Economic engines from Winterthur
The Swiss engine designer WinGD (Winterthur Gas & Diesel) has launched four new short-stroke engines to address economic engine speeds and accommodate space constraints on several vessel types. The range, starting with the X52-S2.0 and X62-S2.0 and their dual-fuel counterparts X52DF-S1.0 and X62DF-S1.0, features a short piston stroke that is ideal for vessels with a shallow draught, small propeller diameter or low main deck height. Container feeders, ro-ro and con-ro vessels, multipurpose cargo vessels and vehicle carriers all have design conditions that demand a shorter stroke.
On the new X62-S2.0 and X62DF-S1.0 engines the piston stroke has been reduced by 413 mm compared to the standard X62 and X62DF– offering a substantial saving in the engine room height needed for installation.
Along with design improvements to reduce maintenance and cut operating costs, the new liquid fuel engines will be fitted with an integrated selective catalytic reduction (iSCR) system. They will be among the first engines to offer the new, compact solution to meeting IMO Tier III NOX limits. (fd)
