Engine for transit buses WP12H

Low fuel consumption: Developed based on a 53.09% thermal efficiency diesel engine platform and supported by multiple proprietary technologies, it consumes 2 L/100 km less fuel than products in the same class.

Lightweight design: Lighter in the 11–12L displacement segment, weighing 150 kg less than products in the same class.

Excellent NVH performance: Employs technologies such as floating vibration isolation for the cylinder head cover, zero-backlash gears, and high-damping noise-reduction materials to achieve low noise in common speed ranges.

Powerful performance: Peak torque of 2000 N·m, leading in low-speed high-torque performance with fast transient response for stronger power delivery.
