Extended generator drive emergency stationary power ratings

John Deere Power Systems announces new 6.8L generator drive emergency stationary power ratings.

Waterloo, Iowa, December 13, 2010—John Deere Power Systems (JDPS) will introduce extended generator drive emergency stationary power ratings for its PowerTech E 6.8L diesel engine at POWER-GEN International 2010, Dec. 14 – 16 in Orlando, Fla.

The PowerTech E 6.8L, 6068HFG82, is the first John Deere engine to carry both Environmental Protection Agency (EPA) Tier 3 Emergency Stationary and European Union (EU) Stage III A certification, with dual frequency ratings of 1800 and 1500 rpm.

“PowerTech E technology is optimized for performance in emergency stationary gen-set applications and provides superior block-loading capability in every operating condition,” said Vincenzo Perrone, power generation business manager for JDPS. “Adopting this 6.8L engine to meet Tier 3 and Stage III A helps the OEM’s reduce their product complexity by offering a standardized solution in a critical range of power nodes and electric frequencies.”

The 212 kWm rating at 1,800 rpm is currently available from John Deere with a PowerTech Plus 6.8L engine, but the new engine will provide gen-set owners a competitive advantage by offering a dual frequency PowerTech E engine at the same power level. Before the introduction of these new ratings, the highest PowerTech E 6.8L power rating was 177 kWm at 1,800 rpm. The 20 percent power increase from the existing PowerTech E 6.8L platform adds to the JDPS engine lineup that meets power generation needs and emissions regulations worldwide. Gen-set customers can now utilize the PowerTech E platform from 60 – 345 kW with 2.4L, 3.0L, 4.5L, 6.8L and 9.0L displacements.

John Deere’s entire Stage III A lineup employs dual frequency, and the PowerTech E 6.8L is the first Tier 3 engine available with dual frequency that meets both Tier 3 and Stage III A emissions regulations.

Extended emergency standby power ratings for the PowerTech E 6.8L include:
• 202 kWm at 1500 rpm (213 – 225 kVA and 170 – 180 kWe)
• 212 kWm at 1800 rpm (218 – 230 kVA and 174 – 185 kWe)

The 6068HFG82 is an extension of the Tier 3 6068HF285 engine that is available today and continues to feature a fixed-geometry turbocharger, high-pressure common-rail fuel system, 2-valve cylinder head, air-to-air aftercooling and full-authority electronic controls. Additional features and benefits of the 6068HFG82 include increased power density, dual frequency with the same hardware and software sets, and lower heat rejection allowing the use of a simpler and more economical cooling package.

John Deere’s full lineup of generator-drive engines includes non-emissions certified; European Union Stage II and III A; and U.S. Environmental Protection Agency Tier 1, 2, 3 and Interim Tier 4 models ranging from 2.4L – 13.5L of displacement and covering gen-set ratings from 31 – 473 kW (42 – 634 hp).
