STRONG PARTNERS. TOUGH TRUCKS2011 EPA Tier 4 Interim & EU Stage IIIB Emissions RegulationsFor Engine Power Outputs over 174 hp (130 kW)Tier 4 Interim / Stage IIIB Emissions Regulations1. What is the Tier 4 Interim and Stage IIIB emissions standard in 2011?Tier 4 Interim is the U.S. Environmental Protection Agency (EPA) emissions regulations for offhighwaydiesel engines in North America. Stage IIIB is the equivalent emissions regulations forthe European Union (EU) member states. In terms of effectivity dates and emissions levels, theEPA and EU are closely aligned.The regulations commence in January 2011 across the 174 to 751 hp (130-560 kW) powercategory, requiring diesel engines to reduce PM exhaust emissions by 90% and NOx exhaustemissions by 45% compared with the current Tier 3 and Stage IIIA emissions standards.The emissions standards for this power category are: 2.0g/kW-hr Oxides of Nitrogen (NOx) and0.02 g/kW-hr Particulate Matter (PM).2. What is the Tier 4 Final and Stage IV emissions standard in 2014?Beginning in 2014, EPA Tier 4 Final and EU Stage IV will require another major emissionsreduction for the industry. Off-highway diesel engines from 174 to 751 hp must reduce NOxemissions by a further 45% compared to the 2011 level. By 2014, both NOx and PM exhaustemissions will be reduced by 90% compared with current Tier 3 and Stage IIIA levels.The emissionsstandards for thispower category are:0.4g/kW-hr Oxidesof Nitrogen (NOx)and 0.02 g/kW-hrParticulate Matter(PM). These extremelylow levels can bedescribed as ‘nearzero’ emissions levels.4


3. What are Oxides of Nitrogen (NOx) and Particulate Matter (PM)?Oxides of Nitrogen are a regulated diesel emission which is a collection term for gaseousemissions composed of nitrogen and oxygen. Particulate Matter is a regulated diesel emissioncomposed primarily of carbon soot and other combustion by-products.4. Is CO 2also a part of the Tier 4 Interim or Stage IIIB standard?No, CO 2is not regulated in the Tier 4 Interim or Stage IIIB regulations. Governments andnational bodies can force end users to use products with lower CO 2emissions. CO 2emissionscan only be reduced by lowering the fuel consumption.Many Hyster Big Trucks with Tier 4 Interim / Stage IIIB compliant engines will benefit from areduction in fuel consumption of in the region of 15%, when compared to their predecessors,and will experience no change in performance.5. When will engines below 174 hp need to meet the low emissions regulations?For engines within the 75 hp to 173 hp (56 – 129 kW) power category, Tier 4 Interim and StageIIIB regulations will commence in January 2012. The Tier 4 Final and Stage IV regulations willbe applied in January 2015. Emissions levels are less severe for this power category at Tier 4Interim and Stage IIIB, enabling more simplified after treatment.5


STRONG PARTNERS. TOUGH TRUCKS2011 EPA Tier 4 Interim & EU Stage IIIB Emissions RegulationsFor Engine Power Outputs over 174 hp (130 kW)6. Will all equipment supplied into the affected market areas be equipped with aStage IIIB/Tier 4 Interim engine from January 2011?No, both EU and EPA permit a certain degree of flexibility in its enforcement. Hyster can offereither a Stage IIIA / Tier 3 or Stage IIIB / Tier 4 Interim equivalent in 2011. However localenvironmental regulations can demand a Stage IIIB / Tier 4 Interim engine.7. Can I export Stage IIIB / Tier 4 Interim trucks between the EU and US/Canada?No, although the emissions requirements are the same, it’s not permitted to import anEU Stage IIIB-compliant engine to the US and vice versa. EU and EPA engines have adifferent certification.Technology8. Which technologies are available to achieve Tier 4 Interim / Stage IIIB emissionstandards?There are two approaches for meeting the Tier 4 Interim emissions standard.A) Selective Catalytic Reduction (SCR) introduces a urea solution known as dieselexhaust fluid (DEF) to neutralize nitrogen oxides (NOx) in the exhaust stream. DEFand the exhaust gasses are mixed in a catalytic converter which reduces the NOx toNitrogen and Oxygen elements. DEF is commercially known as “AdBlue” in Europe and is asolution of 32.5% urea and purified water. The engine is optimized on low PM emission.B) Advanced Exhaust Gas Recirculation (EGR) combines today’s approach withhigh-pressure common-rail fuel injection and electronically controlled air and fuelmanagement. Particulates are collected in a Diesel Particulate Filter, the particulateswill be oxidized by passive and or active regeneration. The engine is optimized on lowNOx emission.6


