Cars account for half the oil consumed in the United States, about half the urban pollution, and one-forth the greenhouse gases. Carbon monoxide, nitrogen dioxide, particulates, and hydrocarbons are the main contributors to air pollution. ...
The question remains; who really invented the first car? ... There are many men who contributed their own ideas as to what the first car should look like and how it should run. But in truth, no man can admit that he solely invented the first car. ... However, there was also an increase in the amount of air pollution released into the atmosphere from the cars. This pollution problem was located in the internal combustion engine of the cars. Few people came to the realization that this engine "is the single largest source of air pollution in the United States".
In normal operation, a car burns fuel and emits the byproducts of the combustion process into the surrounding environment. ... If no emissions control equipment or adjustments are present in a car, then it will exhaust roughly 55% of hydrocarbon emissions and 100% carbon monoxide, nitrogen dioxide, and particulate emissions. ... A diesel-fueled car emits smaller percentages of hydrocarbons and carbon monoxide in its exhaust and has almost no hydrocarbon evaporative emissions. ... Therefore a few numbers cannot accurately represent the total emissions from all cars and other vehicles, but rough estimates of emissions from a "typical" car are possible.
Concern about the role of the car in air pollution first arose in southern California, because of its smog problem, in the late 1940s and early 1950s. ... Car emissions, along with industrial emissions and backyard burning, were identified as the major sources of the pollutants. ... This act set up by the EPA, was the first major step to reduce car emissions and toxic gases from being released into the atmosphere.
