Key Takeaways
- State the limit together with reference oxygen and test method
- Brochure figures are not universal project guarantees
- Retain engine, fuel, load and instrument conditions with every result
Technical guide introduction
An emissions number has meaning only with its pollutant, units, reference oxygen, dry/wet basis, temperature and pressure basis, test method, engine condition, fuel and stabilized operating point.

Six-Step Project Guide
Step 1
State the limit together with reference oxygen and test method
An emissions number has meaning only with its pollutant, units, reference oxygen, dry/wet basis, temperature and pressure basis, test method, engine condition, fuel and stabilized operating point.| Input to confirm | Guide context |
|---|---|
| State the limit together with reference oxygen and test method | Planning Guide |
| Brochure figures are not universal project guarantees | Project Planning |
| Retain engine, fuel, load and instrument conditions with every result | 12 minutes |
Step 2
Brochure figures are not universal project guarantees
The brochure cites NOx examples of 75 mg/Nm3 and a stricter 30 mg/Nm3 at 5% O2, with ammonia slip no more than 2.5 mg/Nm3. These are source references and require project-specific confirmation. State the limit together with reference oxygen and test method
Brochure figures are not universal project guarantees
Retain engine, fuel, load and instrument conditions with every result
Applicable regulation, permit condition, pollutant, limit and reporting authority
Engine model, rating, fuel, load range, annual hours and start/low-load profile
Engine-out concentration, exhaust flow, temperature, oxygen and particulate loading
Step 3
Retain engine, fuel, load and instrument conditions with every result
How to define limits, reference conditions, sampling, commissioning evidence and lifecycle records for exhaust and SCR projects.State the limit together with reference oxygen and test method
