Weichai cylinder head assembly

High Reliability: The Weichai WP12 cylinder head assembly is engineered for exceptional durability and stability. Its robust frame-type body design and dry cylinder liner enhance the engine's reliability. Extensive testing has validated its performance: over 45,000 hours of bench testing and more than 50 million kilometers of road testing confirm its resilience and long-term operational stability. This rigorous validation ensures that the cylinder head can withstand the rigors of heavy-duty use.

Excellent NVH Performance: This cylinder head assembly delivers superior NVH performance, crucial for a quieter and more comfortable user experience. It achieves an idling noise level of just 81 dB(A), which is 2-3 dB(A) lower than comparable products. This reduction is due to the innovative drum-shaped skirt design, high-precision gears, and advanced shearing gears in the rear gear chamber. The incorporation of multiple injection technology further diminishes combustion noise, ensuring a quieter operation and enhanced user comfort.

Ultra-Low Fuel Consumption: Weichai’s WP12 cylinder head assembly demonstrates impressive fuel efficiency. It boasts a minimum fuel consumption rate of 179 g/kW·h, outperforming similar products by 3%-5% in common operating conditions, particularly in the low-speed range (1,000-1,400 RPM). This efficiency is achieved through optimized combustion processes, a refined camshaft profile, and high-efficiency superchargers.

Strong Power Output: With a maximum torque of 2,200 N·m, the Weichai WP12 cylinder head assembly provides robust power delivery. Its excellent acceleration performance and ability to handle inclines without downshifting ensure reliable and efficient operation in diverse scenarios.

Environmental Adaptability: The cylinder head assembly maintains performance at high altitudes, experiencing less than 5% power loss at 4,100 meters, making it highly suitable for plateau environments.

In summary, the Weichai WP12 cylinder head assembly offers unparalleled reliability, comfort, fuel efficiency, and power, ensuring optimal engine performance across various operational conditions.
