COMPACTNESS
- Most powerful four-stroke dualfuel engine
- Simple and robust design
- Controlled by an advanced automation system
HIGH EFFICIENCY
- High output with fuel flexibility
- Low emission rates
- Provides the same output with natural gas or on LFO/HFO
HIGH FLEXIBILITY
- A pilot fuel ignited lean-burn gas engine
- Instant switch-over capability to back-up fuel
- Monoblock injection pump and engine-driven pilot fuel pump
EASY MAINTENANCE
- Long component lifetime and time between overhauls
- Hydraulic jack for easy manoeuvring of the bearing cap
- Large scale of common components with Wärtsilä 32DF and Wärtsilä 46
BUILT-IN EXPERIENCE
- Basic design from Wärtsilä 46 engine
- Anti-polishing ring consept
- Proven lean-burn technology with conventional diesel fuel technology
Maintenance
- A large opening into the crankcase and camshaft to facilitate checking and maintenance
- The three-piece connecting rod allows inspection of the big end bearing without removal of the piston, and piston overhaul without dismantling the big end bearing
- The camshaft is built of identical cylinder segments fastened to intermediate bearing pieces
- The pilot fuel pump is located in the free end of the engine
- Easy access to the piping systems is obtained by removing the insulating panels
- Electrically controlled gas admission valves reduce the need for mechanical parts and periodic adjustments
- A resiliently mounted insulating box provides easy access to the exhaust system
Condition-based maintenance
- Available as standard support for Wärtsilä 50DF
- Monthly report from Wärtsilä on status of engine condition and recommendations for corrective actions resulting in:
- Optimized life-cycle efficiency
- Minimized environmental impact
- Optimized operating economy
Global service support
