Fuel Efficiency Analysis

Fuel consumption is measured under ISO 9249 standard operating conditions at 75% load over a 60-minute cycle. The Weichai WP-series engines feature high-pressure common rail (HPCR) injection and turbo-compounding technology, contributing to optimized combustion efficiency.

• U48-6: 18.5 L/h – Ideal for urban infrastructure with frequent start-stop cycles.
• U67-6: 26.3 L/h – Balanced efficiency for mid-range earthmoving tasks.
• U89-6 & U125-6: Consumption increases nonlinearly due to higher torque demands; however, specific fuel consumption (SFC) remains below 205 g/kWh, indicating industrial-grade efficiency.

Fleet managers should consider duty cycle patterns when selecting models. Continuous trenching or slope grading favors higher displacement engines with better thermal efficiency at sustained RPM.

---

Load Capacity and Axle Load Distribution

Axle load ratings are based on GVWR (Gross Vehicle Weight Rating) with full hydraulic arm extension and maximum bucket load. Reinforced rear axles and load-balancing frames ensure compliance with GB1589-2016 road transport regulations.

• Front/Rear Axle Distribution: Average 40/60 under full load, optimized for stability during swing operations.
• Tire Specifications (12.00R20): Radial construction with deep tread (28 mm), rated for 18-ply equivalent load index. Suitable for mixed terrain (paved, gravel, soft soil) with a maximum speed rating of 65 km/h.

Tire longevity averages 3,200–4,500 operating hours depending on ground conditions and load cycling frequency.

---

Operational Recommendations

1. Fleet Deployment: Use U48–U67 for municipal projects with restricted access; deploy U89–U125 for quarry and highway grading.
2. Maintenance Intervals: Weichai engines require oil analysis every 500 hours; HW19710 transmission fluid change at 1,000-hour intervals.
3. Fuel Strategy: Use ultra-low sulfur diesel (ULSD, <10 ppm) to maintain aftertreatment system integrity (DOC + SCR).

---

Conclusion

Kubota’s integration of Weichai powertrains and HW19710 transmissions in higher-tier excavator platforms delivers a competitive balance of fuel economy, load capacity, and durability. The standardized 12.00R20 tire specification ensures parts commonality across fleets, reducing downtime.
