Stage V.

John Deere has billions of hours of field experience with off-highway diesel engine technologies and launched many of its engines ahead of EPA and EU deadlines, and is ready to meet Stage V emissions regulations using our proven diesel particulate filter (DPF) solutions. In most cases, OEM customers currently using a John Deere engine with a diesel particulate filter (DPF) won’t have to re-engineer machine design to meet the requirements of Stage V regulations. Our engineers continue to employ a global network of technical resources and the latest technology to lower emissions while improving performance and fluid efficiency.

Series turbocharger

Air is first drawn into the low-pressure turbocharger and compressed to a higher pressure. The compressed air is then drawn into the high-pressure turbocharger, where the air is further compressed. The high-pressure air is then routed through a charge air cooler and into the engine's intake manifold. By splitting the work between two turbochargers, both can operate at peak efficiency and at slower rotating speeds — lowering stress on turbocharger components and improving reliability. Series turbocharging delivers more boost pressure than single turbocharger configurations, which results in higher power density, improved low-speed torque, and improved high altitude operation.

Exhaust filters

This system is the Best Available Control Technology (BACT) for particulates that delivers premium block load acceptance characteristics, utilizing a catalyzed exhaust filter that contains a diesel oxidation catalyst (DOC) and a diesel particulate filter (DPF). The DOC reacts with exhaust gases to reduce carbon monoxide, hydrocarbons, and some particulate matter (PM). The downstream DPF traps and holds the remaining PM. Trapped particles are oxidized within the DPF through a continuous cleaning process called passive regeneration. Passive regeneration occurs during normal operating conditions when heat from the exhaust stream, and catalysts within the exhaust filter, trigger the oxidation of the trapped PM. If passive regeneration cannot be achieved due to low temperature, load, or speed, then PM is removed using active regeneration — an automatic cleaning process controlled by the exhaust temperature management system.

Cooled exhaust gas recirculation (EGR)

EGR cools and mixes measured amounts of cooled exhaust gas with incoming fresh air to lower peak combustion temperatures, thereby reducing NOx.

Selective catalytic reduction (SCR)

John Deere engines feature an SCR system that utilizes a urea-based additive, sometimes referred to as diesel exhaust fluid (DEF) to meet Stage V emission standards. A chemical reaction in the SCR catalyst converts urea and NOx emissions into nitrogen and water vapor.

High-pressure common-rail (HPCR)

The HPCR fuel system provides variable common-rail pressure and high injection pressures. It also controls fuel injection timing and provides precise control for the start, duration, and end of injection.

Air-to-air aftercooled

This is the most efficient method of cooling intake air to help reduce engine emissions while maintaining low-speed torque, transient response time, and peak torque. It enables an engine to meet emissions regulations with better fuel economy and the lowest installed costs.

4-valve cylinder head

The 4-valve cylinder head provides excellent airflow resulting in excellent low-speed torque and transient response.
