Development of a Dual Fuel technology for slow-speed engines
Driven by emission regulations and recent fuel price developments, the interest in gas as fuel for shipping is increasing. For medium speed 4- stroke applications, W(a)rtsil(a) has developed a range of gas and Dual Fuel engines that have penetrated the market and in some applications, like the LNG carrier segment, taken considerable market share. Now W(a)rtsil(a) has initiated the development of a Dual Fuel technology for 2-stroke engines. The technology is based on the pre-mixed lean burn combustion principle previously developed for the 4-stroke engines. The main merits of this technology are that low pressure gas can be utilized, and that no additional NOx reduction technologies are needed to fulfil the IMO Tier III requirements, which will keep both the initial investment cost, as well as operating costs, on a low level. With Dual Fuel capability the engine can be operated both on gas and on HFO. This paper describes the initial design, development, and test results of the technology, including selected engine performance characteristics.
