WWW.MARINELINK.COM 23John Deere Power Systems (JDPS) announced new Marine Tier 3 PowerTechTM 4.5L and 6.8L propulsion and generator-drive engines. John Deere will meet U.S. EPA Marine Tier 3 emissions regu- lations that began to take effect in 2009 based on cylinder displacement and power per displacement with a complete lineup of PowerTech 4.5L and 6.8L propulsion and generator-drive engines. They also will achieve compliance with IMO Tier II emis- sions regulations and EU 97/68/EC.New EPA Marine Tier 3 regulations will impact John Deere 4.5L and 6.8L engines beginning Janu- ary 1, 2013. Tier 3 regulations affecting John Deere 9.0L and 13.5L marine engines start in 2014. 4.5L ENGINES John Deere is adding two new 4.5L models to its lineup of Tier 3 marine engines: the PowerTech 4045TFM85 generator-drive engine and the Pow- erTech 4045AFM85 propulsion and generator- drive engine. The PowerTech 4045TFM85 gener- ator-drive engine is designed for quiet and smooth operation for genset applications. Features will in-clude a high-pressure common-rail fuel system, two valves per cylinder, and the choice of keel cooled or integrated heat exchanger options. The PowerTech 4045AFM85 will serve as a choice in the power range that was previously cov-ered for Tier 2 by the PowerTech 6.8L 6068TFM75 propulsion and PowerTech 6.8L 6068TFM76 gen- erator-drive engines. The PowerTech 4045AFM85 engine will feature a common-rail fuel system, four valves per cylinder, turbocharging and air-to- coolant aftercooling. It will be available with keel cooled or integrated heat exchanger options.Propulsion power ratings for this engine include:? PowerTech 4045AFM85 propulsion engine: 119 kW to 168 kW (160 hp to 225 hp) Generator-drive 4.5L engine prime power ratings include:? PowerTech 4045TFM85: 74 kW (99 hp) at 60 Hz (1800 rpm) and 61 kW (82 hp) at 50 Hz (1500 rpm).? PowerTech 4045AFM85 generator-drive en- gine: 110 kW (148 hp) at 60 Hz (1800 rpm) and 89 kW (119 hp) at 50 Hz (1500 rpm). 6.8L ENGINES John Deere 6.8L Tier 3 propulsion and generator- drive engines include the PowerTech 6068AFM85 and the PowerTech 6068SFM85 models, and will cover the power range previously covered by the PowerTech 6081AFM75 propulsion and genera- tor- drive engine. The PowerTech 6068AFM85 and PowerTech 6068SFM85 engines will feature high- pressure common-rail fuel systems, four valves per cylinder and low-temperature aftercoolers. The 6068AFM85 model will be available with keel cooled or integrated heat exchanger options. The 6068SFM85 engine will be offered with an inte- grated heat exchanger conÞ guration.Propulsion power ratings for these engines in-clude:? PowerTech 6068AFM85: 172 kW to 246 kW (230 hp to 330 hp)? PowerTech 6068SFM85: 186 kW to 298 kW (249 hp to 400 hp)Generator-drive 6.8L engine prime power ratings include:? PowerTech 6068AFM85: 166 kW (223 hp) at 60 Hz (1800 rpm) and 139 kW (186 hp) at 50 Hz (1500 rpm)? PowerTech 6068SFM85: 195 kW (262 hp) at 60 Hz (1800 rpm) and 168 kW (226 hp) at 50 Hz (1500 rpm)www.JohnDeere.com/jdpower New Marine Engines John Deere Debuts Tier 3 John Deere 6.8L Tier 3 propulsion and generator- drive engines include the PowerTech 6068AFM85 and the PowerTech 6068SFM85 models, and will cover the power range previously covered by the PowerTech 6081AFM75 propulsion and generator- drive engine.MR #1 (18-25).indd 23MR #1 (18-25).indd 231/2/2013 11:00:59 AM1/2/2013 11:00:59 AM
