What percentage of air pollution is caused by vehicles?
What percentage of air pollution is caused by vehicles? The Environmental Protection Agency estimates that vehicles cause nearly 75 percent of the carbon monoxide pollution in the United States.
What causes emission problems in a car?
Ignition defects including dirty spark plugs , leaking or open-circuited spark plugs or wires, or defective ignition coils can all result in a shortage of spark energy. Any shortage of spark energy may cause high HC emissions. If the spark occurs at the wrong time, incomplete combustion and high hydrocarbons may result.
How much pollution do cars cause?
