Performance Analysis

Fuel Efficiency

Under mixed operating conditions (40% highway, 60% on-site/graded terrain), the WD615-powered configuration achieves an average fuel consumption of 28–32 L/100 km (8.3–7.3 US mpg). Fuel efficiency is optimized through:
– High-efficiency Bosch P-type fuel injection system
– Load-adaptive ECU tuning
– Low internal friction design in the HW19710 transmission

In consistent highway operation (loaded at 32,000 kg), fuel economy improves to 24–26 L/100 km (9.8–9.0 US mpg), demonstrating strong volumetric efficiency for a non-common-rail diesel platform.

Load Capacity & Operational Suitability

These trucks are engineered for heavy-volume, medium-to-long haul construction logistics, including:
– Aggregate transport (crushed stone, sand)
– Pre-cast concrete hauling
– Earthmoving support

With a payload capacity of up to 28,000 kg (61,728 lbs) on improved surfaces and full axle utilization, the platform supports high-density material transport. The dual 13-ton rear axles and robust 7-ton front axle provide stable load distribution, particularly on uneven terrain.

The 12.00R20 tires offer excellent cut and abrasion resistance, with proven performance in quarry and unpaved road environments. Their high load rating ensures minimal deflection under sustained GVWR operation, reducing heat buildup and tread wear.

---

Recommendations

• Ideal Use Case: Fleets engaged in regional construction supply chains requiring durable, high-torque trucks with proven mechanical reliability.
• Maintenance Note: WD615 engines require strict adherence to oil change intervals (every 15,000 km) due to EGR-free but high-soot operation.
• Upgrade Path: Consider retrofitting with auxiliary cooling modules for sustained uphill hauling or high-ambient-temperature regions.

This specification profile confirms the suitability of Blue Knob Auto’s Weichai-equipped units for cost-effective, high-utilization deployment in industrial transport sectors.

4. Corrosion Protection: Wax Spraying Technology

Marine environments expose steel substrates to salt-laden air and condensation, accelerating corrosion during transit—particularly in tropical and coastal zones.

Recommended Solution: Wax-Based Anti-Corrosion Spray

• Application: Full undercarriage, chassis rails, suspension components, and wheel arches.
• Product Type: Solvent-free, hydrophobic microcrystalline wax (e.g., Dinitrol AV-20, Corrosion X).
• Thickness: 150–200 µm dry film.
• Duration: Effective protection for up to 12 months in maritime conditions.
• Application Point: Pre-shipment at Blue Knob Auto prep facility or at port staging yard.

Benefits:

• Forms non-drying, self-healing barrier against saltwater ingress.
• Resists wash-off during rain or deck hosing.
• Compatible with painted and unpainted metal surfaces.
• No disassembly required—applied via high-pressure spray.

Engineering Recommendation: Wax spraying is mandatory for all export shipments, regardless of method. RO-RO units benefit most due to prolonged deck humidity; Flat Rack and Bulk Cargo units require full underbody coverage.
