John Deere Power Systems (JDPS) extended its generator drive power solutions with the introduction of four new PowerTech prime power generator drive engines at Intermat. The new engines meet U.S. Environmental Protection Agency (EPA) Final Tier IV emissions regulations without the need for a diesel particulate filter (DPF) — giving OEMs with space-constrained installations more options for their prime power generator set applications. The engines utilize a John Deere integrated emissions control system equipped with cooled exhaust gas recirculation (CEGR), a diesel oxidation catalyst (DOC), and a selective catalytic reduction (SRC) system, and join the existing lineup of Final Tier IV generator drive engines that use the same technologies plus a DPF.
“We’ve been able to develop constant speed engines that do not require a diesel particulate filter to meet both stringent emissions regulations and the performance our customers have come to expect,” said Darrin Treptow, manager, worldwide marketing of John Deere Power Systems.
Product enhancements including increased power, low idle speeds, dual frequency ratings and easy paralleling enhance customer performance for prime markets. Low idle speed capability reduces fluid consumption and decreases wear on the engine during transport or start-up and shutdown checks. Electronic controls enable easy synchronization when operating generator sets in parallel, while offering flexible dual frequency operations of 50 Hz at 1500 rpm or 60 Hz at 1800 rpm. In addition to generator sets, these engines can provide power to selected constant speed applications, according to the manufacturer.
“Our engines offer an ideal and efficient solution for prime power in a wide variety of operating conditions,” Treptow said.
New PowerTech generator drive engine models and power ratings include:
• PowerTech PSL 4.5L: 128 kWm
• PowerTech PVL 6.8L: 160 kWm and 192 kWm
• PowerTech PSL 6.8L: 216 kWm and 240 kWm
• PowerTech PSL 9.0L: 273 kWm, 326 kWm and 345 kWm
John Deere plans to begin production of the PowerTech PSL 4.5L generator drive engine in late 2015 while the PowerTech PVL 6.8L, PSL 6.8L and 9.0L generator drive engines will enter production in 2016.
“We listened to generator set manufacturers to understand the features and services they needed to meet the challenges they face. That’s why our new engines continue to offer easy operation and compact generator set packaging, all while continuing to meet customer performance expecations,” Treptow said.
John Deere is one of the few manufacturers that build engines exclusively for off-highway applications. This specialization has given John Deere experience in developing and packaging generator drive engines. John Deere engines deliver performance, power, fluid efficiency, reliability, easy installation and emissions compliance to both generator set OEMs and end users, according to the manufacturer.
John Deere offers an extensive lineup of standby and prime generator set engines that meet emissions regulations while delivering quick-starting, clean-running and fuel-efficient performance. The full lineup of John Deere generator drive engines ranges in displacement from 2.9L to 13.5L and covers generator drive ratings from 42 to 755 hp (31 to 563 kWm). These engines include non-emissions certified, EU Stage II and Stage III A, EPA Tier III, Interim Tier IV and Final Tier IV models.
