6LTAA8.9-M315 Medium-sized Ship Marine Engine

The 6LTAA8.9-M315 marine engine is designed for medium-sized ships. It combines modular engineering concepts with intelligent emission control technology and is suitable for offshore fishing, inland river transportation and sightseeing yachts. Its unique split cylinder head design allows for quick maintenance of key components without disassembling the entire machine, greatly shortening the maintenance cycle. Combined with a closed-loop electronically controlled cooling system, it can dynamically adjust the water temperature according to the load, reduce cold start wear, and extend the life of the engine.

Key parameters of the 6LTAA8.9-M315 medium-sized ship marine engine:
‌Power output‌: 315 horsepower @ 2300 RPM (peak torque 1250 N·m @ 1600 RPM).
‌Fuel adaptability‌: supports diesel/biodiesel mixed fuel.
‌Emission standards‌: IMO Tier II / EPA Tier 3, integrated SCR aftertreatment (nitrogen oxides reduced by 85%).
‌Structural optimization‌: Aluminum alloy intercooler + cast iron cylinder block composite structure, 15% lighter and more corrosion resistant.
‌Intelligent management‌: Built-in i-Power 2.0 diagnostic interface, supports remote real-time monitoring of fuel efficiency and cylinder balance.

For operating environments with frequent starts and stops (such as port tugboats and short-distance ferries), the engine is equipped with the "Eco-Cruise" intelligent cruise mode, which learns sailing habits through algorithms, automatically optimizes throttle response, and saves 8%-12% of fuel in actual measurements. In addition, its compact layout (length × width × height: 1.2m × 0.9m × 1.05m) is suitable for dual-engine installation solutions, providing redundant power guarantee for catamarans.
