Reliable Design for Long Marine Service

The Weichai WP10 205–290 kW marine engine uses a high-strength block, pistons, and bearings to stay reliable under high explosion pressure. In addition, Weichai’s global supplier system ensures stable and trusted quality for every key part. The engine also passes strict durability tests, allowing it to reach an overhaul interval of more than 20,000 hours. Moreover, its self-check program, full protection modes, and safe control strategy help crews operate 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 fluctuations low. Because of this, the WP10 delivers strong power and smooth output in daily operation. Furthermore, the low-speed, high-torque layout offers a torque reserve of 20%–35%, giving fast response during load changes and quick acceleration when needed.

Fuel-Saving and Cost-Effective

The WP10 uses an optimized injection pattern that adjusts injection pressure, volume, and timing with great precision. As a result, the fuel atomizes more fully, helping the engine run with higher efficiency. The fuel consumption rate can reach 190 g/kW·h, which lowers operating cost and supports long working cycles at sea.

Smooth, Quiet, and Cleaner Operation

With multi-stage injection—including pilot and post injection—the engine reduces 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 WP10 meets IMO Tier II, China Stage I, and China Stage II emission standards, offering cleaner and more comfortable performance.

Practical, Flexible, and Easy to Integrate

The WP10 supports 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 help reduce engine height, which makes engine-room layout easier. The control system can also switch strategies based on different performance needs, and it supports many input and output signals for marine automation. Because of these features, the WP10 fits well in fishing boats, transport vessels, small engineering vessels, and marine generator sets.
