Question

> Booju has two cars. In one car he uses petrol as fuel
and in second he uses CNG as fuel. Write which car
will make less pollution in environment. Why?
Explain.​

Answer 1

Answer:

Being a gaseous fuel, CNG mixes easily and evenly in air. CNG is less likely to ignite on hot surfaces, since it has a high auto-ignition temperature (540 °C), and a narrow range (5–15 percent) of flammability. CNG-powered vehicles are considered to be safer than petrol-powered vehicles.

Answer 2

Answer:

the CNG car will not pollute the environment.

Explanation:

It is because petrol cars emit smoke but cars which use LPG or CNG will not emit the smoke. Therefore the CNG car will not pollute the environment.
