Question

What are the two types of heat Engines?

Answer 1

In thermodynamics and engineering, a heat engine is a system that converts heat to mechanical energy, which can then be used to do mechanical work.

The two types of heat Engine are:

1. Internal combustion engine :
   1.1 In these heat engines, the fuel burns inside the cylinder (inside the engine).
   1.2 A car engine is an example of an internal combustion engine.
2. External combustion engine :
   2.1 In these heat engines, the fuel burns outside and away from the main engine where force and motion are produced.
   2.2 A steam engine is an example of an external combustion engine.
