Difference between internal combustion engine and external combustion engine.

Question

Accepted Answer

Internal combustion engines burn fuel inside the engine, while external combustion engines burn fuel outside the engine.

Internal combustion engines burn fuel inside the engine, while external combustion engines burn fuel outside the engine.
In internal combustion engines, the combustion of fuel and air mixture occurs within the cylinders, producing high-pressure gases that drive the piston.
Examples of internal combustion engines include gasoline engines, diesel engines, and natural gas engines.
External combustion engines, on the other hand, burn fuel outside the engine to generate heat, which is then used to produce mechanical energy.
Steam engines and Stirling engines are examples of external combustion engines.
In external combustion engines, the heat generated from burning fuel is transferred to a working fluid, such as water or air, which then expands and drives the engine's components.
Internal combustion engines are more commonly used in automobiles, motorcycles, and small machinery, while external combustion engines are often found in power plants and large industrial applications.
