Cars, trucks, and buses powered by fossil fuels are a major source of air pollution. In the US, transportation emits more than half of nitrogen oxides in the air and is a significant contributor to heat-trapping emissions. Vehicle exhaust has been linked to adverse impacts on health, with marginalized communities disproportionately affected by this pollution. To reduce emissions, people can opt for fuel-efficient vehicles, such as electric or hybrid cars, and maintain their vehicles by keeping up with regular tune-ups and oil changes. Additionally, driving habits can be adjusted to reduce pollution, including driving less, carpooling, and avoiding excessive idling.
What You'll Learn
Catalytic converters
The use of catalytic converters addresses the serious environmental concern of automobile exhaust pollution. They are an important tool in reducing the discharge of noxious gases from internal combustion engines, which contribute to air pollution and have adverse effects on the environment and human health.
Through these reduction reactions, catalytic converters can convert nitrogen oxides (NOx) into harmless nitrogen gas (N2) and water vapour (H2O). Carbon monoxide (CO) is oxidised and reduced into carbon dioxide (CO2), and hydrocarbons (HC) are oxidised into carbon dioxide and water (H2O).
The efficiency of catalytic converters depends on optimising temperature, gas flow, and composition. They work best at typical exhaust temperatures of around 300 to 600°C for gasoline engines. Colder exhaust temperatures result in slower reaction kinetics and lower conversion rates of pollutants. Gas flow patterns also play a role, as emissions must come into contact with the catalyst surface. Turbulent flow patterns increase the likelihood of this contact, improving reduction capability.
Overall, catalytic converters play a crucial role in reducing vehicle emissions and improving air quality and public health.

Cabin air filters
The Prana Air Car Cabin Air Filter is an example of a high-efficiency air filtration system that utilises both HEPA and activated carbon filters. It is designed to remove dust, pollen, allergens, and other airborne particles, providing a clean and healthy breathing environment for the vehicle's occupants. This filter is compatible with various car models and can be easily installed by following the provided instructions.
It is important to note that cabin air filters need to be replaced periodically, as they can get clogged over time. Most manufacturers recommend changing them after every 15,000 miles or once a year. However, this may vary depending on driving conditions and the level of pollution in the area. Regular replacement ensures that the cabin air filter continues to effectively purify the air and maintain a comfortable environment inside the vehicle.
Overall, cabin air filters play a crucial role in improving the air quality inside vehicles, reducing respiratory irritation, and enhancing the comfort and safety of the driver and passengers.

Proper vehicle maintenance
Follow the manufacturer's maintenance schedule: Regular tune-ups and services are crucial to keep your car in optimal condition. Follow the recommended schedule in your car's manual, and don't skip the recommended maintenance intervals. This proactive approach will help identify and fix any issues before they become more significant problems, reducing the risk of unexpected breakdowns and costly repairs.
Use the recommended motor oil and keep up with oil changes: Using the correct type of motor oil for your car is vital. Refer to your owner's manual or seek advice from a qualified automotive technician to ensure you're using the right oil. Regular oil changes are also essential for maintaining engine health and performance. Oil lubricates and protects your engine's internal components, and fresh oil helps to reduce friction and heat, leading to lower emissions and improved fuel efficiency.
Keep your tires properly inflated: Maintaining correct tire pressure is not just a safety precaution; it also improves fuel efficiency. Underinflated tires can increase rolling resistance, causing your engine to work harder and consume more fuel. Check your owner's manual for the recommended tire pressure and regularly monitor the pressure using a tire pressure gauge.
Regularly check your emissions control system: Modern vehicles are equipped with complex emission controls designed to minimize pollution. However, if any of these controls malfunction, your vehicle's emissions can increase significantly. Keep a close eye on warning lights, especially the "check engine" light, and have your car inspected by a qualified technician if any issues arise.
Reduce unnecessary idling: Idling vehicles contribute to air pollution and waste fuel. Avoid leaving your engine running when your car is stationary for extended periods. Contrary to popular belief, modern vehicles do not require prolonged idling to warm up, even in cold weather. Turn off your engine if you anticipate being stationary for more than a minute, as idling for extended periods can increase engine wear and tear.
Drive efficiently: Your driving habits can also impact pollution levels. Go easy on the accelerator and brakes, and maintain a steady speed whenever possible. Anticipate traffic flow and road conditions to avoid abrupt stops and rapid acceleration. Gradual acceleration and deceleration can help reduce fuel consumption and lower emissions.

Driving style
The way you drive can have a significant impact on the amount of pollution emitted by your vehicle. Here are some driving tips to reduce pollution and improve fuel efficiency:
Drive Efficiently
A smooth and controlled driving style can help reduce emissions and save fuel. Avoid aggressive acceleration and go easy on the gas pedal. Anticipate traffic flow and maintain a steady speed to minimise the need for sudden stops and starts. When coming to a stop, anticipate this in advance and coast to a halt, only using the brakes when necessary. This driving style will not only reduce emissions but also improve fuel efficiency and prolong the life of your brakes.
Speed Limits
Observing posted speed limits is not only safer but also more fuel-efficient. Driving at higher speeds burns more fuel and emits more pollutants. By adhering to speed limits, you can reduce your vehicle's emissions and fuel consumption.
Avoid Idling
Unnecessary idling wastes fuel and contributes to air pollution. Modern vehicles do not require prolonged idling to "warm up" in cold weather. Instead, it is recommended to drive gently until the engine reaches its optimal operating temperature. If you anticipate being stationary for more than a minute, turn off the engine to avoid unnecessary emissions and fuel consumption.
Maintenance
Regular vehicle maintenance is crucial for keeping your car running efficiently and reducing pollution. Follow the manufacturer's maintenance schedule, including tune-ups, oil changes, and tyre maintenance. Properly inflated tyres, for example, can improve fuel efficiency and reduce emissions. Additionally, ensure that any warning lights on your dashboard are addressed promptly by a qualified technician.
Alternative Transport
While not directly related to driving style, choosing alternative transport options can significantly reduce your environmental impact. Consider walking, biking, or using public transportation whenever possible. Carpooling and ride-sharing are also excellent ways to reduce the number of vehicles on the road and, consequently, overall emissions.
