External-combustion engine meaning

External-combustion engine definitions

External-combustion engines, also known as external heat engines, are a type of engine where the combustion of fuel takes place outside of the engine. These engines work by burning fuel to create heat, which is then used to generate power. Unlike internal combustion engines, external-combustion engines do not mix fuel and air inside the combustion chamber.

One of the most common examples of an external-combustion engine is the steam engine. In a steam engine, fuel is burned in a boiler to produce steam, which is then used to drive a piston or turbine. These engines played a vital role in the Industrial Revolution and were used to power trains, ships, and factories.

Types of External-Combustion Engines

There are several different types of external-combustion engines, each with its unique design and method of operation. Some common types include steam engines, Stirling engines, and external combustion turbines. Each type has its advantages and disadvantages, making them suitable for different applications.

Advantages of External-Combustion Engines

One of the significant advantages of external-combustion engines is their ability to use a variety of fuels. These engines can run on coal, wood, oil, or even solar power, making them versatile and adaptable to different situations. External-combustion engines also tend to be more fuel-efficient than internal combustion engines, making them an attractive option for certain applications.

Disadvantages of External-Combustion Engines

Despite their advantages, external-combustion engines also have some disadvantages. They are typically larger and heavier than internal combustion engines, making them less suitable for use in vehicles. External-combustion engines also tend to have slower response times and lower power-to-weight ratios, which can limit their performance in certain situations.

In conclusion, external-combustion engines have played a crucial role in the history of engineering and continue to be used in various applications today. While they may not be as common as internal combustion engines, they offer unique advantages that make them well-suited for specific tasks. As technology continues to evolve, external-combustion engines may see a resurgence in popularity due to their efficiency and versatility.
