Dual Fuel Engines (low-Pressure and pre-mixed lean burn technology)

A full scale dual fuel (DF) test engine was installed in Aioi Plant under the investment of DU/IHI, amount of which is approx 2Billion yen. The engine to be installed in Aioi Plant is a WinGD 6 cylinder X72, one of the newest engines which will be converted to DF and which would be applicable to large LNG carriers. The base technology was developed through a series of the test on a WinGD RT-flex50 where the gas combustion mode was applied on one cylinder. This technology has been expanded now to the large size engines and we verify it on WinGD X72DF test engine in Aioi Plant with the support of Winterthur Gas & Diesel (WinGD). On the other hand, base technologies for the gas combustion have been supported by MITI fund as well as collaboration research scheme with class NK. Those base technologies shall be utilized for the success of DF project.
