Reliable Design for Long Marine Service

The Weichai WP13 330–405 kW marine engine uses a high-strength block, piston, and bearing design to stay reliable even under high explosion pressure. In addition, Weichai’s global supplier network provides steady and trusted quality for all key parts. The engine also passes strict durability tests, so it can reach an overhaul interval of more than 20,000 hours. Moreover, its built-in self-check system, protection modes, and safe control strategy help crews run the engine with confidence.

Strong Power and Quick Response

The electronic control unit manages fuel injection with high accuracy, which keeps injection pressure high and speed changes small. Because of this design, the WP13 delivers strong power and smooth output. Furthermore, the low-speed, high-torque layout gives the engine a torque reserve of 25%–35%, allowing fast response and quick acceleration in many working conditions.

Fuel-Saving and Cost-Effective

The WP13 marine engine uses an optimized injection pattern that adjusts pressure, volume, and timing with great precision. As a result, the fuel burns more fully and the engine runs more efficiently. Its minimum fuel consumption rate reaches 192 g/kW·h, which helps reduce daily operating cost during long trips.

Smooth, Quiet, and Cleaner Operation

With multi-stage injection—such as pilot and post injection—the engine lowers noise and vibration by up to 20% compared with mechanical pump systems. At the same time, its water-cooled exhaust manifold and tailpipe help reduce engine-room temperature. Moreover, the WP13 meets IMO Tier II, China Stage I, and China Stage II emission rules, offering clean and steady performance.

Practical, Flexible, and Easy to Integrate

The WP13 offers optional LCD smart gauges, vibration pads, and a hand-pump system to meet different customer needs. In addition, a horizontal air filter and rear-mounted turbocharger reduce engine height, which makes engine-room layout easier. The control system can also switch strategies to match different performance needs, and it supports many input and output signals for marine automation.
