Fuel Efficiency Analysis

Fuel consumption is measured under standardized load conditions (85–90% of max GVW) on mixed terrain (40% highway, 40% rural graded roads, 20% off-road inclines up to 8%).

• WD615.62 (266 HP): Achieves 3.0 km/L avg due to lower displacement (9.7L) and optimized gear mapping with HW19710. Ideal for regional haul and dump trucks.
• WD615.69/87 (336–371 HP): Consumes ~11.5–13.5 L/100km (2.5 km/L avg). Efficiency drops under continuous high-torque demand but offers superior gradeability.
• WD615.92C (420 HP): Highest fuel demand (~14.5 L/100km), but justified in heavy haul and mining applications where uptime and pulling power outweigh fuel cost per km.

Recommendation: For fleets prioritizing fuel economy, the WD615.69 paired with tire pressure monitoring systems (TPMS) and driver telematics yields up to 12% improvement in effective fuel utilization.

---

Load Capacity & Drivetrain Integration

The HW19710 transmission is a robust 10-speed manual gearbox designed for high input torque (up to 1,970 Nm), commonly mated to Weichai engines in 6×4 and 8×4 configurations. Its helical gear design reduces noise and wear under sustained load.

• Front Axle: Equipped with parabolic leaf springs and hydraulic dampers. Load range: 6,500–8,000 kg depending on reinforcement.
• Rear Tandem Axles: Use multi-leaf suspension with load-sharing differential locks. Rear capacity scales from 11,500 kg (standard) to 18,000 kg (reinforced housing + larger brakes).
• Tire Compatibility: 12.00R20 tires (18–22PR) provide optimal balance between ground clearance, load footprint, and resistance to sidewall damage on rough terrain. Load rating: 3,000–3,500 kg per tire at 850 kPa.

Max Payload Considerations:
– A 6×4 truck with WD615.87 engine and 12.00R20 tires can safely carry 40–45 metric tons on paved haul roads.
– For off-road applications (quarries, mine sites), axle load limits should be derated by 15% to prevent overheating and bearing failure.

---

Conclusion

The Weichai WD615 series, when paired with the HW19710 transmission and 12.00R20 high-load tires, remains a cost-effective solution for medium- to heavy-duty fleet operations. While newer platforms offer better emissions and fuel economy, the availability, repairability, and ruggedness of WD615-based powertrains make them ideal for high-utilization, low-downtime environments.

Fleet managers are advised to conduct pre-acquisition compression tests, injector flow balancing, and transmission wear inspections to ensure longevity in used units.

---

Executive Summary

This report evaluates three primary shipping methods—Roll-on/Roll-off (RO-RO), Bulk Cargo, and Flat Rack containers—for the export of used truck motors from Chinese ports (e.g., Shanghai, Qingdao, Guangzhou) to global destinations. Key performance indicators include cost efficiency, transit time, cargo protection, handling flexibility, and corrosion mitigation. Special emphasis is placed on wax-based anti-corrosion treatments to protect motors during marine transit.

---

1. Scope & Application

• Cargo Type: Used diesel truck motors (average weight: 800–1,200 kg/unit)
• Origin: Manufacturing and reconditioning hubs in Eastern and Southern China
• Destination: Emerging markets in Africa, Southeast Asia, Middle East, and Latin America
• Primary Concern: Long-term exposure to salt-laden marine environments during transit (7–28 days)

---

2. Shipping Method Comparison

Parameter	RO-RO (Roll-on/Roll-off)	Bulk Cargo (Loose Stowage)	Flat Rack Container (20′ or 40′)
Loading Mechanism	Self-propelled or towed onto vessel	Craned or forklift into hold	Lifted and secured on open-frame unit
Cargo Securing	Wheel chocks, tie-down straps	Wooden cradles, lashing, dunnage	Lashing points, steel straps, corner castings
Average Cost (USD/unit)	$380–$450	$290–$360	$520–$650
Transit Time	10–14 days (direct routes)	14–21 days (port congestion risk)	12–18 days (standard container routing)
Port Infrastructure	Requires RO-RO ramps (limited ports)	Universal (any bulk terminal)	Standard container terminals
Handling Risk	Low (minimal lifting)	High (multiple crane lifts)	Medium (requires secure lash)
Weather Exposure	Partial (internal vehicle deck)	High (open hold, humidity ingress)	High (fully exposed, unless covered)
Stackability	Not stackable	Not applicable	Single layer only
Best For	High-volume, time-sensitive shipments	Budget-sensitive, non-urgent consignments	Oversized or irregularly shaped motors

---

3. Corrosion Protection: Wax Spraying Protocol

Used truck motors are highly susceptible to saltwater-induced corrosion during maritime transport. SEA LION International mandates the following anti-corrosion procedure prior to shipment:

Wax-Based Corrosion Inhibitor Treatment (ASTM D1748 Compliant)

• Application Method: High-pressure spray (15–20 bar)
• Coverage Areas: Engine block, cylinder heads, exhaust manifolds, turbocharger housings, valve covers
• Recommended Product: Solvent-based, hydrophobic petroleum wax (e.g., Cosmoline VCI or equivalent)
• Film Thickness: 25–50 µm (uniform coating)
• Drying Time: 4–6 hours at 25°C prior to crating/loading
• Performance: Provides 6–12 months of protection under tropical marine conditions

Note: Wax treatment is mandatory for all Bulk Cargo and Flat Rack shipments. RO-RO units benefit from partial protection but still require internal cavity waxing (e.g., intake/exhaust ports sealed and treated).

---

4. Risk Assessment & Mitigation

Risk Factor	RO-RO	Bulk Cargo	Flat Rack	Mitigation Strategy
Seawater Corrosion	Medium	High	High	Wax spray + desiccants in voids
Physical Damage	Low	High	Medium	Steel cradles, edge protectors
Theft/Vandalism	Low	Medium	Medium	GPS-tagged units, port CCTV monitoring
Delays (Port Congestion)	Low	High	Medium	Pre-booked RO-RO slots; avoid monsoon seasons

---

5. Recommended Use Cases

Scenario	Recommended Method	Rationale
Export of 50+ motors to Lagos, Nigeria	RO-RO	Fast turnaround, reduced handling, partial environmental protection
Budget shipment to Jakarta, Indonesia	Bulk Cargo	Lowest cost; acceptable with full wax treatment and dunnage
Oversized mining truck engines (width > 2.5m)	Flat Rack	Only viable option for non-standard dimensions

---

6. Compliance & Certification

All shipments must comply with:
– IMSBC Code (for Bulk Cargo)
– CTU Code (Cargo Transport Unit – for Flat Rack)
– China Customs Export Declaration (Used Machinery)
– Fumigation Certificate (ISPM 15, if wooden cradles used)

---

7. Conclusion

For fleet managers and construction firms sourcing used truck motors from China, RO-RO offers the optimal balance of speed, safety, and partial environmental protection, especially when combined with industrial wax spraying. Bulk Cargo remains cost-effective for non-urgent, high-volume exports where budget constraints dominate. Flat Rack containers are essential for non-standard motors, though with elevated exposure risks requiring rigorous anti-corrosion protocols.

SEA LION International recommends integrated wax preservation across all methods and pre-shipment inspection per ISO 9001:2015 standards to ensure motor integrity upon delivery.
