Catalogue excerpts

The WARTSILA® 50DF tri-fuel engine is the ultimate ‘fuel flexibility’ solution. It is a four-stroke engine that runs on light fuel oil (LFO) or heavy fuel oil (HFO), and can switch over from gas to LFO/HFO and vice versa smoothly during engine operation. The Wartsila 50DF is manufactured in configurations from 6L up to 16V giving 950/975 kW per cylinder and a total maximum mechanical output of 15,600 kW. The engine speed is 500 or 514 rpm for use with 50 or 60 Hz applications. The engine has a maximum thermal efficiency of 47%, higher than for any other gas engine. Typical Application Areas Wartsila 50DF is suitable for a wide range of applications in various respects. Thanks to modular and compact design the engine can be installed and optimised for constant speed generating sets as well as variable speed for mechanical drive applications for main engines. Utmost power-to-weight and power-to-space rations of the Wartsila 50DF offer various machinery opportunities for different vessel applications. The Wartsila 50DF can be installed as mechanical drive prime mover for smaller applications, like small cargo vessels, ferries or tug boat installations. Wartsila 50DF is also optimal for genset application for a wide range of vessel types. Flexibility in engine support arrangements allows optimised rigid or flexible foundation for a wide range of application types in marine and land based power solutions. Key Benefits • Proven and reliable heavy fuel technology • Easy and cost-effective installation • Long overhaul intervals • Low exhaust gas emissions • Fuel economy over the entire engine operation range • Minimal consumables thanks to modular design • Embedded automation system

Operation Features The engine can be switched automatically from fuel oil to gas operation at loads below 80% of the full load. Transfer takes place automatically after the operator's command without load changes. During switchover, which lasts about one minute, the fuel oil is gradually substituted by gas. In the event of for instance a gas supply interruption, the engine converts from gas to fuel oil operation at any load instantaneously and automatically. Futhermore, the separate liquid fuel system makes it possible to switch over from LFO to HFO without load reduction. The pilot fuel is in...
