The new engines are applicable to the 36 to 448 kW (48 to 600 hp) range.
John Deere Power Systems has announced their line-up of Stage V ready engines to meet the recently implemented European Union (EU) Stage V emissions regulations. Catalyst technologies, emissions control calibrations, and next generation after-treatment solutions are used in the John Deere PowerTech™ engines and will permit greater package flexibility and offer easier installation over previous John Deere engines. The engines have increased torque response, low-speed torque and fluid efficiency, and provide more responsive power at higher altitudes. The line-up includes engine displacements of 2.9L, 4.5L, 6.8L, 9.0L and 13.5L with ratings of 36 – 448 kW (48 – 600 hp).
John Deere indicates that OEMs will benefit from the continual product improvements and advancements John Deere is making by retaining the same engine performance in a reduced package size. John Deere has managed to achieve reduced package sizes by using next generation after-treatment solutions that provide up to a 39 percent reduction in size and 57 percent reduction in weight. John Deere state that in order to achieve Stage V emissions levels for engines in the 19 kW to 560 kW power band, manufacturers will have to use DPF (diesel particulate filter) technology. For John Deere OEM customers developing applications not impacted by Stage V regulations, John Deere will continues to offer its Integrated Emissions Control system in various configurations.