9. How will Hyster meet the Tier 4 Interim /Stage IIIB emissions standards in 2011?Hyster will meet the 2011 low emissions standardswith Cummins QSB and QSL engines, an integratedCummins Particulate Filter exhaust after treatmentsystem and a cooled exhaust gas recirculation (EGR)system incorporated into the engine.The cooled EGR system enables clean combustion with NOx reduced by 45% comparedto Tier 3 / Stage IIIA, while the Cummins Particulate Filter exhaust after treatment systemreduces PM by over 90% from engine exhaust.10. Is Cummins the right engine manufacturer for Tier 4 Interim / Stage IIIB?Yes. Cummins designs and manufactures the Cummins Particulate Filter as an integratedsystem with the engine. Meeting Tier 4 Interim and Stage IIIB demands new levels of systemintegration in order to achieve very low emissions while improving performance.Cummins has access to all the key enabling technologies within their design and manufacturingresources, from after treatment, fuel systems, filters and electronic control to turbo charging.This forms the basis of our ‘Right Technology’ approach to Tier 4 Interim / Stage IIIB. ThereforeCummins is the right partner for Hyster Big Trucks to meet the new emission standards.11. Has the Particulate Filter after treatment been used before?This technology is new to the off-highway equipment industry – but it is not new. Cumminsintroduced on-highway engines in 2007 certified to EPA standards in North America using bothcooled EGR and the Cummins Particulate Filter. The experience of using EGR extends backto 2002.Cummins’ capability with this technology is unmatched in the industry, and is reflected in theseproduction figures as of the start of 2010:EGR engines produced: 750,000Particulate filter after treatment systems produced: 450,0007


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


STRONG PARTNERS. TOUGH TRUCKS2011 EPA Tier 4 Interim & EU Stage IIIB Emissions RegulationsFor Engine Power Outputs over 174 hp (130 kW)Systems and New PartsEGR Cooled and VGT18. How does cooled EGR reduce NOx emissions?Cummins utilizes cooled EGR to effectively control NOx emissions. Cooled EGR works byre-circulating a varying proportion of the exhaust gas back to the cylinder. This reduces theoxygen content to a lower combustion temperature resulting in a reduction of NOx formation.The exhaust gas is cooled as it flows through an EGR cooler, and then is mixed with thecompressed fresh air from the turbocharger before entering the intake manifold. EGR is introducedto reduce the amount of in-cylinder oxygen available for combustion while maintaining the sameamount of flow through the engine. Exhaust gases present during the start of combustion are verystable and have a very slow reaction rate. They absorb heat during combustion, resulting in lowerin-cylinder peak flame temperatures, and therefore, lower NOx emissions.19. What are the keycomponents of the EGRSystem?The key components ofthe Cummins cooled EGRsystem are: EGR Valve, EGRcooler and Variable GeometryTurbocharger (VGT). Aschematic of the system isshown to the right:10


