Reciprocating internal combustion engines — Fire protection
1Key Takeaways
This document establishes requirements for reciprocating internal combustion engines to minimize the risk of fire caused by the engine, its components and the auxiliaries fitted to it. Where necessary, special requirements can be given for particular engine applications. This document applies to reciprocating internal …
2Expert Interpretation
An in-depth interpretation of ISO 6826:2022, the international standard for fire protection of internal combustion engines, covering 23 special requirement codes such as 30-minute fire protection test and high-pressure fuel system protection, and providing fire protection solution selection and implementation recommendations for different scenarios such as ships/agricultural machinery.
Analysis of the core requirements of the standard
| Protection category | Test conditions | Applicable components | Key parameters |
|---|---|---|---|
| 30 minutes fire test (A) | 800°C±50°C flame | Components containing flammable liquids | Zero leakage |
| 2.5 minutes fire test (B) | Free burning fuel | Fuel pipe system | ISO 7840 compliance |
| Flame retardant properties of plastic parts (C) | 5-second ignition test | Non-metallic components | Self-extinguishing time ≤5 seconds |
Key points of technological evolution and update
Main additions in the 2022 version:
- Applicable requirements for agricultural tractor/engineering machinery engines
- Supplementary provisions for flammable gas protection
- Exhaust aftertreatment system temperature monitoring (feature code N)
- Special requirements for explosion-proof crankcase of marine engine (feature code U)
Marine application case
Marine engines with a cylinder diameter ≥300mm must be equipped with:
- Crankcase explosion-proof pressure relief valve (feature code T)
- Oil mist detection device (feature code U)
- Double-wall fuel pipeline (feature code F)
Implementation recommendations
Basic compliance steps
| 1 | Check that the distance between all flammable liquid pipelines and high-temperature surfaces is ≥100mm |
| 2 | Confirm that the length of flexible pipelines is ≤1.5m and visible and inspectable |
| 3 | Provide a maintenance manual containing fire inspection procedures |
Special requirements selection matrix
| Application scenarios | Required feature code | Recommended feature code |
|---|---|---|
| Liquefied Natural Gas Engine | E(Static Electricity Protection) | C+P+Q |
| Mining Machinery | L(High Temperature Surface) | A+D |
