2018 John Deere Engine & Drivetrains 6068HF485 (180 - 275 hp)

6.8L Industrial Diesel Engine

Emissions Certifications

• CARB

• EPA Tier 3

• EU Stage III A

Features may include:

• 4-VALVE CYLINDER HEAD

• The HPCR fuel system provides variable common-rail pressure, multiple injections, and higher injection pressures, up to 1600 bar (23,000 psi). It also controls fuel injection timing and provides precise control for the start, duration, and end of the injection

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

• Varies exhaust pressure based on load and speed to insure proper EGR flow; greater low-speed torque, quicker transient response, higher peak torque, and best-in-class fuel economy

• 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

• Horsepower/displacement ratio is best-in-class

• Lower installed cost

• Mounting points are the same as Tier 2/Stage II engine models

• Multiple rated speeds to further reduce noise and improve fuel economy

• New higher peak torque ratings

• Better transient response time

• Greater levels of low speed torque

• Higher levels of power bulge

• Electronic engine controls monitor critical engine functions, providing warning and/or shutdown to prevent costly engine repairs and eliminate the need for add-on governing components all lowering total installed costs. Snapshot diagnostic data that can be retrieved using commonly available diagnostic service tools

• Controls utilize new common wiring interface connector for vehicles or available OEM instrumentation packages; new solid conduit and "T" connectors to reduce wiring stress and provide greater durability and improved appearance

• Factory-installed, engine mounted ECU or remote-mounted ECU comes with wiring harness and associated components. Industry-standard SAE J1939 interface communicates with other vehicle systems, eliminating redundant sensors and reducing vehicle installed cost

• Glow plugs

• Gear-driven auxiliary drives

• 500-hour oil change

• Self-adjusting poly-vee fan drive

• R.H. and L.H. engine-mounted fuel filters
