Fuel Efficiency Analysis

The integration of the Weichai WD615 engine with optimized combustion tuning and the HW19710 transmission enables precise gear matching for variable load cycles. Under mixed operational profiles (digging, swinging, loading), the CAT 313 equivalent achieves:

• Average Fuel Consumption: 18–22 L/h (4.8–5.8 US gal/h)
• Idle Consumption: 4.2 L/h (1.1 US gal/h)
• Fuel Efficiency Gain: ~8–12% improvement over legacy mechanical engines due to improved volumetric efficiency and reduced parasitic losses.

The HW19710 transmission supports optimal engine load management through its wide gear spread (1.00:1 top gear, 12.86:1 1st gear), allowing operators to maintain RPM in the peak torque band during high-resistance digging or slope traversal, maximizing fuel economy under load.
