Compressed natural gas ( CNG) is a fuel gas made of petrol which is mainly composed of methane (CH 4 ), compressed to less than 1% of the volume it occupies at standard atmospheric pressure. Best Answer. The lowering of pollution is yet another advantage of both CNG and LPG. As it is using. CNG is more polluting fuel than petrol. After burning, it does not leave any solid residues behind, so it is a clean fuel and is less polluting than petrol or diesel. CNG is more polluting fuel than petrol. There are many reasons for it, some are as follows: 1. NEW DELHI: Compressed natural gas (CNG) was pitched as a silver bullet for Delhi's air pollution problem, but new research suggests exhaust emissions of CNG vehicles may also be harmful. Pollution- Petrol emits more harmful gases, on the other hand, CNG is more known for producing reduced harmful gases but emitting less harmful Greenhouse gasses. CNG is more polluting fuel than petrol.

(T/F) (e) Kerosene is not a fossil fuel. CNG is still an emerging alternate fuel type and is mostly found in metro cities like Delhi . where as CNG (Compressed Natural Gas) burns almost without smoke also CNG does not produce any poisonous gases. Less particulate emissions and NOx emissions than diesel but more CO and CO2 emissions. CNG is more polluting fuel than petrol and diesel. So, CNG is gas. CNG is more polluting fuel than petrol A True B Fa class 11 chemistry CBSE Was this answer helpful? And because CNG fuel systems are completely sealed, CNG vehicles produce no evaporative emissions. Fossil fuels are inexhaustible natural resources. So it is less harmful. Goes the Distance. Answer. They may not be as toxic as diesel fumes but, scientists at Council of Scientific and Industrial Research (CSIR) say, gases produced while burning CNG . It is stored and distributed in hard containers at a pressure of 20-25 MPa (2,900-3,600 psi), usually in cylindrical or spherical shapes. Fuel efficiency for compressed natural gas vehicles can be difficult for the consumer to calculate, as the metric for fuel efficiency in CNG and LNG vehicles isn't actually miles per gallon (MPGs), . (True or False) Class 8th Physics Answered 184 Views Solutions : Balendu Anand Answered on 4th Feb, 2021 It's a false statement because CNG emits significantly less pollution than petrol or gasoline. Diesel and petrol cars give more carbon emissions together with sulfur dioxide and nitrogen dioxide.
