Vehicle Emissions

Emissions from automobiles are one of the greatest contributing agents of air pollution in major cities across the globe. Driving a personal car is the most polluting activity of most citizens. Car emissions contain a range of many toxic pollutants such as sulphur dioxide, carbon monoxide, formaldehyde, nitrogen dioxide, benzene, and polycyclic hydrocarbons lead. Combustion Process A car is moved by burning fuel in an engine and its by-products are released in the combustion process into the surrounding environment. The by-products are released by the processes such as evaporative emissions, exhaust emissions, and refueling losses. Perfect Combustion: The fuels like diesel and gasoline contain hydrocarbons, which is a mixture and carbon and hydrogen atoms. In the perfect combustion process, the oxygen from the air converts the hydrogen from the fuel to water and carbon into carbon dioxide, thus nitrogen in the atmosphere is left undisturbed. But, in the real combustion … Continue reading Vehicle Emissions
