Shipping vessels: such as inland cargo ships, bulk carriers, and oil tankers with a capacity of 500 tons or less, which are powered by main propulsion systems.
Fishery vessel: As the main engine of trawling vessels, fresh catch vessels and aquaculture vessels, it provides abundant and stable towing force.
Workship and passenger ship: suitable for port tugboat, traffic boat, patrol boat and small passenger ferry.
Auxiliary power: can be used as auxiliary engine for large ships, driving generator to supply power for onboard equipment
The structural design is reinforced: the engine adopts the second-generation reinforced body and gantry frame structure, which greatly improves the rigidity and can effectively cope with the complex stress and vibration during the ship navigation.
Key component upgrades: The engine's core moving parts, including the crankshaft, connecting rod, and pistons, have been comprehensively reinforced. Combined with an optimized lubrication and cooling system, this ensures a maintenance interval of up to 12,000 hours and a design life exceeding 20,000 hours, guaranteeing long-term reliability.
Extreme environmental adaptability: Excellent corrosion resistance and stable startup performance under varying water and ambient temperatures.
Intelligent electronic control management: Equipped with an advanced electronic control unit (ECU), it ensures precise control of fuel injection timing and quantity, featuring self-diagnosis and operational data logging to facilitate condition monitoring and maintenance.
Convenient maintenance: The system features a rotary oil filter and dual diesel coarse/fine filters that can be replaced without shutting down the engine, saving time and effort for routine maintenance. Most maintenance points are designed with user-friendly layouts for easy access..For more details about the WP6C220-23 marine engine, contact us Keluo Construction Machinery
