WinGD Debuts Engines In New Short-Stroke Version To Address Space Constraints & Speeds

Last updated on September 11th, 2020

Four new short strike engines have been launched by WinGD (Winterthur Gas & Diesel Ltd). This will be effective for economic engine speeds and will help overcome space restrictions on various types of ships.

The range that starts with the X52-S2.0 and X62-S2.0 and their dual-fuel counterparts X52DF-S1.0 and X62DF-S1.0 are equipped with a short piston stroke that is the best for ships with shallow draught, small propeller diameter or low main deck height.

The design of container feeders, ro-ro and con-ro vessels, multipurpose cargo vessels and vehicle carriers, all require shorter stroke. The piston stroke has been decreased by 413mm in the new X62-S2.0 and X62DF-S1.0 engines in comparison to that in the standard X62 and X62DF.

“Our new short-stroke engine series offers a tailored solution for smaller vessels that still require the efficiency and power of two-stroke marine engines,” said Volkmar Galke, Global Director, Sales WinGD. “Many of these vessel types are part of an aging fleet that means we expect significant fleet renewal – and a big opportunity for our new engines – over the next few years.”

Not only will this make the engines more compact but also the manufacturing and component cost will reduces because of the new stroke-to-bore ratio. In addition to the improvements in design for the reduction of maintenance and cut operating costs, integrated selective catalytic reduction (iSCR) system will also be installed in the new liquid-fuel engines. They will be one of the first engines that will provide new and compact solutions to meet IMO Tier III NOX limits.

“Both the iSCR and the short-stroke series highlight our commitment to simplifying engine installation for shipyards and therefore reducing costs for owners and operators,” said Galke.

The diameter of the cylinder bore used in the X62-S2.0 engine is 620 mm and a piston stroke of 2,245 mm. Five to eight cylinders will be available with the engine that will cover power range of about 7,600-21,480 kW at 85-108 rpm. The dimensions of the X62DF-S1.0 engine is similar and a maximum continuous power of 2,110 kW/cylinder, for an overall power range of 6,925-16,880 kW.

The diameter of a cylinder of the X52-S2.0 will be 520 mm and a piston stroke of 2,045 mm along with maximum continuous power of 1910 kW/cylinder at 120 rpm. Five to eight cylinders will be available with the engine that will cover an approximate power range of 5,425-15,280 kW at 95-120 rpm. The X52DF-S1.0 engine has a maximum continuous power of 1500 kW/cylinder and an overall power range of 4,950-12,000 kW is covered.

One of the new engines which is six-cylinder version of the X62-S2.0 engine, will be tested at the end of 2021. After six months the first X52-S2.0 engine will follow.
