John Deere Power Systems

John Deere Power Systems (JDPS) manufactures and markets 30 kW to 448 kW (40 hp to 600 hp) industrial diesel engines and 56 kW to 559 kW (75 hp to 750 hp) marine diesel engines, as well as drivetrain components for use in a variety of off-highway applications. JDPS serves the agriculture, generator-set, industrial, marine and mining markets.

Interim Tier 4/Stage III B solutions

John Deere’s complete line of Interim Tier 4/Stage III B diesel engines is built upon simple, fuel-efficient and field-proven technologies that meet increasingly stringent emissions regulations without sacrificing performance, reliability, durability or operator convenience. Power ratings range from 36 kW to 448 kW (48 hp to 600 hp).

For engines 56 kW (75 hp) and above, John Deere will start with their proven PowerTech™ Plus Tier 3/Stage III A engine platform—which includes cooled exhaust gas recirculation (EGR) for NOx control—and add an exhaust filter for reducing particulate matter. Displacements in this power range include the 4.5L, 6.8L, 9.0L and 13.5L in-line, four- and six-cylinder engines, all of which feature a four-valve cylinder head, high-pressure fuel system, turbocharging and an air-to-air aftercooling system.

Engines between 56 kW (75 hp) and 129 kW (173 hp) will be available in 4.5L and 6.8L displacements and come equipped with either a wastegate or variable geometry turbocharger, depending upon the size of the engine. Compared to John Deere’s larger engines, models between 56 kW (75 hp) and 129 kW (173 hp) will feature smaller exhaust filters that can be engine-mounted or remote-mounted for increased flexibility. Engines in this power range will use an in-cylinder dosing strategy, while John Deere’s 130 kW (174 hp) and above engines use an external dosing system integrated into the exhaust system.

The John Deere PowerTech M 2.4L engine meets Interim Tier 4 and Stage III A emissions regulations and the PowerTech M 4.5L meets Interim Tier 4 emissions regulations without the use of cooled EGR or an exhaust filter.

Power generation

John Deere offers an extensive lineup of standby and prime gen-set engines that meet emissions regulations while delivering quick-starting, clean-running and fuel-efficient performance. Emergency stationary applications are not required to meet Interim Tier 4 regulations. However, the prime power applications are required to meet Interim Tier 4 regulations starting in 2011. The Interim Tier 4 engines range from 2.4L - 13.5L of displacement with prime power ratings of 33 kVA (27 kWe) to 455 KVA (364 kWe) at 60 Hz. These engines will utilize the same technologies as outlined in the previous section.

John Deere’s full lineup of generator-drive engines also includes non-emissions certified; European Union Stage II and Stage III A; and U.S. Environmental Protection Agency Tier 1, 2, 3 models.
