John Deere Power Systems introduced the PowerTech PSL 13.5L prime power generator drive engine, which meets U.S. Environmental Protection Agency Final Tier 4 emissions regulations without the need for a diesel particulate filter (DPF).

This space-saving package is designed to give OEMs more installation options for prime power generator set applications. As with the other engines in John Deere's no-DPF generator drive lineup, this new 13.5L engine employs the company's Integrated Emissions Control system with cooled exhaust gas recirculation (CEGR), a diesel oxidation catalyst (DOC) and a selective catalytic reduction (SCR) system.

The new PowerTech PSL 13.5L generator drive engine is rated at 473 kWm and, in addition to generator sets, can be used to provide power to select constant speed applications. Design features like low idle speeds, dual frequency ratings and easy paralleling are meant to help customers better serve the prime power market.

The new PowerTech PSL 13.5L generator drive engine model joins the existing lineup whose models and power ratings includes:

  • PowerTech PWL 4.5L: 69kWm, 80kWm and 99kWm
  • 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 PVL and PSL 6.8L generator drive engine in late 2015 while the PowerTech, PSL 4.5L, 9.0L and 13.5L generator drive engines will enter production in early 2016.
