What are the common causes of engine sputtering in vehicles operating in Pakistan’s polluted urban areas?

Vehicles in Pakistani cities like Lahore and Karachi often face engine sputtering due to poor fuel quality, clogged air filters, and contaminated fuel injectors. Dust, smog, and heavy traffic conditions increase the strain on engines, leading to misfires and inconsistent performance. How can improved fuel standards and regular engine maintenance help reduce engine sputtering and associated emissions?

Engine sputtering in vehicles across Pakistan’s polluted cities is commonly caused by the use of poor-quality fuel, clogged air filters, and dirty o r malfunctioning fuel injectors. Dust and smog increase particulate matter in the air, which clogs air intake systems and reduces combustion efficiency. Additionally, inconsistent fuel quality leads to improper fuel-air mixtures, causing misfires and sputtering.

Improving fuel standards, ensuring regular replacement of air filters, and routine fuel system cleaning can significantly reduce sputtering. Government enforcement of cleaner fuel regulations and public awareness about vehicle maintenance are key to addressing this issue.
