Question

Least polluting fuel for vehicles is________

Answer 1

Compressed Natural Gas:

1. It is a non-corrosive and non-toxic gas that is colorless, odorless, and tasteless.
2. Natural gas, coal, bed methane, and oil wells are some sources of CNG.
3. When compared to other fuels such as petrol, diesel, and coal, it emits lesser hazardous chemicals into the atmosphere.
4. It is a biofuel that is less polluting than gasoline. Because the carbon content is lower, the amount of carbon in the atmosphere increases less.
5. As a result, the problem of global warming is mitigated to some extent.
6. It burns quickly and produces a lot of heat energy. Because it does not emit smoke, it is considered a clean fuel.

Therefore, Least polluting fuel for vehicles is Compressed Natural Gas(CNG).
