masouds, you’re absolutely right. That’s the beauty of fuel – you add a small amount of energy (like a match or a spark) to break the first bonds. When those atoms reform into a lower energy state, the excess energy is released as heat and continues breaking other bonds. That’s why fires are self sustaining until the fuel (or the oxygen) runs out.

So overall you put in a small amount of energy to get things started and end up with a large amount of heat energy that you can use. In the sedans, it’s converted into mechanical energy (motion) and in an power turbine it’s converted into electrical energy.

Thank you for explaining how “combustion” and “high energy density” really work.

Just a technical correction; Breaking bonds between atoms *requires* energy. Forming new bonds between them releases energy. In the case of hydrocarbons, it just so happens that breaking C-C and C-H bonds, requires less energy than the energy released through formation of C-O and H-O, therefore the whole reaction (also known as burning) releases energy.
One other note: The simpler fuel has more C-H bonds than C-C; C-H bonds require less energy per mole to break than C-C, and thus generates more energy if they are burned completely.
