Technical Highlights
Cummins DC air filtration system, which has a 35% smaller installation size than radial air filters, higher filtration efficiency, and a crankcase ventilation system equipped with a high-efficiency coalescing filter. The turbocharger (Holset HX40) has a twin-scroll design to ensure power stability in the hypoxic environment of the plateau, strengthen the crankshaft and connecting rod structure, and withstand frequent start-stop and vibration conditions.
Optimized for agricultural scenarios
PTO (power output shaft) efficiency ≥ 98%, ensuring efficient transmission of agricultural machinery. The dustproof seal design reduces the entry of straw and dust into the engine compartment.
The QSX15 agricultural motor has become the power benchmark for modern agricultural machinery through its three core advantages of low fuel consumption, high reliability, and all-terrain adaptability. Whether it is large-scale planting on the plains or special operations in the plateau mountains, it can provide long-lasting and stable power support to help increase agricultural production and efficiency.
