SeaMac provides full life cycle services for all our customers, from design to power system supply, from installation to commissioning, from after-sales service training to spare parts supply, from trouble shooting to overhaul technical support.
All of DCEC marine Main engine are comes with dry type exhaust system, which means dry type exhaust manifold and dry type turbocharger, SeaMac provides upgrading services for water-cooled exhaust system, which modify dry type exhaust system into water-cooled exhaust system, which are quite important and often requested by passenger boat projects.
Advantages of L8.9CMII313 Marine Engine
-
Leading design and excellent manufacturing technology make the engine more reliable and durable, suitable for high-strength, heavy-duty work under severe working conditions.
-
The cylinder block and cylinder head adopt integrated design to prevent the occurrence of engine water and oil leakage. The parts are about 40% less than other similar engines, and the failure rate is greatly reduced.
-
The cylinder bore adopts a platform mesh honing design, the perfect geometric structure effectively prevents oil leakage, and the use of advanced technologies such as new piston ring components and gasket crimping and molding 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.
