Core Technology Support

Marine Engine Technology

High-strength engine block structures and efficient lubrication and cooling systems provide excellent durability and reliability; electronically controlled high-pressure common rail technology delivers robust power output and sufficient torque reserve to adapt to complex operating conditions; precise fuel injection control ensures low fuel consumption and meets environmental emission requirements; intelligent monitoring and sea state modes ensure safety and stability.

Safe and Reliable

High-strength engine block, crankshaft and connecting rods, high-flow pre-filter and post-cooling lubrication system, high-efficiency cooling system, simplified piping and single-cylinder-one-head design ensure reliable operation.

Powerful Performance

The electronically controlled high-pressure common rail system, turbocharger, fuel injector, and optimized intake port and combustion chamber matching maintain ample power and stable torque performance under various operating conditions.

Economical and Fuel-Efficient

The electronic control unit precisely regulates fuel injection timing and quantity, ensuring high air intake, complete combustion, and a wide range of economical operation.

Comfortable and Environmentally Friendly

Utilizes a high-pressure common rail system with ultra-high injection pressure, matched with a wastegate turbocharger to balance economy and emissions, providing a wide range of economical operation and low minimum specific fuel consumption.

High Practicality

LCD internet dashboard enables real-time monitoring of diesel engine speed, water temperature, oil temperature, and oil pressure; includes a wave mode to ensure the vessel does not shut down during critical moments such as encountering rough seas.
