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. In his opening speech at the event, Jaakko Eskola, Senior Executive Vice President and President, Wärtsilä Ship Power, stated: “Dual-fuel engine technology is the future; it is a tide that cannot be turned back. Gas is certain to play an increasingly imp... [More]
Dual-fuel (DF) diesel engine demand in land and marine power markets has stimulated designs from leading engine builders over the past decade, not least Caterpillar, who say they are working on a new medium-speed dual fuel engine the M34DF.Development of these engines is spurred by the increased availability of gaseous fuels, the much lower level of noxious exhaust emissions associated with them, as well as the benefits of reduced engine maintenance and longer intervals between power plant overhauls. Natural gas is also a safe fuel, both lighter than air and with a relatively high ignition temperature.

Caterpillar’s MaK™ product line, manufactured in Germany and China will feature the new M 34 DF from October 2014. It has a power rating of 500 kW per cylinder at 720 and 750 rpm in diesel and gas modes, and will share the same footprint as the popular M32C engine series.“It was important for us th... [More]