20. How does the Variable Geometry Turbocharger improve performance?The Cummins Variable Geometry Turbocharger has a patented one-piece sliding nozzle designthat provides exact boost across the operating range. The sliding nozzle varies the exhaust gasflow into the turbine wheel to provide rapid boost at low engine rpm and then maintain highboost at higher rpm.The VGT design combines the benefit of both a small and large turbocharger in a singleunit, enabling Cummins Tier 4 Interim / Stage IIIB to achieve significantly improved responsecompared to a Tier 3 / Stage IIIA engine demonstrated in customer field tests.Manufactured by Cummins Turbo Technologies, the Variable Geometry Turbocharger is akey technology asset in not only meeting emissions but increasing engine performance andimproving fuel efficiency. Introduced with Cummins on-highway EGR engines in 2002, total VGTproduction is approaching three million units, demonstrating outstanding in-service reliability.Diesel Particulate Filter After Treatment21. How does the Diesel Particulate Filter remove PM?The Cummins Particulate Filter replaces the Tier 3 / Stage IIIA muffler and provides equivalentor better sound reduction. The Particulate Filter consists of four sections: an inlet, a DieselOxidation Catalyst (DOC), a Diesel Particulate Filter (DPF) and an outlet.Exhaust flows out of the engine and into the Particulate Filter. It passes through the DOC andthen into the DPF where PM is collected on the walls of the DPF. The carbon collected is thenoxidized to remove it from the DPF. This is known as regeneration.When operating conditions maintain sufficient exhaust temperatures, the DPF is continuallyself-regenerating. This is known as passive regeneration and results in clean exhaust out of thetailpipe. On very infrequent occasions, an active self-regeneration is required to remove abuild-up of PM in the DPF, due to insufficient exhaust temperatures.11


25. Does the Particulate Filter get hotter than a typical muffler during activeregeneration?Active self-regeneration takes place typically less than 1% of equipment operating time. The skintemperature of the Particulate Filter, which is double-thermally insulated, is actually lower thanthe muffler skin temperature of today’s Tier 3 / Stage IIIA powered machines.Engine Cooling26. Why is cooling on demand required on Tier 4 Interim / Stage IIIB?With the introduction of Tier 4 Interim / Stage IIIB the engine cooling demands have beenincreased - the EGR cooler introduces extra heat into the engine coolant. Cooling on-demandhas been developed by Hyster to limit the power consumption of the increased cooling capacity.A controller controls the fan speed based on system temperatures of the engine, hydraulics andtransmission. With cooling on-demand all truck systems will be controlled to keep them in themost efficient temperature range.Cooling on demand results in fuel savings and reduced cooling fan noise.Filtration Enhancements27. What new filtration systems are used on Tier 4 Interim / Stage IIIB trucks?Engine filtration enhancements include a new Cummins Direct Flow air cleaner and crankcaseventilation system with a highly-efficient coalescing filter.28. How is the Cummins Direct Flow air cleaner differentfrom other air-intake filters?The new Cummins Direct Flow air cleaner was specificallydeveloped for Tier 4 Interim / Stage IIIB to provide moreperformance in less space. The rectangular, low profiledesign can reduce space by up to 50% compared with typicalcylindrical filters used for Tier 3 / Stage IIIA. Air flow to the engine isimproved and the highest levels of protection are assured with virtually 100%efficiency over the filter life.13


STRONG PARTNERS. TOUGH TRUCKS2011 EPA Tier 4 Interim & EU Stage IIIB Emissions RegulationsFor Engine Power Outputs over 174 hp (130 kW)29. Can Direct Flow extend filter change intervals?The increased air flow efficiency of the Direct Flow air cleaner offers operators the opportunity toextend air filter element service internals and potentially lower air filter costs.30. How does the crankcase ventilation filter improve the engine?Tier 4 Interim / Stage IIIB requires that crankcase emissions, also known as blowby gasses, beeliminated. To achieve this, Cummins engines incorporate a highly efficient coalescing filter. Thefilter returns the oil to the crankcase and provides the added benefit of removing oil mist and tinyoil droplets, ensuring that the engine and powertrain remain cleaner than at Tier 3 / Stage IIIA.The crankcase filter requires a simple filter element change at 2,500 hour intervals.Electronic Enhancements31. How does the Electronic Control Module (ECM) differ from Tier 3?The Tier 4 Interim / Stage IIIB engine management system has been significantly upgraded. Thelatest electronic control module provides three times faster processing power and double thememory capacity of the Tier 3 / Stage IIIA module.Cummins has a unique advantage in that it designs the core programs and algorithmsneeded to precisely control the engine from air-intake to exhaust after treatment as a singleintegrated system.32. Does Cummins use the same electronic system for all engines?Yes. Cummins latest generation CM2250 electronic control module will be incorporated on allTier 4 Interim / Stage IIIB engines to ensure electronic commonality across equipment ranges.14


