Engine developer WinGD (Winterthur Gas & & Diesel Ltd) has actually released 4 brand-new short-stroke engines to fulfill the financial engine rate needs and also area restrictions on numerous vessel kinds.
The variety, beginning with the X52-S2.0 and also X62-S2.0 and also their dual-fuel equivalents X52DF-S1.0 and also X62DF-S1.0, include a brief piston stroke appropriate to vessels with a superficial draft, tiny prop size or reduced major deck elevation.
Vessel kinds with styles requiring a much shorter engine stroke consist of container feeders, RO/RO and also ConRo vessels, multi-purpose freight vessels and also car service providers.
On the brand-new X62-S2.0 and also X62DF-S1.0 engines the piston stroke has actually been decreased by 413 mm contrasted to the common X62 and also X62DF– providing a considerable conserving in the engine area elevation required for setup.
“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,” claimed 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.”
As well as making the engines extra small, the brand-new stroke-to-bore proportion likewise decreases production and also part expense. Along with layout enhancements to decrease upkeep and also cut operating expense, the brand-new fluid gas engines will certainly be fitted with an incorporated careful catalytic decrease (iSCR) system. They will certainly be amongst the initial engines to supply the brand-new, small option to conference IMO Tier III NOX limitations.
“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,” claimed Galke.
The X62-S2.0 engine has a cyndrical tube birthed size of 620 mm and also a piston stroke of 2,245 mm– contrasted to a stroke of 2,658 mm on the common X62– with an optimum continual power of 2,685 kW/cylinder at 108 rpm. The engine will certainly be readily available with 5 to 8 cyndrical tubes, covering a total power series of 7,600-21,480 kW at 85-108 rpm.
The X62DF-S1.0 engine has comparable measurements and also an optimum continual power of 2,110 kW/cylinder, for a total power series of 6,925-16,880 kW.
The X52-S2.0 engine has a cyndrical tube birthed size of 520 mm and also a piston stroke of 2,045 mm, with an optimum continual power of 1910 kW/cylinder at 120 rpm. The engine will certainly be readily available with 5 to 8 cyndrical tubes, covering a total power series of 5,425-15,280 kW at 95-120 rpm. The X52DF-S1.0 engine has an optimum continual power of 1500 kW/cylinder and also covers a total power series of 4,950-12,000 kW.
The initially of the brand-new engines, a six-cylinder variation of the X62-S2.0 engine, will certainly be examined at the end of 2021. The initial X52-S2.0 engine will certainly comply with 6 months later on.
