Cummins 6BTAA5.9-GM115

The Cummins 6BTAA5.9-GM115 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 PB fuel pump GAC electronic governor a turbocharger and an Air-Air Intercooler. The prime power for the generator set at 1500RPM is 115kW.

Cummins 6BTAA5.9-GM115 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 dry-type 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 6BTAA5.9-GM115 Auxiliary Engine:

1. The engine benefits from leading design and excellent manufacturing technology, enhancing reliability and durability. It is well-suited for high-strength, heavy-duty work under severe working conditions.
2. The engine features an integrated cylinder block and cylinder head design to prevent engine water and oil leakage. With approximately 40% fewer parts compared to other similar engines, the failure rate is greatly reduced.
3. Utilizing a platform mesh honing design, the cylinder bore achieves a perfect geometric structure that effectively prevents oil leakage. Advanced technologies such as new piston ring components and gasket crimping and molding further reduce oil loss.
4. The engine is synchronized with the advanced design and sophisticated manufacturing of CMS in the United States. This ensures suitability for harsh working conditions and provides strong high-intensity and heavy-duty operating capabilities.
