Emergency Fuel Delivery Service

1. Definition and Applicable Scenarios

Emergency fuel delivery refers to a roadside assistance service where, when a vehicle's fuel gauge drops to empty and the estimated remaining driving range is insufficient to reach the nearest petrol station, a professional recovery team dispatches a service vehicle to deliver emergency fuel on-site, allowing the stranded vehicle to resume its journey. The primary objective is to resolve non-mechanical breakdowns caused by fuel starvation at the lowest time cost, preventing traffic congestion and roadside safety hazards.

Common scenarios include: running out of fuel due to neglecting fuel level monitoring during long-distance driving; failing to refuel as planned due to extended distances between highway rest and service areas (R&R) or temporary station closures; inaccurate fuel gauge readings caused by faulty fuel level sensors; and mileage miscalculations due to sparse petrol station networks in remote areas.

2. Operational Modes and Procedures

• Phase 1: Location Tracking and Fuel Grade Verification

  • Service dispatchers pinpoint the vehicle's exact location via GPS coordinates, verify the nearest petrol station, and map out the subsequent refuelling route.

  • Confirm the required fuel grade with the vehicle owner: petrol is classified into RON 92, RON 95, and RON 98 (Research Octane Number); diesel is graded based on cold flow properties (such as 0#, -10#, -35#, depending on climatic regions). Misfuelling will cause severe engine damage, requiring double-confirmation by the roadside assistance team prior to dispatch.

• Phase 2: Delivery Methods

• Phase 3: Refuelling and Engine Start-up Verification

  • Manual refuelling via jerry can must utilise a dedicated spout or funnel to avoid fuel spillage onto hot exhaust manifolds, pipes, or the catalytic converter.

  • Once refuelled, the technician assists the driver with the initial engine start-up. As running the fuel tank dry often introduces air into the fuel lines, switch the ignition to 'ON' for 3–5 seconds before cranking to 'START'; repeat 1–2 times to prime the system and purge trapped air until the engine idles smoothly.

  • Advise the driver to proceed immediately to the nearest petrol station to fill up, rather than continuing a long journey on emergency fuel alone.

3. Safety Standards and Risk Mitigation

• Anti-Static Measures: The rescue vehicle's engine must be switched off throughout the refuelling process. Technicians must touch an unpainted metal section of the car body to discharge static electricity before handling fuel containers or nozzles. Mobile phone use is strictly prohibited within the work perimeter (while RF radiation from calls rarely ignites vapours, micro-sparks from physical button toggles or cable connections and potential battery short circuits pose real ignition hazards).

• Container Compliance: Portable fuel containers must comply with national fuel storage and transport standards (such as GB 19147 for diesel and GB 17930 for petrol), utilising explosion-proof jerry cans made of metal or high-density polyethylene (HDPE) with built-in spouts and automatic pressure-relief valves. The use of glass bottles, PET mineral water bottles, or regular plastic pails is strictly prohibited, as non-conductive containers build up static charge during filling that cannot dissipate, posing severe flash-fire and explosion risks.

• Naked Flame Exclusion Zone: Smoking, open flames, and heat-generating equipment are strictly banned within a 10-metre radius of the refuelling zone.

4. Fee Structure and Service Scope

Service Limitations:

• Emergency fuel delivery strictly covers fuel starvation. If the vehicle fails to start due to mechanical faults (such as a faulty fuel pump, clogged fuel injectors, or ignition failure), the case falls outside fuel assistance and must be converted to a tow truck service.

• Under complimentary roadside assistance bundled with comprehensive motor insurance policies, usually only the call-out service fee is waived, while the fuel supplied must be paid for at retail price. Annual complimentary requests are typically capped at 2–3 times, with subsequent requests charged at standard rates.

• Certain highway concessionaires prohibit third-party recovery vehicles from conducting roadside refuelling on expressways. In such instances, the highway patrol/auxiliary recovery unit will attend to the vehicle, with charges regulated by local transport authorities.

5. New Energy Alternative — Mobile EV Rescue Charging

The EV equivalent of emergency fuel delivery is mobile EV charging assistance, both serving as on-demand emergency energy top-ups:

6. Industry Trends

• Smart Cruising Range Alerts: In-car navigation systems analyse real-time fuel/energy consumption algorithms, upcoming road gradients, and petrol station density, proactively routing drivers to the nearest petrol station or EV charger when the range drops below 80 km, eliminating fuel run-out incidents at the source.

• Drone-Assisted Fuel Drops: In remote mountain passes or heavily congested highway gridlocks, heavy-payload industrial drones (5–10 kg capacity) can air-drop portable fuel containers directly to stranded motorists, cutting waiting times by over 50% compared to road-based dispatch.

• Dual-Power Service Fleets: Next-generation roadside recovery vehicles carry both emergency fuel supplies (10L) and mobile battery energy storage systems (approx. 15 kWh), allowing a single fleet unit to service both conventional ICE vehicles and electric vehicles efficiently.
