Reliable Marine Performance

The Weichai 6WH28 2050–2700 kW marine engine offers stable and safe power for vessels working in demanding sea conditions. This 6WH28 marine engine uses a high-strength block with side-pull bolts that control stress more evenly and raise long-term durability. Supported by Weichai’s global supply network, the engine benefits from steady, high-quality parts. A clean and temperature-controlled assembly line, together with accurate testing stations, further improves build quality and ensures consistent performance during long voyages.

Strong Power and Fast Response

The Weichai 6WH28 2050–2700 kW marine engine delivers strong output for mid-to-large ships. It reaches high explosion pressure and provides faster low-speed response compared with many engines in the same class. With an efficient turbocharging system, the 6WH28 engine increases low-speed torque reserves, giving ships smoother acceleration and better control in narrow waters or heavy-duty working conditions. This power range suits cargo vessels, workboats, offshore supply ships, and other applications that need both strength and stability.

Lower Fuel Use and Cleaner Operation

High-pressure injection and an efficient intake and exhaust layout help the engine achieve low fuel consumption. Its optimized combustion and pulse turbocharging design aim to keep the rate near industry-leading levels. A three-ring piston structure, working with a scraper ring, reduces lube oil use and helps keep the engine clean over long hours of work. The 6WH28 marine engine meets IMO Tier II and China Stage II emission rules, so ships can operate with lower impact on the environment.

Simple Service and Easy Control

A modular layout and mature mechanical design make daily service easier. The three-section connecting rod lowers the working height and allows faster cylinder handling. The engine also offers a clear human-machine interface with a touch-screen panel, giving crews simple, direct access to key operating data. These features help reduce downtime and improve overall reliability during long-term marine operation.
