In a car engine the fuel, which consists of carbon and hydrogen, is combined with oxygen from the air to produce carbon dioxide and water. Both these processes produce heat inside the cylinder, and they cause the gas in the cylinder to have an extremely high pressure.
Each pound of fuel used gives rise to about 3 pounds of carbon dioxide. The gain in mass comes from the oxygen taken from the atmosphere.
The gas pushes the piston down inside the cylinder, and it pushes the big-end via the con-rod to rotate the crankshaft. The energy is now mechanical energy and it goes along the transmission to the drive-wheels to propel the car forward.
Only about 20% of the energy in the fuel goes to drive the car. The rest is dissipated from the radiator, or else it goes out in the hot exhaust gases.
A combustion engine transfers thermal energy to move one or more pistons that provide power. An example of a combustion engine is an engine in a car.

heat It transfers engine heat from the coolant to the air inside the car.
The chemical energy is transformed in kinetic energy.
Chemical energy transforms to kinetic energy which makes the car move.
Heat
kinetic energy is created
The radiator is made of copper because copper transfers heat very well.
Chemical Energy into Mechanical Energy
It starts the engine
