Question

Explain how pollution has reduced by using CNG in our vechicles in our city

Answer 1

Combustion of fuels like petroleum causes formation of un-burnt carbon particles along with carbon monoxide gas. These harmful pollutants enter the air and cause respiratory diseases. Compressed Natural Gas (CNG) produces these harmful products in very less quantity. It is a comparatively cleaner fuel. Therefore, the use of CNG has reduced pollution in our cities.

Answer 2

Because cng is nature friendly and do not harm environment or cause much air pollution. but petrol and disel release a large amount of pollutants into air like sulphur dioxide, nitrogen dioxide etc that cause a great harm to environment. Air pollution cause less availability of fresh air to breathe and hence human life will be affected. If we use CNG we can help in reducing air pollution.
