Question

why is CNG preferred as a fuel to petrol and diesel?
​

Answer 1

Answer:

Very low NOx and PM emissions.

Compared to diesel and even to petrol, natural gas creates far less nitrogen oxides (NOx) and particulate matter (PM) when combusted. The combustion process is also quieter. CNG is therefore a better 'urban' fuel than diesel. Lower CO2 emissions, both tailpipe and well-to-wheel.

Answer 2

Answer:

CNG is preferred as a better fuel than petrol and diesel because it is a natural gas and does not release harmful gases while burning and reduces pollution.
