(b) CNG is more polluting fuel than petrol. The PTSC now reports that 71 of its buses use the fuel - just 21 per cent of its fleet. And because CNG fuel systems are completely sealed, CNG vehicles produce no evaporative emissions. 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. However, CNG is much less polluting and hence, much more environmentally acceptable that conventionally used petrol/diesel. Lower CO2 emissions: Cars that run on CNG emit 30 per cent less carbon dioxide than variants burning diesel or petrol. It is actually the cleanest of all fossil fuels. In use, on average, this . CNG cars and vans, unlike their diesel and petrol counterparts, are not subject to a particle number emission limit. Diesel and petrol cars give more carbon emissions together with sulfur dioxide and nitrogen dioxide. (T/F) (d) Coal tar is a mixture of various substances. Coal tar (e) Produce more energy: 6. Disadvantages. Saves 70% of fuel cost CNG is cost effective as . (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. In a 2011 study of RNG production methods, Argonne National Laboratory concluded that all RNG methods show significantly less GHG emissions and fossil fuel consumption than conventional fossil natural gas and gasoline. Therefore, we can say that the statement given in the question is False. Answer. CNG is more polluting than petrol. where as CNG (Compressed Natural Gas) burns almost without smoke also CNG does not produce any poisonous gases. . Cng is More Polluting Fuel than Petrol. Since the calorific value is more and the products formed as a result of combustion are less polluting agents When compared with petrol and diesehit is pre ferred. This feature makes them a particularly good choice in densely populated areas or for night-time use. (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 . Disadvantages.