33. Will electronic diagnostic tools change for Tier 4 Interim / Stage IIIB?Cummins popular and easy-to-use electronic diagnostic tools such as InSite software andQuickCheck handheld device are already upgraded and available for use with Tier 4 Interim /Stage IIIB engines and the Cummins Particulate Filter after treatment.Service Requirements34. Will Tier 4 Interim / Stage IIIB equipment uptime remain the same as Tier 3 /Stage IIIA?Yes. Field test programs has demonstrated that Tier 4 Interim / Stage IIIB engines are able toachieve the same very high level of uptime as equipment powered with current Tier 3 / StageIIIA engines.35. What service does the Cummins Particulate Filter require?The Cummins Particulate Filter is service-free up to 5,000 hours. At that point, ash cleaning isrequired. The EPA has set minimum ash cleaning intervals of 4,500 hours for engines above174 hp (130 kW). Cummins expects to reach 5,000 hours before ash cleaning is required.36. What causes ash in the Particulate Filter?Ash is incombustible material derived from the additive pack in the lube oil. All engines consume asmall amount of oil as part of their normal operation. The oil is burned in the combustion chamberalong with the fuel, and the resulting small amount of residual ash from the oil is trapped in the filtersection of the after treatment system. During filter regeneration, the PM is oxidized and removedfrom the filter. However, ash from the lube oil cannot be oxidized and remains in the filter.37. How is the Diesel Particulate Filter serviced?The Diesel Particulate Filter must be removed and cleaned by a Cummins-approved cleaningmethod and authorized technician. The ash cleaning process typically takes 30 minutes, plusthe time to remove the Cummins Particulate Filter from the equipment. Hyster will provide aDiesel Particulate Filter exchange program.15


STRONG PARTNERS. TOUGH TRUCKS2011 EPA Tier 4 Interim & EU Stage IIIB Emissions RegulationsFor Engine Power Outputs over 174 hp (130 kW)38. What is the life of the Diesel Particulate Filter?The Diesel Particulate Filter is designed to last the life of the engine. The after treatment isspecially strengthened against high levels of vibration and shock loading.39. Is low ash lube oil required for Tier 4 Interim / Stage IIIB?Yes. To maintain regulated ash cleaning intervals it is strongly recommended to use API CJ-4low ash lube oil in North America and equivalent ACEA-E9 lube oil in the EU.Fuel Requirements40. Is ULSD fuel legally required for Tier 4 Interim engines?Yes. In North America, Ultra Low Sulphur Diesel (ULSD) is legally required for Tier 4 Interimengines. The ULSD must contain 15 parts-per-millions (ppm) or less sulphur content.41. Does the European Union have the same fuel requirements forStage IIIB engines?In the European Union, Ultra Low Sulphur Diesel (ULSD) must legally be 10ppm at the point ofmanufacture and is expected to be 15ppm at the point of use.16


42. Will ULSD be available outside of North America and the European Union?Availability of ULSD is very limited outside of North America and the European Union – so it iscritical to not operate an engine requiring ULSD in a country without available ULSD supply.Using high sulphur content fuel will damage the engine and after treatment system.43. Could today’s fuel be used in Tier 4 Interim / Stage IIIB engines?Tier 4 Interim engines must use ULSD. It is not possible to comply with the legally required PMemissions standard with today’s off-highway fuel which has a higher sulphur content.44. What happens if higher sulphur fuel is inadvertently used?A one time inadvertent tank of diesel fuel with greater than 15ppm sulphur content will notdamage the engine and after treatment system. The system will clean itself out when ULSD isre-introduced.However, continued improper fuel use of sulphur levels greater than 15ppm with Cummins Tier4 Interim / Stage IIIB engines can permanently damage the engine and after treatment systemswithin a short period of time. This damage could possibly cause the engine to be inoperable andcause unplanned downtime and expenses.45. Is the engine warranty affected if ULSD is not used?Yes. Improper fuel use of sulphur levels greater than 15ppm with Cummins Tier 4 / Stage IIIBengines can result in denial of warranty coverage.46. Can ULSD be used in Tier 3 / Stage IIIA or other engines?Yes. Current engines will work fine on ULSD. It is backwards compatible.17


