The Facts on the MaK™ M 46 Dual Fuel Engine

With a bore of 460 millimeters and stroke of 610, the M 46 dual fuel engine was designed for electric drive propulsion systems as well as mechanical propulsion systems.

Although 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 M 46 DF was strategically engineered to allow for the retrofitting of current M 43 C engines. Additionally, existing M 32 C engines can be retrofitted to the MaK™ M 34 DF dual fuel platform. As a result of the synergies between the two platforms, Caterpillar can perform in hull retrofit conversions without having to move the engine block or perform extensive machining.
