John Deere Announces New 4.5L, 6.8L Tier 3 Marine Engines at International WorkBoat Show

WATERLOO, Iowa (December 5, 2012) — John Deere Power Systems (JDPS) is pleased to announce new Marine Tier 3 PowerTechTM 4.5L and 6.8L propulsion and generator-drive engines at the International WorkBoat Show, Dec. 5 – 7 in New Orleans. John Deere will meet U.S. Environmental Protection Agency (EPA) Marine Tier 3 emissions regulations 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. These engines also will achieve compliance with International Maritime Organization (IMO) Tier II emissions regulations and EU 97/68/EC.

 

New EPA Marine Tier 3 regulations will impact John Deere 4.5L and 6.8L engines beginning January 1, 2013. Tier 3 regulations affecting John Deere 9.0L and 13.5L marine engines start in 2014.

 

New 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 PowerTech 4045AFM85 propulsion and generator-drive engine.

 

The PowerTech 4045TFM85 generator-drive engine will offer quiet and smooth operation for gen-set applications. Features will include 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 more powerful and compact choice in the power range that was previously covered for Tier 2 by the PowerTech 6.8L 6068TFM75 propulsion and PowerTech 6.8L 6068TFM76 generator-drive engines. The PowerTech 4045AFM85 engine will feature a high-pressure 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 4045TFM85: 74 kW (99 hp) at 60 Hz (1800 rpm) and 61 kW (82 hp) at 50 Hz (1500 rpm)

 

"The PowerTech 4045AFM85 is the most powerful John Deere 4.5L marine engine ever launched," Micu said. "With more power in a smaller package, the engine is a good choice for propulsion of small utility boats, workboats, trawler yachts, and commercial fishing boats. The generator-drive version will be an excellent engine for commercial and recreational generators."

 

New 6.8L engines

 

John Deere 6.8L Tier 3 propulsion and generator-drive engines include the PowerTech 6068AFM85 and the PowerTech 6068SFM85 models. These engines will cover the power range previously covered by the popular PowerTech 6081AFM75 propulsion and generator- 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 integrated heat exchanger configuration.


Propulsion power ratings for these engines include:

  • 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)

 

"John Deere integrated features into our newest 6.8L and larger Tier 2 marine engines with Tier 3 emissions regulations in mind," said Carl Micu, global sales and marketing project manager for JDPS. "As a result, we will be able to make a seamless transition to Tier 3 emissions regulations. John Deere Tier 3 marine engines will meet the more stringent emissions regulations while maintaining similar performance and a similar package size."

 

John Deere will continue to offer Tier 2 and non-certified marine engine models for regions and applications not impacted by the new regulations.
