4 Emissions information The ultimate in performance, fuel economy, and emissions compliance is available with John Deere engines. To meet emissions regulations, John Deere worked closely with equipment manufacturers to identify engine technologies that best suited their needs. John Deere engines comply with nonroad emissions regulations for the U.S. Environmental Protection Agency (EPA), the European Union (EU), and the California Air Resources Board (CARB). 6 7

5 EPA nonroad emissions regulations new source performance standard (NSPS) kw hp EU nonroad emissions regulations constant speed kw hp Not regulated in EU Not regulated in EU Option * 4.7 Option * Not regulated in EU *In the 50 to 75 horsepower category there are two options. Option 1 requires a reduced PM level (.30 vs.40) but allows Final Tier 4 to be delayed one year (2013). NOTE: The vertical dashed lines separating the years show when the seven-year life of the Tier 2/3 Equipment Flexibility Provision ends and engines can no longer be placed in vehicle production. The new source performance standard (NSPS) required most stationary engines to be Tier 1 compatible on 01 April 2006 and meet current nonroad mobile standards after 01 January EPA: Environmental Protection Agency EU: European Union Legend EPA Tier 1 Tier 2 Tier 3 Interim Tier 4 Final Tier 4 EU Stage I Stage II Stage III A Stage III B Stage IV Examples NOx NMHC PM , the maximum amount of nitrogen oxides (NOx) allowed in g/kwh. 0.19, the maximum amount of nonmethane hydrocarbons (NMHC) allowed in g/kwh , the maximum amount of particulate matter (PM) allowed in g/kwh. NMHC + NOx PM , the maximum amount of NMHC + NOx allowed in g/kwh. 0.80, the maximum amount of PM allowed in g/kwh. European Union directive 97/68/EC requires constant speed engines, such as mobile gen-sets, meet Stage II emissions levels on 01 January The directive also requires constant speed engines meet Stage III A emissions levels beginning 01 January

6 Nonstop power wherever you need it John Deere generator drive engines keep the power on through the most powerful storms and in the most remote locations on earth. Our engines meet emissions regulations while delivering quick-starting, cleanrunning, and fuel-efficient performance. Plus, they are available with more power in a compact size for installation flexibility. Power at a moment s notice John Deere-powered standby generator sets protect critical applications, ensure uninterrupted productivity, and offer peace of mind. The EPA allows emergency standby applications to use current Tier 3 products that do not require aftertreatment. The European Union (EU) does not regulate emergency standby applications. Power in remote locations John Deere generator drive engines provide prime power for pumping stations, peak shaving, distributed power, mining, and other remote applications. Starting in 2011, prime power applications are required to meet Interim Tier 4 emissions regulations in North America and Stage III A in Europe.

7 PowerTech PWX 4.5L engines EPA Interim Tier 4 PowerTech PWX Interim Tier 4 technology Exhaust Out Fresh Air Filter WGT DOC Exhaust EGR Cooler Exhaust Throttle Valve Compressed Air From Turbocharger EGR Valve Air-to-air Cooler Wastegated turbocharger Wastegated turbochargers are designed to develop more air flow at lower engine speeds to improve low speed torque. The wastegate control device bleeds off a portion of the exhaust flow at higher engine speeds. Wastegated turbos deliver improved transient response and higher peak torque without compromising engine envelope size. They also provide the lowest installed cost across a given power range. Cooled exhaust gas recirculation (EGR) EGR cools and mixes measured amounts of cooled exhaust gas with incoming fresh air to lower peak combustion temperatures, thereby reducing NOx. Exhaust filters These engines utilize an exhaust filter that contains a diesel oxidation catalyst (DOC) and a particulate filter. The DOC reacts with exhaust gases to reduce carbon monoxide, hydrocarbons, and some particulate matter (PM). The downstream filter traps and holds the remaining PM. Trapped particles are oxidized within the filter through a continuous cleaning process called passive regeneration. Regeneration occurs during normal operating conditions when heat from the exhaust stream and catalysts within the exhaust filter trigger the oxidation of the trapped PM

