Cat Dual-Fuel Marine Engine
Designed with same footprint features, system interfaces; option for offshore, cargo segments
Caterpillar is introducing a dual-fuel engine for marine applications. The company said the MaK M 34 DF has the same onboard footprint as the existing M 32 C diesel engine series and is suitable for a wide range of vessels.
The M 34 DF has a power rating of 500 kW per cylinder at 720 and 750 r/min in diesel and gas modes, respectively, with a bore of 340 mm and stroke of 460. The engine will be capable of running on natural gas as an alternative to marine diesel oil, providing vessels with flexibility without major changes to the engine room or exhaust gas system, Cat said.
The company said that although it was designed for unlimited operation on LNG, marine diesel oil and heavy fuel oil, the M 46 DF will reach industry-leading efficiency in gas mode.
The new engine will go through customer acceptance tests and classification approvals in Rostock, Germany. Following trials, the M 34 DF will be sold through Caterpillar’s MaK dealer network. Initial deliveries are expected in October 2014.
