4 Interim / Stage IIIB equipment productivity is also enhanced with fasterengine response.Operators will also notice that Hyster Tier 4 Interim / Stage IIIB trucks work cleaner and quieterthan before. While CO 2emissions are not regulated by the EPA or EU, levels will be reduced.Furthermore, in addition to the Cummins technologies applied to reduce fuel consumption, Hysterhas introduced cooling on demand and alternate engine idle speed, which contribute to additionalfuel savings, which results in a total reduction in fuel consumption of in the region of 15%.14. How will equipment operating costs be impacted by Tier 4 Interim / Stage IIIB?Overall operating costs for Hyster trucks will be lower at Tier 4 Interim / Stage IIIB comparedto Tier 3 / Stage IIIA. The Cummins Tier 4 Interim / Stage IIIB engine offers lower fuelconsumption, and depending on duty cycle and application, Hyster Tier 4 Interim / Stage IIIBtrucks can achieve fuel consumption reductions of in the region of 15% by applying coolingon demand technology and optimizing engine performance characteristics. The improved fuelconsumption will more than offset the marginal cost increase associated with using ULSD fuel,low ash lube oil and particulate filter cleaning requirements at 5,000 hours.15. How will Tier 4 Interim / Stage IIIB impact the cost of equipment?Achieving very low levels of emissions for Tier 4 Interim / Stage IIIB requires a major investmentin engine technology and involves the addition of new systems such as Particulate Filter aftertreatment. The cost of the equipment will therefore reflect the incorporation of a Tier 4 Interim /Stage IIIB technology system and more advanced cooling packages.8
