John Deere has always been ahead of the game when it comes to meeting emissions regulations. Interim Tier 4/Stage III B is no exception. We pioneered the use of many advanced technologies with our Tier 3/Stage III A engines and proved their performance in off-highway applications. This gives us a head start for fuel economy as well as delivering higher power bulge, more torque rise, and faster transient response time.

PowerTech PVX | |
|
138 – 224 kW (185 – 300 hp) | |
|
| |
|
Improved performance and efficiency
| |
| |
When you need unparalleled performance, PowerTech PVX 6.8L or 9.0L engines are the perfect fit for your application. Both displacements utilize our proven PowerTech Plus technology with variable geometry turbocharging (VGT) to improve performance and combustion efficiency, reduce emissions and increase fuel economy.

PowerTech PSX | |
|
168 – 448 kW (225 – 600 hp) | |
|
| |
|
Ultimate performance and responsiveness
| |
| |
For ultimate performance in off-highway applications that take you up and down steep grades at high altitudes. Or when you simply want maximum transient response and low-speed torque.
A PowerTech PSX 6.8L, 9.0L, or 13.5L engine is exactly what you need. Along with proven PowerTech Plus technology, all three displacements feature series turbochargers that improve performance and responsiveness.

First in its field | |
|
|
| |
|
John Deere was the first engine manufacturer to take advantage of cooled exhaust gas recirculation (EGR) and variable geometry turbocharger (VGT) technologies in off-highway applications, introducing them with Tier 3/Stage III A emissions regulations. Our engines have a proven record of emissions reduction, best-in-class fuel economy, and rugged reliability. By choosing EGR first, we proved cooled exhaust gas recirculation could meet emissions regulations and deliver high performance without the continuing cost and inconvenience of SCR. When it comes to off-highway performance, other engine manufacturers can only follow in our tracks.

Best-in-class fuel economy | |
|
|
| |
|
John Deere achieved record fuel economy gains and claimed best-in- class fuel economy with our Tier 3/Stage III A PowerTech Plus engines. The PowerTech Plus 9.0L engine set fuel economy records during independent testing at the Nebraska Tractor Test Lab, consuming nearly 9 percent less fuel than its predecessor. Other engine manufacturers are just now introducing the use of cooled EGR and VGT in their off-highway Interim Tier 4 product offerings. Because John Deere Interim Tier 4/Stage III B engines build on our already proven technologies, we expect to maintain fuel-economy leadership in the off-highway industry.

Smart exhaust filters | |
|
|
| |
|
Interim Tier 4/Stage III B PowerTech engines 130 kW (174 hp) and above will utilize a catalyzed exhaust filter that contains a diesel oxidation catalyst (DOC) and a diesel particulate filter (DPF). Under normal operating conditions, the DOC reacts with exhaust gases to reduce carbon monoxide, hydrocarbons, and some particulate matter (PM). The downstream DPF forces exhaust gases to flow through porous channel walls, trapping and holding the remaining PM. Trapped particles are eventually oxidized within the DPF through a self-activating cleaning process called passive regeneration, utilizing exhaust heat created under normal operating conditions.

The jobs that John Deere PowerTech engines tackle every day are as varied as the equipment they power. That’s why John Deere Interim Tier 4/Stage III B engines integrate many technologies designed to meet the unique needs of off-highway equipment. PowerTech 6.8L, 9.0L, and 13.5L engines use our proven PowerTech Plus technology which includes 4-valve cylinder heads, cooled EGR, VGT, air-to-air aftercooling, high-pressure fuel systems, and wet-type cylinder liners.
