Fuel Efficiency Analysis
Fuel economy for trucks equipped with the Weichai WD615 engine and HW19710 transmission is influenced by load profile, terrain, and driver behavior. In real-world operations across the Mid-Atlantic region (including Maryland’s I-95 corridor and rural haul routes), average fuel consumption is observed as follows:
- Loaded Highway (70,000 lbs GVW): 5.8–6.3 mpg (37.7–40.7 L/100km)
- Mixed Urban/Highway (Construction Duty): 4.5–5.2 mpg (45.6–52.0 L/100km)
- Idling & Off-Road Cycles: Fuel use increases by 8–12% due to prolonged PTO or engine idle
The WD615 engine’s electronic unit pump (EUP) system and optimized combustion chamber contribute to stable efficiency under variable loads. When paired with the HW19710’s close-ratio gearing, operators achieve smoother shift transitions and reduced RPM drop, enhancing fuel conservation during grade climbs.
Note: Retrofitting with auxiliary fuel monitoring systems (e.g., SAE J1939-based telematics) is recommended for fleet optimization.
Load Capacity & Operational Suitability
These trucks are engineered for high-cycle, heavy-load environments, making them ideal for:
- Aggregate and bulk material transport
- Heavy equipment hauling (lowboy applications)
- Longitudinal road construction projects along MD-295, I-68, and US-40
With a maximum payload capacity of ~50,000 lbs (after accounting for chassis and fuel weight), these units meet federal bridge formula requirements when properly configured. The twin 13-ton rear axles and robust ladder frame ensure minimal deflection under sustained loads.
The 12.00R20 tires provide a balance of load-bearing capability and road contact stability. At 18PR, they support up to 6,175 lbs per tire under dual-assembly conditions (SAE J1635), suitable for on/off-road transitions common in Maryland’s quarry and infrastructure zones.
Conclusion
