6CTA8.3-M188 Marine Engine

DCEC 6CT8.3-M188 marine main engine is a 6-cylinders in line, 8.3 liters four-strokes engine with 114mm bore and 135mm stroke. Equipped with BYC PB fuel pump and R801 governor, engine comes with turbocharger and Water-Air Intercooler.

The prime power at 2328RPM of DCEC 6CT8.3-M188 marine main engine is 188 HP.

Based on standard DCEC marine main engines, SeaMac provides both heat exchanger cooling and keel cooling marine main engines, we also provide complete propulsion system that including marine engine, gearbox, shaft, propeller as complete power system. 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.

1. Advanced design, exquisite manufacturing technology, reliable and durable, suitable for high-strength and heavy-duty operations under severe working conditions.
2. Using high-pressure fuel pump, combustion is more complete under high fuel injection pressure, less energy loss, strong power, strong fuel adaptability, and lower emissions.
3. Adopt Holset supercharger with integral wastegate valve, low speed responsiveness and strong power.
4. Integral cylinder design, the number of parts is about 25% less than similar products, the failure rate is lower, and the maintenance is more convenient.
5. The cylinder liner adopts a platform mesh honing design and a corrosion-resistant high-nickel cast iron piston, which greatly reduces oil loss, enhances durability, and has a longer service life.
6. Advanced design, higher engine-to-liter power ratio, up to 23.4 kilowatts/liter.
7. The three-stage fuel filter ensures a balanced level of particle dispersion, protects the main components of the fuel system, and maximizes the life of the engine.
