Reliable and Proven Marine Performance

The Weichai WH620 810–882 kW marine engine brings together advanced and reliable design features from multiple successful engine platforms. After passing a series of strict tests, the WH620 engine delivers stable and safe performance during long service at sea. In addition, Weichai’s global supplier network provides high-quality components, which helps the engine maintain strong reliability in daily operation.

Strong Power with Large Reserves

The Weichai WH620 810–882 kW marine engine uses an electronic-controlled combination pump and a four-valve cylinder head. These systems match fuel injection and airflow more accurately, giving the engine strong output and large torque reserves. As a result, the WH620 engine responds quickly and maintains solid power across a wide range of working conditions.

Fuel Efficient and Economical

The engine adopts electronic control and high-pressure direct injection technology. With more precise fuel delivery and more complete combustion, the WH620 marine engine runs with better fuel economy. This efficiency helps shipowners reduce operating costs while keeping reliable performance.

Smooth, Fast Response and Cleaner Operation

A pulse turbocharging system improves load response, allowing the engine to accelerate faster with lower smoke levels. Furthermore, the Weichai WH620 810–882 kW marine engine meets IMO Tier II and China Stage II emission standards, offering cleaner operation without losing power.

Compact, Practical, and Easy to Maintain

The WH620 marine engine features a compact structure and integrated component layout. Because of this design, the entire engine looks cleaner and is easier to use and maintain. Its simple arrangement also saves engine-room space and makes daily service more convenient for onboard crews.
