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. Dual-fuel Diesel Engine M34DF: Image courtesy of Caterpillar 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...

Caterpillar Marine Power Systems recently announce the development of a new MaK M46DF series as a dual fuel engine suitable for electric or mechanical propulsion. The 46DF series is offered with a power output of 900 kW per cylinder at both 500 and 514 rpm engine speeds. When operating on LNG, it complies with IMO III as well as EPA Tier 4 regulations.
The new M46DF series has the same main dimensions and interfaces as the 43C series, simplifying the substitution of the 46DF engine in 43C applications and there is the possibility to retrofit existing 43C engines to dual fuel operation. Availability of the DF series is 2014. [More]
