Marine Propulsion Engines


The excellent reputation of the MaK brand is based on more than 80 years of experience in the development, manufacture, and service of diesel engines. MaK diesel engines feature a high level of reliability, low operating costs, simple installation and maintenance, and compliance with environmental emissions regulations. In addition to offering the right technology for emissions compliance for IMO Tier II and EPA Tier 2, Caterpillar offers options for performance improvement.

Flexible Camshaft Technology (FCT) achieves synergy between flexible fuel systems and advanced air systems while using current MaK engine design to its fullest. At part load, visible smoke is eliminated while performance and load pick-up are improved. Invisible smoke is a clear advantage for all applications.

The Cat Common Rail fuel system offers a direction for future regulatory compliance. This fully flexible fuel system handles the need for strict soot reduction. It uses injection maps, a technology to fine-tune injection characteristics for every engine operating point. Injection mapping guarantees optimum injection pressure and timing at a given load even in transient operation. As a result, both soot and NOx emissions are significantly reduced. The system permits vessel operation without visible soot throughout the entire operating range. Furthermore, during normal load, fuel consumption can be reduced without sacrificing NOx emissions. The Cat Common Rail system is suitable for Heavy Fuel Oil (HFO), Marine Diesel Oil (MDO), and Diesel Oil (DO) operations.

The current MaK product line is comprised of four medium-speed four-stroke diesel engine models ranging in power from 1,020 to 16,000 kW.
