Reliable and Safe for Marine Work

The Weichai CW250 1103–1960 kW marine engine gives ships steady and secure power during long service at sea. This CW250 engine uses a strong block, crankshaft, and connecting rod structure. These high-strength parts raise the safety margin and keep the engine stable under heavy load. With this solid design, the engine delivers reliable performance through long working hours.

Strong Power with Fast Response

The Weichai CW250 1103–1960 kW marine engine covers a wide power range and keeps strong torque at all speeds. Its high-pressure fuel pump, turbocharger, injector, and valves work together in a well-matched system. Because of this coordination, the engine builds torque quickly and reacts fast during low-speed use. It also accelerates smoothly when the vessel needs more power.

Users can choose a twin-turbo setup as well. With this option, the engine lifts low-speed torque by as much as 30 percent. As a result, the CW250 engine responds even faster, pushes harder at low rpm, and also helps lower fuel use during daily operation.

Fuel Saving and High Efficiency

The engine uses four-valve technology and pulse turbocharging to bring in more air and support full combustion. With better airflow, the Weichai CW250 engine keeps fuel consumption low, reaching about 200 g/kW·h at best. This level of efficiency helps shipowners cut daily operating costs while still keeping strong output.

Smooth, Quiet, and Environment-Friendly

A stiff damper with a leaf-spring layout reduces vibration and noise, so the engine runs more smoothly and keeps the working space more comfortable. The CW250 marine engine also meets IMO Tier II and China Stage I emission rules, allowing cleaner operation with steady performance.

Practical and Easy to Match

The CW250 marine engine offers flexible turbocharger placement. Owners can place the turbocharger on either the free end or the flywheel end, so it fits different vessel designs more easily. This flexibility also makes installation and layout planning more convenient.
