Fuel Efficiency Analysis

Fuel economy in the observed WD615-powered truck fleet varies based on load profile and duty cycle:

• Loaded Highway (85% capacity): 3.2–3.8 km/L (7.5–8.9 MPG)
• On-Road/Off-Road Mixed (Construction Use): 2.6–3.1 km/L (6.1–7.3 MPG)
• Idling & Stop-Start (Urban Haul): 2.1–2.5 km/L (4.9–5.9 MPG)

The Weichai WD615 engine features high-pressure common rail (HPCR) injection and turbocharging, contributing to improved combustion efficiency over legacy mechanical injection systems. However, fuel efficiency is sensitive to maintenance intervals—soot-laden EGR systems and degraded injectors can reduce economy by up to 12%. Fleet operators report optimal efficiency when engine tuning is matched with HW19710 transmission shift mapping and tire pressure maintained at 100–110 psi.

---

Load Capacity & Operational Suitability

These trucks are routinely deployed in high-mass applications including:

• Aggregate hauling (gravel, sand, riprap)
• Pre-cast concrete transport
• Heavy equipment towing (lowboy operations)

With a standard GVWR of 40,000 kg and dual 13-ton rear axles, the platform supports payloads of up to 28,000–30,000 kg (61,700–66,100 lbs) depending on body configuration and front axle loading. The 12.00R20 tires, rated for 3,600 kg per tire at 110 psi, provide adequate ground contact and heat dissipation for sustained operation on Texas ranch roads and urban construction zones.

Fleet telemetry data from San Antonio-area operators indicates average utilization of 4,200 km/month with 78% of trips under 150 km—ideal for maximizing engine and drivetrain longevity under controlled conditions.

---

Recommendations for Fleet Integration

• Pre-Purchase Inspection Focus: Validate ECU logs for DPF/SCR tampering; inspect HW19710 shift forks and main shaft wear.
• Tire Maintenance: Monitor tread depth and casing integrity; 12.00R20 tires should be replaced at <4/32″ tread or visible cord exposure.
• Fuel Strategy: Use ultra-low sulfur diesel (ULSD) with cetane booster; avoid biodiesel blends >B5 unless engine firmware is updated.
• Load Optimization: Maximize payload efficiency by pairing with lightweight dump bodies or lowboy trailers to stay within legal axle limits.

This configuration offers a cost-effective solution for mid-tier hauling operations where initial acquisition cost and parts availability are prioritized without sacrificing core durability.

Best For	Operational vehicles, high-value fleets	Non-operational units, scrap or rebuild candidates	Oversized or non-roadworthy units with custom attachments

---

4. Corrosion Protection: Wax Spraying Protocol

Marine atmospheric salinity (avg. 35 g/kg NaCl) induces accelerated oxidation of ferrous components. To mitigate seawater-induced corrosion during transit, industrial-grade wax spraying is mandated across all shipping methods.

4.1 Wax Application Specifications

Parameter	Specification
Wax Type	Solvent-based, hydrophobic synthetic polymer (e.g., polyethylene wax emulsion)
Coating Thickness	25–40 µm (measured via eddy current gauge)
Application Method	High-pressure spray (2,000–3,000 psi), full undercarriage coverage
Target Zones	Frame rails, suspension mounts, fuel tanks, exhaust manifolds, wheel hubs
Drying Time	4–6 hours at 25°C ambient
Salt Spray Test Compliance	ASTM B117 – 500+ hours resistance (per ISO 9227)

4.2 Post-Transit De-waxing

• Solvent wash using biodegradable degreaser (alkaline-based, pH 9.5–10.5)
• High-pressure rinse (1,500 psi minimum) prior to commissioning
• Inspection for residual coating in brake and coupling interfaces

---

5. Method Recommendation Matrix

Use Case	Recommended Method	Rationale
Operational Fleets (Ready for Deployment)	RO-RO	Minimizes mechanical stress, fastest turnaround, ideal for drive-on/off destinations
Non-Operational or Damaged Units	Bulk Cargo	Cost-effective for non-revenue units; accepts higher risk for lower CAPEX logistics
Oversized or Modified Trucks (e.g., crane carriers, mixers)	Flat Rack	Accommodates non-standard dimensions; secure lashing points for irregular loads

---

6. Conclusion

For high-integrity export of used trucks from Chinese ports to global markets, RO-RO shipping offers optimal balance of protection, cost, and speed for operational units. Flat Rack is essential for non-standard configurations, while Bulk Cargo remains viable only for low-value, non-operational assets. Universal application of wax-based anti-corrosion treatment is non-negotiable to preserve residual vehicle value and meet international reconditioning standards.

SEA LION International recommends pre-shipment wax sealing at origin depots in China, integrated with method-specific lashing and stowage plans per IMO CSS Code (2022 Edition).
