Questions and Answers

Which type of fuel is mentioned to be ideal for internal combustion engines due to their homogeneous mixing with air?

  • Charcoal fuels
  • Solid fuels
  • Liquid fuels
  • Gaseous fuels (correct)

    • Why are solid fuels considered unsuitable for internal combustion engines in their solid form?
