The M 32 C V-engine was introduced in 2000 in 12- and 16-cylinder versions. With a bore of 320 mm and a stroke of 460 mm, it covers a power range of 6,000 - 8,000 kW in the 720 and 750 rpm ranges. The engine is designed to meet not only the demands of the marine market but also those of the stationary electric power generation and oil & gas industry. The consistent application of the MaK long-stroke engine design and development along with the incorporation of as many in-line engine components as possible is clearly and impressively demonstrated in the external configuration - a compact, simple and clean design.

A compact, simple and clean design.

Designed to comply with current and future emission regulations the VM 32 C engine combines safety and operational reliability with fuel efficiency and long maintenance- and overhaul intervals. Component groups like the cylinder head or the dry engine block with its integrated coolant-, lube oil- and air ducts follow the modular engine design concept and do guarantee operator friendly service and maintenance through easy access to parts and components. The VM 32 C can be used in main propulsion as well as auxiliary applications and is designed to operate on MDO as well as HFO.

Low Emission Engine for low NOx

By combining increased compression ratio and the Miller effect, NOx emissions can be reduced by round about 30 % without sacrificing engine efficiency.

Outstanding Economical Operation

Reliable heavy fuel oil operation, low fuel and lubricating oil consumption, together with easy maintenance and long maintenance intervals, mean outstanding economical operation.

Flexible Camshaft Technology (FCT)

Building upon the emission reduction system integration concept, FCT achieves synergy between flexible fuel systems and advanced air systems with maximum utilization of the current engine design

Technically lower risk application of existing technology
