Dimensions
Features and Benefits
High-Pressure Common Rail Fuel System
- Higher (33%) injection pressures, up to 1600 bar (23,000 psi)
- Variable injection pressure and timing control
4-Valve Cylinder Head
- New cylinder head with 4-valve design provides increased air flow resulting in higher low speed torque and better transient response time
John Deere Electronic Control Systems
- Built in controls eliminates the need for costly add on engine warning systems and associated components
- Service diagnostics and error codes automatically stored for later retrieval & ease of diagnostics
- Built in engine synchronization feature
Centered, Vertical Injectors
- Engines burn cleaner, resulting in lower emission and improved fuel economy with the aid of vertical injectors
Watercooled Turbocharger and Exhaust Manifold
- Cooler and quieter environment for vessel and crew
- Reduced external connections eliminates hoses and fittings that can leak or break
Replaceable Wet-type Cylinder Liners
- Excellent heat dissipation
- Hardened and precision machined for long life
- Rebuild to original specifications
High Torque and Low Rated RPM
- Excellent vessel control and maneuvering
- Lower rated rpm limits vibration and noise for better crew comfort
- Lower rated rpm limits vibration and noise for better crew comfort
Heat Exchanger
- High-capacity heat exchanger designed for reliable operation in adverse conditions
Corrosion Resistant Components
- Provides engine protection from the effects of seawater
High Power Density
- High power density offers more power in a smaller package
