6LTAA8.9-GM200 Auxiliary Engine

DCEC 6LTAA8.9-GM200 marine auxiliary engine is a 6-cylinders in line, 8.9 liters four-strokes engine with 114 mm bore and 145mm stroke.

Equipped with BYC P7100 fuel pump and GAC electronic governor, engine comes with turbocharger and Air -Air Intercooler.

The prime power for generator set 1500 RPM of DCEC 6LTAA8.9-GM200 marine auxiliary engine is 200 kW.

DCEC provides both heat exchanger cooling and radiator cooling marine auxiliary engines, which mainly using for marine main generator and marine emergency generator.

For the emergency generator set applications, we provide additional options for customers such as dual starter motor system (we provide both electric and spring starter motor for customers), which are required by most of international classifications.

All of DCEC marine auxiliary 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 6LTAA8.9-GM200 Auxiliary Engine

Advanced design, exquisite manufacturing technology, reliable and durable, suitable for high-strength and heavy-duty operations under severe working conditions.
The integrated oil and water pipeline replaces the traditional hose, eliminating the hidden danger of leakage; the enhanced cooling and lubrication function effectively prolongs the service life of the engine.
The high-pressure common rail fuel system (HPCR) is adopted to ensure rapid throttle response at different speeds, better power and fuel economy, and lower noise.
Adopting exhaust gas bypass turbocharger, the supercharging is smoother at low speed, and the power output is more stable at high speed.
The engine back-end power output device (REPTO) can be used to enhance the control ability of remote equipment.
