... beneficial factors to promote public transportation in Cambodia is that it helps prevent the climate change from occurring in a very fast pace. That the vehicles produce smoke consisting of largely carbon dioxide (CO2) is widely known to the world, and its adverse effects to the environment are very critical. When there is more and more ... in the global warming because of the rising temperature that is caused by the "greenhouse" effect. The greenhouse effect is one of the greenhouse gases that result from carbon dioxide, and it acts as a blanket covering the earth to trap the tempe...

Problems calling us to action It is now common knowledge that carbon dioxide emissions from our vehicles add to the greenhouse effect. But have we ever stopped to ponder what the greenhouse effect is and what ... that comes from a decombustion engine that creates environmental problems. Other gaseous emissions that we don't normally hear about are Nitrogen Oxides (NOx), Sulfur Dioxide (SO2), Hydrocarbons (HC), and Carbon Monoxide. Each one of these gases has there own set of environmental problems that come along with it. Nitrogen Oxide and Nitrogen ... Dioxide are irritants to the lungs, w...

... different toxins that most are not even aware of. One main concern is the hydrocarbons that engines produce. Another production of cars is carbon dioxide; many do not realize the long term affects that CO2 can incur. Finally, a third hydrocarbon pollutant transpires through fuel evaporation in ... and it complicating respiratory problems. Hydrocarbons aren't the only pollutants released through car exhaust. Two more pollutants released through car exhaust are carbon monoxide and nitrogen oxide. The first reduces the flow of oxygen to the bloodstream, and could harm people with heart dis...

The truth, which many choose to ignore, is that SUV's can spew 30 percent more carbon monoxide and hydrocarbons with 75 percent more nitrogen oxides than passenger cars (Bradsher, 36). Americans disregard the truth because in America, a car is far more than just a means of transportation ... electric cars. Electric cars, according to the California Air Resource Board, compared to gasoline-powered vehicles, emit 98 percent less hydrocarbons, 89 percent less nitrogen dioxide, 99 pe...

... ) pollution produced from internal combustion engines powered by petroleum-based fuels. These engines "emit significant amounts of air pollutants, air toxins, and carbon dioxide. The health effects of these pollutants range from headaches to serious respiratory damage such as lung cancer" (Kushnir 12). Luckily, gasoline is not ... State University demonstrated this "minus-emissions" effect: When run on gasoline, the engine spews out high levels of pollutants, hydrocarbons, carbon monoxide, and nitrogen monoxide. But the same engine, when converted to run on hydrogen, actually reduces the...

... been implemented in order to combat this challenge such as the catalytic converter. A catalytic converter is a part of the exhaust system of the vehicle which turns carbon monoxide being produced by the engine into carbon dioxide which can be absorbed by surrounding greenery for photosynthesis. The modern day method of dealing with this in some cases is simply using half of what the ... ...

... . Pollution controls devices for cars have also been developed. For example, catalytic systems were installed in many car exhaust systems in the 1980s. These devices change dangerous gases into harmless carbon dioxide and water. They also burn up much of the exhaust with fresh air in a chamber near the exhaust pipe. The car of the future will need new designs which make ... ...
