Cummins 6BTA5.9-GM120

The Cummins 6BTA5.9-GM120 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 a Water-Air Intercooler. The prime power for the generator set at 1800RPM is 120kW.

Cummins 6BTA5.9-GM120 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 6BTA5.9 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 quite important and often requested for passenger boat projects.

Advantages of the Cummins 6BTA5.9-GM120

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.
