Caterpillar launches dual-fuel MaK 34 DF

摘要

Caterpillar has formally announced that it is developing a dual-fuel version of another of its MaK medium-speed propulsion engines. The M 34 DF is based on the M 32 C, with which it shares the footprint and major dimensions. It is rated at 500 kW/cylinder at 720 and 750 rpm in diesel and gas modes. Caterpillar claims that although designed for unlimited operation on LNG, marine diesel oil and HFO, the M 34 DF will reach industry- leading efficiency in gas mode. First engine deliveries are foreseen for October 2014, in time for the January 2015 ECA fuel sulphur limit changes.
