摘要

Winterthur Gas and Diesel (WinGD) has demonstrated a run of the first large bore model from its new range of Waertsilae X-DF low-speed two-stroke engines that it says is in response to LNG carrier demand. The X-DF technology features dual-fuel (DF) combustion technology with low pressure gas admission. The system is based on the lean burn Otto cycle - ignition of a compressed lean air-gas mixture by injection of a small amount of liquid fuel. The technology is said to significantly reduce NOx emissions, allowing a wide margin of compliance with IMO Tier III limits in emission control areas (ECAs) without exhaust aftertreatment, combined with high overall system efficiencies for low operating costs and significantly lower investment costs compared to competing technologies. WinGD, in cooperation with Diesel United, demonstrated the 72cm bore Waertsilae' 6X72DF, which is installed as a technology demonstrator at Diesel United's Aioi works near the Port of Kobe, Japan.
