Caterpillar MaK engines achieve Tier 2 certification
Caterpillar Marine Power Systems announced the EPA Tier 2 Certification of all MaK engine platforms with cylinder volumes of above 30 L.
Included in the certification are the M 32 C, M 43 C and M 46 DF, as well as the recently announced M 34 DF engine platform. Cat said the certification of the broad range of MaK power solutions provides customers operating in the American market – specifically in the commercial and offshore marine markets – with a wide spectrum of power nodes to meet emissions regulations on U.S. flagged vessels.
The M 34 DF dual-fuel engine boasts a power rating of 500 kW per cylinder at 720 and 750 r/min in diesel and gas modes and will share the same footprint as the M 32 C engine series. As of 2015, the M 34 DF will be capable of running on natural gas as an alternative to marine diesel oil or large and complex scrubber installations for Emission Control Areas (ECA) operations, the company said.
