Shop Dongfeng Cummins 6CT8.3-M220 Marine Diesel Engine Assembly | Tonkee®

At the heart of the 6CT8.3-M220 is a 6-cylinder, turbocharged, and aftercooled diesel engine.

The engine displacement of 8.3 liters ensures a balanced blend of power and fuel efficiency. Its advanced design incorporates electronic control systems to optimize combustion, ensuring precise fuel delivery and reducing emissions to comply with stringent marine emissions standards.

The engine's power output is rated at 220 horsepower (163 kW), making it suitable for a wide range of marine vessels, including commercial ships, fishing boats, and workboats. Its torque delivery across a broad range of RPMs ensures ample power for acceleration, maneuvering, and hauling tasks while maintaining fuel efficiency.

The assembly's cooling system is engineered to handle the demanding conditions of marine environments. A seawater-cooled heat exchanger efficiently dissipates heat, while the integrated freshwater cooling system prevents corrosion and maintains optimal engine temperature.

To ensure reliable operation, the 6CT8.3-M220 features robust construction and high-quality components.

The engine block, cylinder heads, and crankshaft are designed to withstand the rigors of continuous marine use. Additionally, the engine's components are built to minimize maintenance requirements, reducing downtime and operational costs for marine operators.

The electronic control module (ECM) manages various engine functions, including fuel injection timing, air-fuel ratio, and emissions control. This ECM also facilitates diagnostic capabilities, enabling onboard monitoring and troubleshooting, thereby enhancing overall operational efficiency and reducing the need for extensive manual intervention.

With an eye toward environmental responsibility, the engine incorporates technologies to reduce emissions and promote cleaner combustion. This is achieved through a combination of advanced fuel injection systems, exhaust gas recirculation (EGR), and selective catalytic reduction (SCR) systems.
