A car engine is technically a heat engine that has no energy of its own but it converts the chemical energy in the fuels into heat and then into kinetic energy by turning a rotating shaft.

The carbon reacts with oxygen to produce carbon dioxide and heat, while the hydrogen reacts with oxygen to produce water and heat.
