Fuels Engineering Chemistry Quiz

Introduction to Fuels

• A fuel is a substance that contains carbon and hydrogen and undergoes combustion in the presence of oxygen to produce a large amount of energy.

Classification of Fuels

• Fuels can be classified into two categories based on their occurrence:
  • Natural or Primary Fuels: These fuels are naturally present.
  • Artificial or Secondary Fuels: These fuels are synthesized from primary fuels.
