WP14H Engine for Tractor

Reliability: Adopts a high-reliability system scheme and has undergone full-condition adaptability verification to ensure superior reliability. Comprehensive improvements to the engine block, pistons, and bearings, with a B10 life of 2.2 million km.

Economy: Positioned for long-haul standard-load tractors, with forward-developed adaptability for various working conditions; A product from a commercialized diesel engine platform with 53.09% thermal efficiency; Utilizes high-efficiency low-heat-transfer combustion technology, coordinated matching of air systems, high-compression-ratio and high-peak-pressure combustion chambers, high-precision injectors, and high-charge intake port design, among other high thermal efficiency engine technologies.

Power performance: Maximum torque of 2750 N·m, with the peak torque range extended down to 900 rpm, offering superior low-speed power. Through intelligent electronic-controlled turbocharging and precise turbocharger speed control, it combines high horsepower and large displacement with minimal high-altitude power loss and faster response, delivering power on demand in both steady and transient states.

Lightweight design: Modular design, featuring integrated fuel filter and integrated engine cooling/oil cooling module; Application of new materials, such as cast aluminum flywheel housing and high-strength plastic oil pan.

Comfort: Employs reinforced engine block design and vibration-isolation/noise-reduction technologies such as the floating design of the cylinder head cover and plastic oil pan to further reduce vibration and noise, achieving levels 2–3 dB(A) lower than comparable products.
