Information
2018 John Deere Engine & Drivetrains 6068HFG85 193-235 kW
6.8L Generator Drive Engine
Emissions Certifications
Features may include:
Jet fuel capable- The John Deere jet fuel capable engines run on military, arctic, and aviation fuel, including Jet A, Jet A-1, JP-5, and JP-8. If you need to switch back to diesel fuel, just fill up the tank and go
4-valve cylinder head- Provides excellent airflow resulting in better transient response
High pressure common rail fuel system- HPCR: Higher injection pressures, up to 1600 bar (23,000 PSI) variable injection pressure, variable timing control, multiple injections and controls the duration of injection
Cooled exhaust gas recirculation (EGR)- Cools and mixes measured amounts of cooled exhaust gas with incoming fresh air to lower peak combustion temperatures, thereby reducing NOx
Variable geometry turbocharger-VGT- Varies exhaust pressure based on load and speed to insure proper EGR flow, quicker transient response for exceptional block-loading, and best-in-class fuel economy
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
Compact size- Horsepower/displacement ratio is best-in-class
- Mounting points for Tier 3/Stage III A engine models same as Tier 2/Stage II engine models
John Deere electronic engine controls- Monitors critical engine functions providing warning and/or shutdown to prevent costly engine repairs; eliminates need for add-on governing components; all lowering total installed costs. Snapshot diagnostic data that can be retrieved using commonly available diagnostic service tools
- New common wiring interface connector for vehicles or available OEM instrumentation packages; new solid conduit and "T" connectors to reduce wiring stress, greater durability and improved appearance
- Factory installed engine mounted ECU or remote mounted ECU, wiring harness and associated components
- Industry standard SAE J1939 interface which communicates with other vehicle systems, eliminating redundant sensors and reducing vehicle installed cost
Additional features- Self adjusting poly-vee fan drive
