Thermal Energy
In an internal combustion engine fuel is burned in a combustion chamber or cylinder inside the engine
An internal combustion engine converts chemical energy into Thermal Energy, and converts thermal energy into mechanical energy via the pistons, connecting rods, and crankshaft .
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, 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.
A motor that converts thermal energy to mechanical energy is called a heat engine. Heat engines operate by using a temperature difference to generate work, such as a steam engine or an internal combustion engine. The thermal energy is converted into mechanical energy through the expansion of a working fluid.
