2024 John Deere Engine & Drivetrains Generator Drive Engines 6068HFG05

6.8L Generator Drive Engine

Features may include:

• These engines use diesel oxidation catalyst (DOC) and selective catalaytic reduction (SCR) technology to meet Final Tier 4 emission regulations. They meet customer performance without the need for a diesel particulate filter (DPF).

• Heavy-duty components that are usually found in our larger engines are used throughout our generator drive engine line. Many of our DOC/SCR engines feature top-liner cooling, steel pistons, and variable-speed fan drives.

• Varies exhaust pressure based on load and speed to ensure proper EGR flow. The combination of the cooled EGR and VGT provide low-speed torque, quicker transient response, higher-peak torque, and world-class fuel economy.

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

• The HPCR fuel system provides variable common-rail pressure, multiple injections, and higher injection pressures up to 2,500 bar (36,000 psi). It also controls fuel injection timing and provides precise control for the start, duration, and end of injection.
