Answers
Answer:
CNG
Explanation:
CNG emits significantly less pollution directly than gasoline or oil when combusted (e.g., unburned hydrocarbons (UHC), carbon monoxide (CO), nitrogen oxides (NOX), sulfur oxides (SOx) and PM (particulate matter)). For example, an engine running on petrol for 100 km produces 22 kilograms of CO 2, while covering the same distance on CNG emits only 16.3 kilograms of CO 2.
