Agar nahi jaante toh jaan jaiye ki Internal Combustion Engines are those excellent gifts of technology to the automobile industry without which the roads would have been traffic-less!

What's An Internal Combustion Engine?

Combustion is the primary chemical process by which fuel and air are released as energy. It is commonly known as burning. In an Internal Combustion Engine (ICE), the gasoline is heated and burned within itself. Energy from the flame is partially converted to work by the engine.

George Brayton of the United States invented the first liquid-fueled internal combustion engine in 1872. The compressed, four-stroke cycle engine was patented by Nicolaus Otto in 1876, in collaboration with Gottlieb Daimler and Wilhelm Maybach.

The current production of internal combustion engines consists of gasoline spark-ignition engines and diesel compression ignition engines.

The majority of these internal combustion engines operate on a four-stroke cycle. This means that each round requires four piston strokes to complete. Intake, compression, combustion & power stroke, and exhaust are the four operations that make up the cycle.

Internal combustion engines (ICEs) are the most popular type of heat engine. They can be found in cars, boats, ships, planes and trains.

Difference Between External And Internal Combustion Engines

  1. Internal fuel combustion takes place within the working cylinder. On the other hand, external combustion of fuel takes place outside the working cylinder.
  2. ICEs take up less storage space. Alternatively, an external combustion engine takes up more areas.
  3. The capital cost of external combustion engines are higher than that of internal combustion engines.
  4. When you start the external combustion engines, it takes time to start. The internal combustion engines start easily and quickly.
  5. The efficiency of external combustion is about 20%-25%, whereas the internal combustion engines have 40%-45%.

Do you know that more than 100 million highway vehicles in India use ICEs? If not for them, excellent drivability and durability wouldn’t have been possible.

Also (for automobiles lovers out there), ICEs can use renewable or alternative fuels in addition to gasoline or diesel (e.g., natural gas, propane, biodiesel, or ethanol).
