Thermal Energy
An internal combustion engine converts chemical energy into Thermal Energy, and converts thermal energy into mechanical energy via the pistons, connecting rods, and crankshaft .
In an internal combustion engine fuel is burned in a combustion chamber or cylinder inside the engine
The source of thermal energy in an internal combustion engine is from the combustion of fuel (such as gasoline or diesel) inside the engine cylinders. The controlled explosion of the fuel-air mixture generates heat energy that is converted into mechanical energy to power the vehicle.
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.
In an internal combustion engine, chemical energy from the fuel is converted into thermal energy through combustion. This thermal energy increases the temperature and pressure of gases within the engine, which then expands to perform mechanical work by moving the pistons. Finally, the mechanical energy is transformed into kinetic energy that powers the vehicle. Overall, the process involves the conversion of chemical energy to thermal energy, then to mechanical energy, and finally to kinetic energy.
In an internal combustion engine, the provided energy is chemical energy. By means of combustion it is transformed into heat energy. This heat energy is transformed in to motion/kinetic energy in an internal combustion engine.
This is a heat engine, they come in various types such as internal combustion, external combustion, steam turbines, gas turbines, etc.
You can transform thermal energy to electrical energy in a power plant, chemical energy to mechanical energy in an internal combustion engine, or nuclear energy into thermal energy in a nuclear reactor. These are just three examples.
The output of every internal combustion engine is usually thought of as kinetic energy, but as a byproduct, thermal energy also is expelled as a result of the combustion of hydrocarbons. The primary fuel source. Additionally, much kinetic energy is also lost as a result of friction thereby also creating a thermal energy. So although the sources of both seem different, there would be no friction without first there being kinetic energy as a result of the combustion of hydrocarbon and oxygen.
