2018 John Deere Engine & Drivetrains 6068HF285 (139 - 200 hp)
6.8L Industrial Diesel Engine
Emissions Certifications
- CARB
- EPA Tier 3
- EU Stage III A
Features may include:
2-valve cylinder head- Cross flow head design that provides excellent breathing from a lower cost two-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
- Fixed geometry turbochargers are sized for a specific power range and optimized to provide excellent performance across the entire torque curve. They are also designed to maximize fuel economy between the engine's rated speed and peak torque
- 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
- The new HPCR fuel system and engine control unit (ECU) allow for multiple fuel injections. The number of fuel injections, based on speed and load, help contribute to lower combustion temperatures, which reduce the formation of NOx and particulates. The multiple injection strategy also provides an added benefit of noise reduction
- New power bulge feature
- Increased low-speed torque
- New higher-peak torque ratings
- Faster torque rise
- Lower-rated speeds available for reduced noise and improved fuel economy
- Mounting points are the same as Tier 2/Stage II engine models
- PowerTech E engines offer electronically controlled fuel systems with improved cold-start performance, precise engine speed control, torque curve shaping and more. Because these systems have less need for redundant sensors, add on electronic governors, and shutdown devices they result in a lower total installed cost
- Self-adjusting poly-vee fan drive
- Forged-steel connecting rods
- Replaceable wet-type cylinder liners
- Either-side service
- 500-hour oil change
- Gear-driven auxiliary drive
