A catalytic converter is an exhaust emission control device that reduces toxic gases and pollutants in exhaust gas from motor vehicle engines into less-toxic pollutants by catalyzing a redox reaction (an oxidation and a reduction reaction). Catalytic converters are used with gasoline and diesel-powered engines.
How can we reduce pollution caused by vehicles?
Everyone can take steps to reduce vehicle pollution
- Ride a bike or walk. If you are only going a short distance, consider riding a bike or walking instead of driving. …
- Take public transit. …
- Carpool. …
- Avoid idling. …
- Use alternative fuels.
Which device is used in air pollution control?
Existing air pollution control devices (APCDs) are capable of removing mercury to some extent, although most of them were not designed with this purpose. Existing APCDs include electrostatic precipitators (ESPs), fabric filters (FF or baghouse), flue gas desulfurization (FGD), and selective catalytic reduction (SCR).
What method of powering a vehicle will help to reduce air pollution?
Hydrogen fuel cell vehicles
Hydrogen-fueled vehicles emit virtually no hydrocarbons, particulates, carbon dioxide, or carbon monoxide. They are viewed as an especially attractive option for reducing green house gas emissions.
How can we minimize pollution?
On Days when High Particle Levels are Expected, Take these Extra Steps to Reduce Pollution:
- Reduce the number of trips you take in your car.
- Reduce or eliminate fireplace and wood stove use.
- Avoid burning leaves, trash, and other materials.
- Avoid using gas-powered lawn and garden equipment.
What are some examples of natural air pollution?
Naturally occurring pollutants include ash, soot, sulfur dioxide, ground-level ozone (also known as smog), salt spray, volcanic and combustion gases, and radon. These pollutants are released during volcanic eruptions, forest fires, and grass fires.
What air pollutants scare lungs?
Asbestosis—asbestos fibers cut and scar the lungs, causing difficulty in breathing.
What are employed for cleaning air?
Air-cleaners for particulates (suspension of fine solid or liquid particles in air such as dust, fog, fume, mist, smoke, or sprays) include: fabric collectors, centrifugal collectors, electrostatic precipitators, and.
Which fuel is polluted free?
CNG is also credited as being the cleanest burning fuel in the market today. CNG burns cleaner than petroleum based products because of its lower carbon content. It produces the fewest emissions of all other fuels and contains significantly less pollutants than gasoline.
How can public transport reduce air pollution?
Public transportation produces far fewer quantities of air pollutants, like carbon monoxide, carbon dioxide, and nitrogen oxides, per passenger mile. Public transit reduces the number of single occupancy vehicles on the road, which reduces the amount of pollutants entering the air.
How can Class 8 reduce air pollution?
An individual can reduce air pollution by: (i) Avoiding the use of cars as much as possible and by using public transport whenever possible. (ii) By not using vehicles for short distances. (iii) By using clean fuels such as LPG and CNG instead of diesel and petrol.
