- Compressed natural gas, or CNG, is natural gas under pressure which remains clear, odourless, and non-corrosive – and can be used as a cheaper, greener, and more efficient alternative to the traditional petrol and diesel fuels for vehicles.
- CNG is comprised mostly of methane gas which, like gasoline, produces engine power when mixed with air and fed into your engine’s combustion chamber.
- CNG engines run more quietly due to the higher-octane rating of CNG over gasoline and they produce less exhaust emissions. Harmful emissions such as carbon monoxide (CO), carbon dioxide (CO2) and nitrous oxide (N2O) can be reduced by as much as 95% when compared to gasoline powered vehicles.

Consider the following statements regarding Compressed natural gas (CN...
Statement 1: CNG is comprised mostly of methane gas.
Yes, this statement is correct. Compressed Natural Gas (CNG) is primarily composed of methane gas (CH4), which is the main component of natural gas. Methane is a hydrocarbon gas and is the cleanest burning fossil fuel. It is widely used as a fuel for vehicles and industrial applications due to its lower carbon content and less harmful emissions compared to other fossil fuels.
Statement 2: CNG engines run more quietly due to the higher octane rating of CNG over gasoline.
Yes, this statement is correct. CNG has a higher octane rating compared to gasoline. Octane rating is a measure of a fuel's ability to resist knocking or pinging during combustion. CNG's higher octane rating allows engines to run more smoothly and quietly. This is because CNG has a higher resistance to pre-ignition, which reduces engine knocking and noise.
Statement 3: CNG vehicles reduce harmful emissions such as carbon monoxide (CO), carbon dioxide (CO2), and nitrous oxide (N2O) by more than 90% when compared to gasoline-powered vehicles.
Yes, this statement is correct. CNG is considered a cleaner fuel compared to gasoline. When CNG is burned, it produces lower levels of harmful emissions such as carbon monoxide (CO), carbon dioxide (CO2), and nitrous oxide (N2O) compared to gasoline-powered vehicles. Studies have shown that CNG vehicles can reduce these harmful emissions by more than 90% when compared to their gasoline counterparts. This reduction in emissions helps to improve air quality and reduce the environmental impact of transportation.
Therefore, all three statements are correct. CNG's composition mainly consists of methane gas, its higher octane rating contributes to quieter engine operation, and CNG vehicles significantly reduce harmful emissions when compared to gasoline-powered vehicles.
