Green Your Car: Automobile Emissions and Pollution

Contrary to popular belief automobile emissions are not the largest contributor to global warming and climate change. However, the pollution and emissions from automobiles do make up about 1/3 of all emissions and are in fact the largest polluter in most large metropolitan cities.
For the average person, driving their car is the most polluting and damaging activity that they do. Cars emit a variety of different pollutants which have been know to cause cancer, acid rain, global warming and smog. Even though car companies have been forced to clean up the emissions, more people are driver longer distances making this effort have less of an impact.
Automobiles release pollution through evaporation and exhaust.
--Evaporation comes in a few different forms:
- Tank evaporation: liquid gasoline in a car’s gas tank is continually evaporating.
- Vaporization: when a car is on and the engine is hot, it vaporizes the gas.
- Vapor exchange: when refueling a car, the new fuel forces out the existing gas fumes.
--Exhaust from the internal combustion engine:
This is a result of the fuel not being burned completely. When hydrocarbon fuels are not completely burned, carbon monoxide, nitrogen oxides, unburned hydrocarbons and carbon dioxide are the result.
- Hydrocarbon emissions is basically the unburned fuel molecules that get released into the air and evaporate, causing smog (ground-level ozone).
- Nitrogen Oxide emissions area result of leftover oxygen under pressure than combines with nitrogen and creates NOx which is a major contributor for acid rain.
- Carbon Monoxide emission is another pollutant from incomplete combustion where the carbon in the fuel is only partially oxidized creating CO which is responsible for many different health issues. Finally there is Carbon Dioxide, otherwise known as “greenhouse gas”, although this emission is not poisonous, it is still a major problem.
- Carbon Dioxide has been building up in the earth’s atmosphere causing a layer of gas to form, that keeps more of the suns rays from escaping, thereby causing global warming.
Any Solution?
Fortunately, there are plenty of things you can do to help stop these pollutants from poisoning us and causing global warming. From having more efficient driving habits and using fuel catalyst and hydrogen add-ons, to buying hybrid, flex fuel and alternative energy vehicles, we can make a huge difference in our current emission.

I hope that some people are ready to go public with the research on HHO

Wrote an interesting post!! U have done nice piece of work.Thanks for sharing.
keep up the work.

Thanks for the informative post. Emissions from cars are a big enough contributor to the pollutants causing global warming. CFC pollutants from appliances such as refrigerators are now being under control because manufacturers are now using earth friendly alternatives. But we continue to drive cars that use harmful pollutants because the earth-friendly alternatives are more expensive. I have also heard that hybrid cars only decrease the amount of fuel consumption of the engine but do not prevent pollution in anyway because there are still emissions from such cars.

Man, I love cars and love driving. I just wish the movers and shakers on this planet would get their priorities right and really start developing environmentally friendly cars.

With the increased gas price, I’m sure people will drive less, or at least not drive much for pleasure which will take care of the emission a little
