Best Answer

In an Internal Combustion Engine, the fuel is burned in the cylinder or vessel. Eg. Diesel or Petrol engine used in Cars.

  • Internal engine has its energy ignited in the cylinder, like 99.9% of engines today.
In an External Combustion Engine, the internal working fuel is not burned. Here the fluid is being heated from an external source. The fuel is heated and expanded through the internal mechanism of the engine resulting in work. Eg. Steam Turbine, Steam engine Trains.
  • An external combustion example is a steam engine where the heating process is done in an boiler out side the engine.

Internal combustion engines burn fuel inside the engine to generate power, while external combustion engines burn fuel outside the engine and use the resulting heat to create power, such as in steam engines. Internal combustion engines are more common in vehicles due to their compact size and efficiency, while external combustion engines are used in specific applications like power plants and some marine propulsion systems.

What is the difference between internal combustion engine and external combustion engine?

An internal combustion engine burns fuel internally to produce power, like in cars and motorcycles. An external combustion engine burns fuel externally to produce power, often using a separate heat source to generate steam, like in steam engines or some power plants.


What is the difference between combustion and breathing?

Combustion is a chemical reaction where a substance reacts with oxygen to produce heat and light, while breathing is the physiological process where organisms take in oxygen and release carbon dioxide. Combustion is an external chemical reaction, while breathing is an internal biological process necessary for survival.


What is the difference between a external parasite and a internal parasite?

An external parasite lives on the outside of its host, such as on the skin or feathers, like ticks or lice. An internal parasite, on the other hand, lives inside the host, typically in organs or the bloodstream, like worms or protozoa.


Why heating a can and putting it in water?

Heating a can and then submerging it in water can create a pressure difference between the inside and outside of the can. When the can is rapidly cooled in water, the pressure difference causes the can to collapse due to the external pressure being greater than the internal pressure.
