Product Advantages
- Safe and reliable. Key components use high-quality Weichai suppliers and are developed according to the high reliability requirements of the marine engine industry.
- Has undergone bench test and high temperature, extreme cold and high altitude test verification to ensure the reliability of key components, with a whole-engine time between overhauls (TBO) of more than 8000h.
- Complete self-diagnosis system, complete failure-protection mode and safe control strategy.
- Fuel efficient. Uses an electronically controlled high-pressure common rail fuel injection system with precise control of injection pressure and injection timing, full fuel atomization and a wide economical fuel consumption range.
- Strong power. The control unit provides precise control, with high injection pressure, small speed fluctuation and strong power performance.
- Low-speed high-torque design with a large torque reserve, quick response and fast acceleration.
- Comfortable and eco-friendly. Whole-engine NVH optimization and matching, with noise-reduction designs such as the enclosed flywheel housing to reduce noise leakage.
- Uses electronically controlled multiple injection to greatly reduce vibration and noise.
- Water-jacketed exhaust manifold and exhaust tail pipe reduce the cabin temperature.
- Meets the emission standard of China non-road Stage IV.
- Highly practical. Optional configurations such as internet smart instruments and vibration damping pads meet different customer needs.
- Receives and outputs multiple control signals to meet automatic control requirements.
