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]
