Countermeasures to Automobile-Exhaust Pollution

Countermeasures to Automobile-Exhaust Pollution The world motor vehicle population exceeds 1 billion units at the moment. These vehicles are used for transportation of people and products across various places around the world. As a result, they emit many pollutants. This is attributable to the action of their engines burning fuel to release energy, which is an inefficient process. Firstly, they release particulate matter consisting of both organic and inorganic substances into the atmosphere, through exhaust emissions. Secondly, they release Volatile Organic Compounds (VOCs), which have carcinogenic effects. Pollution from vehicles is a universally acknowledged problem. However, it varies depending on the nation and its population. For example, pollution from cars contributes to between 50 to 90 percent of the total in urban areas. This may not be the same for rural areas. However, motor vehicles still present a disadvantage to the environment and human life. It is, therefore, prudent to develop countermeasures to automobile-exhaust pollution. Most of the world’s vehicles are operated on conventional hydrocarbons such as diesel and gasoline. By switching to fuel that maintains less pollution, the environmental impact of vehicles can be minimized. An alternative fuel technology that has the potential to meet this challenge is fuel cells. In this technology, hydrogen has maintained the best promise as a candidate to replace petroleum-based fuels. This technology utilizes hydrogen gas to create electricity. This electrical energy is converted to mechanical energy through an electric motor, which makes the wheels of an automobile to rotate. In this process, the emissions developed are pure water, Carbon (IV) Oxide and various oxides of nitrogen. This emissions are attributable to difficulties in storage and commercial production. Despite the release of oxides of carbon and nitrogen into the air, hydrogen fuel cells have a smaller footprint on the environment, when
