PowerTech PSX 13.5L Engine
WATERLOO, Iowa (March 22, 2011) – John Deere Power Systems (JDPS) is pleased to announce that their PowerTech PSX 13.5L diesel engine has been certified as compliant with Environmental Protection Agency (EPA) Interim Tier 4, European Union (EU) Stage III B and California Air Resources Board (CARB) emissions regulations. The PowerTech PSX 13.5L engine joins the previously certified 6.8L and 9.0L engine models. John Deere’s PowerTech PSX 9.0L, PVX 9.0L, PSX 6.8L and PVX 6.8L above 130 kW (174 hp) engines received EPA Interim Tier 4, EU Interim Stage III B and CARB certification in 2010.
"The certification of our 13.5L engine means that the complete lineup of JDPS engines above 130 kW (174 hp) has achieved regulatory approval," said Doug Laudick, product planning manager for JDPS. "By becoming one of the first off-highway diesel engine manufacturers to certify all of their engines in the power range, we demonstrated our market leadership and commitment to the environment. Not only does our certified Interim Tier 4 engine lineup offer OEMs the right emissions-reduction technology right now, it also delivers our customary performance, reliability, durability and low operating costs."
Interim Tier 4/Stage III B emissions regulations began January 1, 2011, for 130 kW (174 hp) and above engines and require a 90 percent reduction in diesel particulate matter (PM) and a 50 percent reduction in nitrogen oxide (NOx) from previous Tier 3/Stage III A requirements.
John Deere met the challenge of Interim Tier 4/Stage III B regulations by starting with their proven PowerTech Plus Tier 3/Stage III A engine platform – which includes cooled exhaust gas recirculation (EGR) for NOx control – and adding an exhaust filter for reducing PM. The PowerTech PSX 13.5L engine will feature full-authority electronic controls, a 4-valve cylinder head, a high-pressure fuel system, series turbocharging and an air-to-air aftercooling system.
"Certification of our Interim Tier 4/Stage III B engines above 130 kW (174 hp) is a testament to the quality of our field and lab testing processes," Laudick said. "JDPS accumulated an immense number of testing hours to ensure that the final products would meet the unique demands of off-highway applications as well as challenging emissions regulations."
In choosing a solution for Interim Tier 4/Stage III B, John Deere elected not to use selective catalytic reduction (SCR). John Deere's cooled EGR and exhaust filter approach provides OEMs and end users a proven solution with the best total fluid economy. The single-fluid approach of cooled EGR means owners and operators won't have to incur the cost of diesel fuel plus the additional cost for diesel exhaust fluid (DEF) required by SCR systems.
"For Interim Tier 4/Stage III B, we're not only looking at fuel economy, we're taking into consideration total fluid consumption," said Brian Brown, manager of worldwide marketing support for JDPS.
The certified PowerTech PSX 13.5L offers a power range of 298 – 448 kW (400 – 600 hp), and will go into production in March 2011.
