How does the lack of a proper exhaust gas recirculation EGR system affect the NOx emissions level in Changan Kalam in Pakistani markets?

Experts argue that absence o r failure of EGR increases nitrogen oxide output. Has Changan cut costs by omitting this component?

🛑 Lack o r failure of EGR leads to high NOx emissions.

The EGR system:

Recirculates exhaust gases to reduce combustion temperature

Helps lower nitrogen oxide NOx output

Changan Kalam may lack a functional EGR system o r it may be easily blocked by soot, reducing its effectiveness.

📛 High NOx contributes to smog and violates urban emission thresholds, especially in cities with poor air quality.
