Car Craze

Many of the vehicles sold today either meet or are cleaner than federal low-emission vehicle standards. Automakers have managed to cut pollution in part by simply continually improving their skills in designing emission control. Car pollution remains a challenge as automotive engineers find ways to achieve refinement of emission reduction technique while industry leaders invent new technologies to create cleaner gasoline-powered cars.

The mixture of air and gasoline that is rapidly burned inside an engine’s cylinder is where exhaust pollution originates. If fuel is perfectly burned, the only by-products would be water vapor and carbon dioxide. In reality however, combustion is never perfect thus harmful pollutants such as unburned hydrocarbons, nitrogen oxides and carbon monoxide are created.
