Weichai Fuel injector assembly

  The Weichai WP12 engine fuel injector assembly is engineered to deliver outstanding performance across a range of demanding conditions, featuring key advantages in reliability, NVH (Noise, Vibration, and Harshness) performance, fuel efficiency, power output, and plateau adaptability.

High Reliability: The WP12 injector assembly benefits from a frame-type body and a dry cylinder liner, coupled with a highly reinforced engine design. Rigorous testing—including over 45,000 hours of bench testing and more than 50 million kilometers of vehicle road testing—confirms its durability and consistent performance, making it a reliable choice for diverse applications.

Excellent NVH Performance: The injector assembly incorporates a drum skirt design, along with a rear gear chamber and high-precision gears, to effectively minimize idle noise. With an idle noise level of just 81dB(A), it is 2-3dB(A) quieter than comparable products. Multiple injection technology further reduces combustion noise, enhancing the overall driving experience by providing a quieter and more comfortable environment.

Ultra-Low Fuel Consumption: The WP12 injector assembly excels in fuel efficiency due to its use of high-efficiency components and an optimized combustion process. It achieves a fuel consumption rate that is 3%-5% lower than similar products, particularly in low-speed conditions (1000-1400r/min). This efficiency translates to significant cost savings and makes the engine more economical to operate.

Strong Power Performance: With a maximum torque of 2200N·m, the WP12 engine offers exceptional power output suitable for various domestic working conditions. It provides superior acceleration and climbing ability without the need to downshift, ensuring efficient performance across different tasks.

Good Plateau Adaptability: The injector assembly performs reliably even at high altitudes, with no power reduction at 3,500 meters and less than 5% power loss at 4,100 meters. This adaptability makes it well-suited for operation in challenging plateau environments.

  In summary, the Weichai WP12 engine fuel injector assembly provides high reliability, excellent NVH performance, ultra-low fuel consumption, strong power output, and impressive plateau adaptability, making it a robust and efficient solution for a wide range of applications.