8 High-pressure common-rail (HPCR) and engine control unit (ECU) The HPCR fuel system provides variable common-rail pressure and higher injection pressures up to 1,975 bar (29,000 psi). It also controls fuel injection timing and provides precise control for the start, duration, and end of injection. 4-valve cylinder head The 4-valve cylinder head provides excellent airflow by utilizing a cross-flow design. Air-to-air aftercooled This is the most efficient method of cooling intake air to help reduce engine emissions. It enables an engine to meet emissions regulations with better fuel economy and the lowest installed costs. Compact size Simplifies installation Mounting points are the same as previous models John Deere electronic engine controls Faster engine control unit (ECU) manages both the engine and the exhaust filter Full authority electronic controls Four times the memory, twice the RAM, and double the processing speed The input/output capability has increased 40% Additional features Glow plugs 500-hour oil change Self-adjusting poly-vee fan drive Variable-speed fan drive increases fuel economy and decreases noise levels R.H. and L.H. engine-mounted final fuel filters Optional low-pressure fuel system with electrical transfer pump and auto-prime feature 14 15

9 PowerTech PVX 4.5L, 6.8L, and 9.0L engines EPA Interim Tier 4 PowerTech PVX Interim Tier 4 technology Exhaust Out Fresh Air DPF VGT DOC Injector* Exhaust EGR Valve Intake Throttle Valve Exhaust filters These engines utilize a catalyzed exhaust filter that contains a diesel oxidation catalyst (DOC) and a diesel particulate filter (DPF). The DOC reacts with exhaust gases to reduce carbon monoxide, hydrocarbons, and some particulate matter (PM). The downstream DPF traps and holds the remaining PM. Trapped particles are oxidized within the DPF through a continuous cleaning process called passive regeneration. Passive regeneration occurs during normal operating conditions when heat from the exhaust stream and catalysts within the exhaust filter trigger the oxidation of the trapped PM. If passive regeneration cannot be achieved due to low temperature, load, or speed, then PM is removed using active regeneration an automatic cleaning process controlled by the exhaust temperature management system. Engines below 130 kw (174 hp) use an in-cylinder dosing system for active regeneration, while larger engines use an external dosing system. EGR Cooler Compressed Air From Turbocharger Air-to-air Cooler High-pressure common-rail (HPCR) and engine control unit (ECU) The HPCR fuel system provides variable common-rail pressure and higher injection pressures up to 1,975 bar (29,000 psi). It also controls fuel injection timing and provides precise control for the start, duration, and end of injection. * For engines 130 kw (174 hp) and greater. Variable geometry turbocharger (VGT) Varies exhaust pressure based on load and speed to ensure proper EGR flow. The combination of the cooled EGR and VGT provide low-speed torque, quicker transient response, higher-peak torque, and world-class fuel economy. 4-valve cylinder head The 4-valve cylinder head provides excellent airflow by utilizing a cross-flow design (4.5L and 6.8L) and a U-flow design (9.0L). Cooled exhaust gas recirculation (EGR) EGR cools and mixes measured amounts of cooled exhaust gas with incoming fresh air to lower peak combustion temperatures, thereby reducing NOx

11 PowerTech PSX 6.8L, 9.0L, and 13.5L engines EPA Interim Tier 4 PowerTech PSX Interim Tier 4 technology Exhaust Out Fresh Air DPF VGT DOC Fixed Injector Exhaust EGR Valve Intake Throttle Valve Series turbochargers Fresh air is first drawn into the low-pressure turbocharger (fixed geometry) and compressed to a higher pressure. The compressed air is then drawn into the high-pressure turbocharger (VGT), where the air is further compressed. The high-pressure air is then routed through a charge air cooler and into the engine s intake manifold. By splitting the work between two turbochargers, both can operate at peak efficiency and at slower rotating speeds lowering stress on turbocharger components and improving reliability. Series turbocharging delivers more boost pressure than single turbocharger configurations, which results in higher power density, improved low-speed torque, and improved high altitude operation. Cooled exhaust gas recirculation (EGR) EGR cools and mixes measured amounts of cooled exhaust gas with incoming fresh air to lower peak combustion temperatures, thereby reducing NOx. EGR Cooler Compressed Air From Turbochargers Air-to-air Cooler Exhaust filters These engines utilize a catalyzed exhaust filter that contains a diesel oxidation catalyst (DOC) and a diesel particulate filter (DPF).

25 Definitions Prime power is the nominal power an engine is capable of delivering with a variable load for an unlimited number of hours per year. This rating conforms to ISO 3046 and SAE J1995. Standby power as defined in ISO is the maximum engine power available at varying load factors for up to 200 hours per year. This rating conforms to ISO 3046 and SAE J1995. The calculated generator set rating range for standby applications is based on minimum engine power (nominal -5 percent) to provide 100 percent meet-or-exceed performance for assembled standby generator sets
