Which Fuel Has Higher Energy: CNG or Petrol?
Discover the calorific value comparison between CNG and petrol to understand which fuel option is more advantageous.
Video transcript
Compressed Natural Gas (CNG) generally has a lower calorific value compared to petrol. CNG's calorific value is about 50,000-55,000 kJ/kg, while petrol's is approximately 44,000-46,000 kJ/kg. However, CNG is cleaner and often cheaper, making it an eco-friendly alternative to petrol despite its lower energy content.
