The remarkable significance of a new marine diesel technology just announced by Wärtsilä is that the low pressure, dual-fuel (gas/liquid fuel) benefits that are already available to 4-stroke engines, can now be applied to 2-stroke engines as well, thus making the technology available to the broader merchant shipping market.

Wärtsilä, having announced the successful full scale testing on gas of an RT-flex50DF engine, say that the marine industry is already showing significant interest, evidenced by the fact that more than 130 industry executives from 89 leading shipping companies attended the recent introductory event in Trieste, Italy.

Wärtsilä announce the addition of two new 62 and 72 bore engine series to their RT-flex two stroke, low speed programme. The new engines offer significant benefits to both shipowners and operators by way of high propulsion efficiency, reliability, and optimised total cost of ownership. The two new engine series employ well-proven Wärtsilä low-speed technology, together with electronically-controlled fuel supply and control. Wärtsilä's licensee partners in Asia are closely involved in the manufacturing process and all Wärtsilä licensees will have the right to build the new engines. Availability of the 62 is Sept 2013 and 2014 for the 72. [More]
