How Can We Control Automobile Emissions Effectively?

Automobile emissions are one of the major contributors to air pollution, climate change, and public health risks. Gases like carbon monoxide (CO), nitrogen oxides (NOₓ), hydrocarbons (HC), carbon dioxide (CO₂), and particulate matter (PM) are emitted from vehicle exhausts, harming the environment and human lungs alike. As the number of vehicles on roads increases, it becomes crucial to understand how we can control automobile emissions through technology, regulations, fuel innovations, and personal behavior. At BM Process, our engineering solutions are deeply aligned with the global mission to reduce emissions—not only in industrial facilities but in transportation-related systems as well.

 

1. Use of Emission Control Devices in Vehicles

Modern vehicles are equipped with several devices to minimize harmful emissions:

  • Catalytic Converter – Converts CO, HC, and NOₓ into less harmful gases like CO₂, N₂, and water.
  • Exhaust Gas Recirculation (EGR) – Reduces NOₓ by recirculating exhaust gas into the engine.
  • Diesel Particulate Filter (DPF) – Traps soot and particulate matter in diesel engines.
  • Selective Catalytic Reduction (SCR) – Uses AdBlue (urea) to convert NOₓ into nitrogen and water vapor.
  • Evaporative Emission Control (EVAP) – Prevents fuel vapors from escaping into the atmosphere.

These technologies are mandatory in newer vehicles under Euro 6 and Bharat Stage VI emission norms.

2. Switch to Cleaner Fuels

Fuel quality plays a key role in controlling emissions. Consider:

  • Compressed Natural Gas (CNG): Burns cleaner than petrol or diesel, producing fewer NOₓ and PM.
  • Electric Vehicles (EVs): Produce zero tailpipe emissions and are ideal for cities with high pollution levels.
  • Biofuels (Ethanol, Biodiesel): Renewable and often emit less CO₂ than fossil fuels.

Cleaner fuels help reduce pollutants at the source and reduce the load on emission control devices.

3. Proper Vehicle Maintenance

Regular vehicle servicing and timely repairs can significantly reduce emissions:

  • Change air filters, oil, and spark plugs as recommended.
  • Ensure the fuel injection and ignition system are functioning properly.
  • Fix exhaust leaks and replace damaged emission control components.
  • Keep tire pressure optimal for fuel efficiency and reduced emissions.

A poorly maintained engine burns more fuel and releases more harmful gases.

 

4. Adopt Smart Driving Habits

Driver behavior has a direct impact on fuel consumption and emissions. To reduce pollution:

  • Avoid rapid acceleration and heavy braking.
  • Drive at consistent speeds and use cruise control when possible.
  • Turn off the engine during long idles (e.g., in traffic jams).
  • Shift gears efficiently in manual transmissions.

Eco-driving reduces fuel use and lowers CO₂ and NOₓ emissions.

 

5. Vehicle Scrappage and Upgradation

Older vehicles without modern emission technology pollute far more. Here’s what you can do:

  • Replace old petrol cars (over 15 years) or diesel vehicles (over 10 years) with newer, BS6-compliant models.
  • Take advantage of vehicle scrappage policies and government incentives for buying EVs or hybrids.

 

6. Follow Local Emission Standards and Inspections

In most countries, vehicles must pass periodic pollution checks:

  • Ensure your vehicle has a valid Pollution Under Control (PUC) certificate.
  • Comply with local and national emission norms like Euro 6 (Europe), Bharat Stage VI (India), or Tier 3 (USA).
  • Support and follow urban policies like low-emission zones or odd-even driving rules.

Refer to the European Environment Agency’s guidelines on vehicle-related emissions for more regulatory insight.

 

7. Encourage Public and Shared Transport

Reducing the number of personal vehicles on roads is one of the most effective emission control strategies:

  • Use metros, buses, trains, or carpools when possible.
  • Opt for cycling or walking for short distances.
  • Encourage ride-sharing apps and electric mobility solutions.

Fewer vehicles mean significantly lower urban air pollution.

 

Conclusion: Emission Control Is Everyone’s Responsibility

Understanding how we can control automobile emissions isn’t just about technology—it’s about daily choices. From adopting cleaner fuels and maintaining vehicles to switching to electric vehicles and supporting public transportation, both individuals and governments have a role to play. At BM Process, our expertise in emissions engineering spans industrial systems, automation, and regulatory consulting—ensuring a cleaner tomorrow through actionable solutions. Controlling vehicle emissions is not only essential for the environment but also for the future of public health and sustainable living.
