Weichai Injection pump assembly

High Reliability: The WP12 fuel injection pump assembly is built with a reinforced frame-type engine block and dry cylinder liner, ensuring durability and dependability. Extensive testing—over 45,000 hours on the bench and more than 50 million kilometers on the road—demonstrates its long-term reliability and robustness, making it a trusted choice for demanding applications.

Excellent NVH Performance: The engine's design incorporates a drum skirt and high-precision gears to significantly minimize mechanical noise. Combined with advanced multiple injection technology to reduce combustion noise, the WP12 engine achieves an idling noise level of just 81dB(A), which is 2-3dB(A) quieter than comparable products. This results in a more comfortable and quieter operating environment.

Ultra-Low Fuel Consumption: By utilizing high-efficiency components and optimizing the combustion process, the WP12 engine achieves a minimum fuel consumption rate of 179g/kW·h. Fuel consumption is reduced by 3%-5% under normal working conditions, especially in low-speed ranges (1000-1400r/min), making it highly economical and fuel-efficient.

Powerful Output: With a maximum torque of 2200N·m, the WP12 engine excels in providing strong power for various domestic working conditions. It offers impressive overtaking acceleration and climbing ability without needing to downshift, ensuring powerful performance in diverse scenarios.

Good Plateau Adaptability: The WP12 engine performs exceptionally well at high altitudes, showing no power reduction at 3500 meters and less than 5% power loss at 4100 meters. This adaptability makes it particularly suitable for use in plateau regions.

  In summary, the Weichai WP12 engine fuel injection pump assembly offers high reliability, excellent NVH performance, ultra-low fuel consumption, robust power output, and exceptional plateau adaptability, making it an efficient and reliable choice for various demanding conditions.
