In response to the rising demand for extra environment friendly and dependable marine propulsion that serves the wants of an more and more environmentally sustainable trade, WinGD (Winterthur Fuel & Diesel Ltd.) has launched three new low-speed, two-stroke engines which are able to working on low emission fuels.
Constructing on the confirmed WinGD expertise, the brand new additions to the portfolio—X40DF, X82D and X82DF engines—will present a greater variety of compliant decisions to the ship proprietor.
Our trade is asking for greener-shipping and the success of our low-pressure dual-fuel X-DF portfolio is proof that ship homeowners are in search of sustainability and effectivity from their propulsion system. Rising our portfolio of engines ensures that ship homeowners have the correct choices to really feel assured of their funding.—Klaus Heim, CEO WinGD
X40DF engine for smaller vessels. The brand new X40DF in its customary configuration is designed to run on LNG, providing the primary two-stroke dual-fuel engine for smaller vessels. Because the engine is already compliant with all present emission laws, together with IMO Tier III, the complete help system is diminished as a result of absence of the necessity for any exhaust-gas after-treatment system.
The X40DF, low-pressure, dual-fuel engine is obtainable in 5 to eight cylinder configuration, overlaying an influence vary from 2,775 kW to 7,480 kW, at 104 to 146 rpm.
X82-D engine for bigger vessels. For bigger vessels, WinGD’s new X82-D engine is Twin Gas (DF) prepared, with the flexibility to improve to operation with LNG, fulfilling necessities for gas-ready notations from Classification Societies.
The cylinder distance has been diminished to 1440mm from 1505mm, in comparison with the earlier X82-B model within the WinGD portfolio. The brake particular gasoline consumption (BSFC) has additionally been diminished relying of the score level and the tuning variant chosen. The X82-D engine affords enhanced propulsion choices inside the VLCC, VLOC and Panamax container vessel segments.
Provided inside WinGD’s Technology-X engine portfolio, the X82-D engine sits amongst engines recognized for prime thermal effectivity, low gasoline consumption, excessive reliability and extended intervals between overhauls (TBO). The X82-D engine can be obtainable from 6 to 9 cylinders, overlaying an influence output from 16,560 kW at 58 rpm to 49,500 kW at 84 rpm.
Key advantages of the X82-D embrace diminished engine size and weight, as a consequence of shorter cylinder distance with tailored bearing, and structural design for reliability.
The engine affords a put on resistant ICU MK-III with easier overhaul idea and the WiCE (WinGD Built-in Management Electronics) engine management system with extra functionalities supporting extended overhaul intervals. All cylinder configurations are potential with a one piece crankshaft design additional lowering engine size and with pistons fitted with two piston rings for diminished friction losses. The X82-D has additionally been designed with optimized liner design to keep away from cold-corrosion occurring inside the cylinder.
Gas financial savings amounting to US$1170/day (2.6 ton/day consumption at assumed HFO price of US$450/ton) might be achieved for a VLCC operating and X82-D engine at 90% engine energy. That is achieved because of an elevated firing strain facilitating the numerous gasoline financial savings for vessels utilizing the 7X82-D engine in contrast with its predecessor engine, the 7X82-B.
X82DF dual-fuel engine. Permitting for a similar enhanced propulsion choices because the X82-D for bigger vessels, the brand new X82DF is the most recent providing in WinGD’s low-pressure X-DF dual-fuel engine portfolio. The engine dimensions are based mostly on that of the X82-D diesel engine design however follows the Otto-cycle combustion precept wherein gasoline and air are premixed on the proper air-to-fuel ratio.
The X82DF engine has an built-in gasoline strain regulation unit (iGPR), changing the standalone GVU. The pre-chamber expertise and the superior design of the low-pressure gasoline admission valves affords a excessive stage of combustion stability and diminished emissions.
The X82DF NOx emissions produced are beneath that of the IMO Tier-III stage in gasoline mode with out advanced and dear exhaust gasoline after-treatment. On account of the low quantity of pilot gasoline required (x emissions are additionally achieved.
The low-pressure gasoline parts of the engine permit for easy operation, upkeep and overhaul, and guarantee most security, in addition to decrease CAPEX and auxiliary energy demand.
For the reason that launch of the X-DF engine collection in 2013, the expertise has confirmed dependable and environment friendly by way of greater than 230,000 operating hours on 212 engines in operation and/or on order.
