Question

The air pollution caused by the internal combustion engine vehicles can be reduced by using:
A. CNG gas
B. LPG
C. Petrol
D. Either $\left( A \right)$ or $\left( B \right)$

Answer 1

Hint: The air pollution caused by the internal combustion engine vehicles is due to the unburnt hydrocarbons, carbon monoxide, particulate matter, etc. In urban areas, this problem is increasing exponentially due to the increased use of vehicles. This can cause severe health problems to living beings and thus needs to be looked after really well.

Complete answer:
The increasing air pollution caused by the internal combustion engines has caused an exponential increase of ozone. Both LPG and are major causes of air pollution caused by internal combustion of vehicles which can be lowered down by using CNG gas or compressed natural gas which is a non-toxic fuel. When it is burned it leaves almost no residue as compared to other fossil fuels which is a blessing for the environment and also has high ignition temperature due to which there are less chances of a fire break out. Both petrol and liquid petroleum gas i.e., LPG produce very high carbon emissions and are harmful for the environment because they increase the amount of greenhouse gases in the environment. There are numerous advantages of using this gas, one of them is its power to increase the life of the vehicles because it causes little or no damage to the pipes and tubes of the vehicles.

So, the correct answer is “Option A”.

Note: Despite the numerous advantages that CNG gas has, it also possesses some disadvantages which include its limited availability in many areas due to which it cannot be extensively used in vehicles as a replacement of other fossil fuels. Another disadvantage is its high cost as compared to the other fuels.
