Product Features
- Fuel economy: The WP6 series marine diesel engine uses electronically-controlled fuel injection control, precise and flexible fuel injection timing control, fuel injection control and multiple injection technology which is able to efficiently reduce fuel consumption, emission and noise, and perfectly matches the diesel engine, significantly enhancing the comprehensive capability of the diesel engine in such aspects as power, fuel economy, emission and noise
- Reliable and durable: It uses the WP6's new second-generation engine block which, compared with the first-generation body, has aesthetic shape, is optimized with respect to its water port, and is able to reduce the engine oil temperature, and where the engine cooler and filter are integrated to obtain a compact and beautiful appearance.Due to further optimization and improvement of the oil sump, crankshaft, connecting rod, piston, piston ring and other components, the diesel engine becomes more reliable and durable.Through the CAE analysis and optimization of the main components, its service life is extended to 20000h
- Easy to maintain: The diesel engine uses a spin-on oil filter whose filter element is easy to replace. The oil filter and oil cooler are integrated into the engine block, so as to form a compact structure, increase the effective cooling area and reduce the oil temperature.It is easy and quick to replace the fuel filter element of the duplex filter without shutdown of the engine.The intercooler, heat exchanger, air filter, and fuel filter are arranged reasonably and easy to maintain