STRONG PARTNERS. TOUGH TRUCKS2011 EPA Tier 4 Interim & EU Stage IIIB Emissions RegulationsFor Engine Power Outputs over 174 hp (130 kW)47. When will ULSD fuel be available?ULSD is available today. ULSD was widely introduced in North America in 2006 and morerecently in the European Union for emission compliant on-highway engines. Cumminsanticipates that ULSD for off-highway applications will be widely available for Tier 4 Interim /Stage IIIB engines in 2011. Both the EPA and EU have a schedule in place with fuel producersand distributors to make ULSD available.48. Can biodiesel fuel be used with Cummins Tier 4 Interim / StageIIIB engines?Cummins Tier 4 Interim / Stage IIIB engines are compatible with Biodieselblends up to B20.Warranty49. Does Tier 4 Interim / Stage IIIB technology change the current warrantycoverage on engines?Current engine warranty will become a broader engine and system warranty for Tier 4 Interim /Stage IIIB by incorporating the Diesel Particulate Filter after treatment and Direct Flow air cleanerhousing. Warranty hours, terms and conditions remain unchanged for Tier 4 Interim / Stage IIIB.50. What happens if Tier 4 Interim / Stage IIIB engines are operated outside of theirintended emissions region?Tier 4 Interim / Stage IIIB engines and after treatment which are exported and operated outsideof their intended emissions region will not carry a warranty. The very low emissions levels forTier 4 Interim / Stage IIIB require specific technology that is not appropriate for regions with lessrigorous standards.Since emissions standards vary across the world, Hyster designs its products to meet thestandards of an individual country and/or emissions region. Dealers and customers shouldcarefully select the correct engine to meet the emissions requirements of their respective country.18


Field Test Experience51. What Tier 4 Interim / Stage IIIB field test experience does Cummins / Hyster have?The first of the Cummins Tier 4 Interim / Stage IIIB field test engines started running in the fieldin June 2008. Tier 4 Interim / Stage IIIB represents the most extensive development, conceptinstallation and field test program that Cummins has ever undertaken with off-highway engines.Hyster has many Tier 4 Interim / Stage IIIB forklift trucks running in the field to prove reliabilityand to demonstrate low fuel consumption in daily application usage.52. How are the Tier 4 Interim / Stage IIIB engines performing?The message from the operators is that the Cummins Tier 4 Interim / Stage IIIB solution isdependable, reduces their operating costs and improves the performance of their machines.The field test program surpassed 20,000 hours of operation in January 2010 and continuesto rapidly accelerate the total number of overall hours. The field test machines are remotelymonitored over the cellular network which enables Cummins engineers to quickly fine tuneengine calibrations to further enhance Tier 4 Interim / Stage IIIB equipment productivity.53. What is the opinion of the Tier 4 Interim / Stage IIIB field test operators?Cummins field test installations are receiving excellence testimonial comments from equipmentowners and operators who prefer the cleaner, more fuel efficient and responsive Tier 4 Interim/ Stage IIIB engines compared with Tier 3 / Stage IIIA powered equipment. Some of thesecomments are shown below:“...we prefer to use the Tier 4 because it is quieter, much more response, no downtime,no problems...”“...our fuel efficiency has improved by at least 5% with this machine...”“...it’s amazingly better, yes, a lot stronger, a lot faster, a lot quicker, everything...”“...Tier 3 was nice - and now this one is a whole lot better engine...”.“...the fact that you don’t have to do anything to make the Tier 4 system function is thebest integration...”19
