Question

One of the following is not a possible reason for use of CNG in automobiles
A.It can be adulterated
B. It is cheaper than petrol
C.It burns more efficiency
D.it reduces pollution

Answer 1

Hint: CNG is utilized in customary gas ignition motor cars that have been changed or in vehicles explicitly made for CNG use, either alone , with an isolated gas framework to broaden range (double fuel) or related to another fuel, for example, diesel.

Complete answer:
Let’s discuss the options and find out the correct answer
-Compressed natural gas- Vehicles require a larger amount of space for fuel storage than conventional gasoline-powered vehicles. Since it is a compressed gas, rather than a liquid like gasoline, CNG takes up more space for each GGE which is gasoline gallon equivalent.

-It is cheaper- CNG is also cheaper than petrol .This is an incorrect option.

-it burns more efficiency- Some CNG locomotives are able to selectively fire their cylinders only when there is a demand for power, which, theoretically, gives them a higher fuel efficiency than conventional diesel engines.This is an incorrect option.

-it reduces pollution-CNG emits less pollution directly than gasoline or oils combusted.And another advantage is it’s less carbon die oxide emission.So it help’s to reduce emission of greenhouse gases.Green house effect is the main reason for global warming.Therefore switching into CNG is better option in today's world.This is an incorrect option.
So the correct answer is (A) it can be adulterated.

Note: The tanks used to store the CNG take up space in the trunk of a car or bed of a pickup truck which has been modified to additionally run on CNG. This problem is solved in factory-built CNG vehicles that install the tanks under the body of the vehicle, leaving the trunk free which are sold in countries such as Peru)..
