Heat engine are physical working machines, therefore they are fact
Yes. Heat engines come in various forms. For example, internal combustion using gasoline or diesel, external combustion (not much used), steam engines reciprocating or turbine, gas turbines, rocket engines.
Atmospheric engines, or 'Stirling' engines, can make use of waste or naturally occuring heat differences, to work.
No. electric motors aren't heat engines.
internal and external combustion engine
Heat engine is the gate way of transform thermal energy into another form of easy access energy. It allow us the refrigeration cycle and come the air condition, Popsicle and the refrigerator. It would take at least 3 times the electricity to heat up over winter compare to the transformation of electricity to heat by a heat engines. Our vehicle is operated base on heat engines principle and separated the medieval era with comfortness of modern society.

The caloric fluid theory was a scientific hypothesis that suggested heat was a substance called "caloric" that flowed from hotter bodies to cooler bodies, explaining thermal phenomena. However, this theory was eventually replaced by the kinetic theory of heat, which proposed that heat is the motion of particles at the microscopic level.
who knows fact not theory

It is a fact that fire is hot. Fire produces heat through chemical reactions that release energy in the form of heat and light. This heat can cause burns and ignite other materials.
According to the theory of heat engines (read about "Carnot cycle" for more details), heat can not be converted 100% to other forms of energy. The remaining energy gets transferred from the "reservoir" of higher temperature, to the "reservoir" of lower temperature. The latter would be the environment. For example, if the heat engine works at 600 Kelvin, and the environment has a temperature of 300 Kelvin, in theory half the heat of the higher-temperature reservoir can be used. However, real engines have a lower efficiency than the theoretical maximum according to Carnot.

It is a fact im studying it and I know know this is a fact.
A hypothesis is a prediction on what you think will happen. For experiments on insects being attracted to light or heat, a hypothesis could be that insects are attracted to light over heat.
The greenhouse hypothesis is the theory that increased levels of greenhouse gases, such as carbon dioxide and methane, in Earth's atmosphere are causing a warming effect on the planet. These gases trap heat from the sun, leading to global warming and climate change.
engines get discolored because of the heat . the heat comes from combustion from gass and air
