Heat energy is released in a heat engine when fuel is burned. The heat energy is then changed into mechanical energy.
The type of conversion that is taking place when natural gas is burned to heat water is referred to as chemical conversion. In this conversion thermal energy is produced.
When fuel is used by an engine, the chemical energy stored in the fuel is converted into thermal energy through combustion. The thermal energy is then used to produce mechanical energy that powers the engine, ultimately moving the vehicle or performing work.
The importance of engine is gigantic! As we all know engine is the heart of power plant. Inside the engine they are taking place 3 conversions: At first, the fuel injected into the combustion chamber and combustion takes place. The chemical energy of fuel is converted into thermal energy! Thermal energy is received and converted by the piston to Mechanical energy which is led to installation's shaft! All these processes are taking place inside the engine, and must complete with accuracy! So, it is absolutely understood that engine is of vital importance for the whole installation!

In the engine of a typical train, the energy transformation that takes place involves converting the chemical energy stored in fuel (such as diesel) into mechanical energy through combustion. This mechanical energy is then used to move the train by powering the wheels.
Answer : Conversion Energy.
When a kerosene stove is lit, chemical energy stored in the kerosene molecules is converted into thermal energy (heat) and light energy through the process of combustion. The burning of the kerosene releases energy in the form of heat and light, which is used for cooking or heating purposes.
In steam and combustion engines, thermal energy is changed to mechanical energy. Either heated gas or heated fluid is created that exerts force to turn the engine. In combustion engines, chemical energy becomes thermal energy which becomes mechanical energy. In electrical engines (motors), electrical energy is changed to mechanical energy by the manipulation of magnetic fields.
Combustion reactions are useful to humans because they provide heat energy for cooking, heating, and generating electricity. They also power vehicles and machinery by converting chemical energy into kinetic energy.
External Combustion engine is an engine in which combustion of fuel takes place outside the cylinder. e.g.Coal fired steam engines in trains
Chemical energy is converted to thermal energy.The conversion that is taking place is chemical energy into thermal energy. The type of conversion is taking place when natural gas is used to heat water is chemical energy that is turned into thermal energy.
An aeroplane's engine sucks air. Combustion takes place due to jet fuel. The force of the combustion propels the aircraft.
