        Weichai WH28 series marine diesel engine (1650-2400kW)

        Product advantages

        The WH28 series diesel engine is a new generation of medium-speed diesel engine jointly developed by Weichai Group and Austria-based AVL, which is characterized by reliability, durability, strong power, energy saving and environmental friendliness, and easy operation.This series of engine models use a high injection pressure fuel system, and a high efficiency intake and exhaust system; it uses the Miller cycle in the operating process; its high strength bolts are tightened by means of hydraulic tensioning.The advanced design concept and design means ensure that the individual performance parameters of the diesel engine are at the international leading level.

        This series of engine models use modular, integration and serialization design concepts, with wide power range and adaptability, which can be widely used in fishing boats, offshore transport ships, large junks, public service ships, offshore engineering ships and for the power generator markets.It meets China Tier I and II and IMO Tier II emission requirements and has the potential to be upgraded to IMO Tier III.

        Product Features

      1. Reliable and durable: The safety factor of the shafting parts is above 1.3, which exceeds the allowable standard factor of 1.15 specified in the ship regulations, ensuring safety and reliability of the parts; the side pull bolts are arranged on the engine block to ensure the optimal stress distribution of the engine block, reduce the deformation of the parts and extend its service life.
      2. Strong power: It has a rated power of 2400kW, being about 15% higher than the similar competitive products; and a maximum combustion pressure of 220bar, being about 20% higher than similar competitive products; and is able to maintain maximum torque output at 70%-100% rated speed, obtaining a wide big-torque speed range.
      3. Energy-saving and Eco-friendly: The fuel injection pressure is up to 1500bar, the shape of intake port and combustion chamber is verified by simulation, optimization and test; the charging coefficient is up to 87%, reaching the international advanced level, the air intake is sufficient, and the fuel consumption rate is about 7% lower than the similar competitive products; the pulse supercharging system is provided to obtain good load responsiveness, fast acceleration, and low smoke density; the engine uses the Miller cycle to optimize the emission, meeting the IMO Tier II and China's Stage I and II emission requirements.
      4. Convenient operation: It uses a proven structure and modular design to achieve strong maintainability, and uses a three-section connecting rod so that it is convenient to lift the cylinder and easy to maintain and repair the engine, leading to less work load and time for maintenance.
