Question

Mention two advantages for preferring CNG over diesel as an automobile fuel.

Answer 1

Hint: CNG is the natural gas and made from the combination of the compressing natural gas that is obtained from the methane composition and less than 1% of the volume at the standard pressure. CNG pressure of 200-280 bars and stored in the hard cylinder. It is cheaper than fuels, dispersed easily when it is released, lighter than the air and releases less carbon dioxide in the atmosphere is the main importance of the CNG gas.

Complete answer:
The CNG gas lead to the fouling of spark plug and eliminated due to the absence of the benzene and lead, and in the vehicles maintained the low cost, life of the lubricants increases, easily mixed in the air, and have high auto ignition temperature 540 degree and small range of flammability 5% to 15% in the hot surface where it is less likely, and more efficiency but produced less pollution. And the main two advantages of the CNG are:-
-CNG Locomotives: - in the year 2002 the first locomotive train successfully retrofit a diesel locomotive run on compressed natural gas is known as the name the Napa valley wine train. CNG Locomotive on a freight line since in the year 2005 started with the CNG over the diesel name as Ferrocarril central andino.
-The second advantage in the world first bike comes with a factory fitted with CNG powder launched in the Argentinian company zenella. And in India Bajaj RE CNG auto 4 stroke launched by the Bajaj auto.

Note: As compared to the conventional gasoline powered vehicles, CNG vehicles required a greater amount of space for fuel storage. CNG takes up more space for each gasoline gallon equivalent since it is a compressed gas as compared to the liquid gasoline. CNG is cheaper than other fuel like petrol and diesel, and many more reasons due to this CNG is the most useful for vehicles as compared to the other gases.
