As one of the world’s leading engine manufacturers, Weichai continuously innovates to deliver high performance, fuel efficiency, and environmental friendliness. One of its most significant technological breakthroughs is the Electronic Common Rail Fuel Injection System — a technology now applied across most new-generation Weichai engines.

• Precise injection pressure control – Fuel is injected at extremely high pressure and with precise timing, ensuring complete combustion.
•  Optimized efficiency – reduced fuel consumption – Compared to traditional mechanical injection systems, Common Rail saves 10–15% fuel while increasing output power.
•  Smoother operation – reduced noise and vibration – Multi-stage injection improves engine stability and smoothness, protecting engine components.
•  Environmentally friendly – Common Rail technology significantly reduces NOx and particulate emissions, meeting today’s international emission standards.

The Common Rail system is currently applied on many of Weichai’s leading marine engines such as WP10, WP13, WP17T, and WHM6160, serving cargo vessels, tugboats, tourist boats, large fishing vessels, and various applications requiring durability, fuel efficiency, and continuous operation.

The Electronic Common Rail Fuel Injection System is not only a technical advancement but also a symbol of Weichai’s innovation capability and commitment to quality.
Thanks to this technology, Weichai continues to strengthen its position as a global pioneer in high-performance, eco-friendly marine engines.
