Cummins Marine 6BT5.9-GM100

The Cummins 6BT5.9-GM100 marine auxiliary engine is a 6-cylinder, in-line, 5.9-liter four-stroke engine with a 102mm bore and 120mm stroke. It is equipped with a BYC A fuel pump GAC electronic governor and a turbocharger. The prime power for the generator set at 1800RPM is 100kW.

Cummins Marine 6BT5.9-GM100 offers both heat exchanger and radiator cooling options for marine auxiliary engines, primarily used for marine main generators and marine emergency generators. For emergency generator set applications, additional options are available for customers such as a dual starter motor system, providing both electric and spring starter motors, which are required by most international classifications.

All DCEC marine auxiliary engines come with a dry-type exhaust system, including a dry-type exhaust manifold and turbocharger. we provide upgrading services for water-cooled exhaust systems, and modifying dry-type exhaust systems into water-cooled ones, which are important and often requested for passenger boat projects.

Advantages of the 6BT5.9-GM100

leading design and excellent manufacturing technology, making the engine more reliable and durable for high-strength, heavy-duty work under severe working conditions. The integrated design of the cylinder block and cylinder head reduces parts by about 40% compared to other similar engines, resulting in a significantly reduced failure rate.

The cylinder bore adopts a platform mesh honing design, effectively preventing oil leakage, while the use of advanced technologies such as new piston ring components and gasket crimping and molding further reduces oil loss. Synchronized with the advanced design and sophisticated manufacturing of CMS in the United States, it is suitable for harsh working conditions and has strong high-intensity, and heavy-duty operating capabilities.
