Internal combustion engine

Definition

An internal combustion engine is a type of heat engine that converts fuel into mechanical energy through the process of combustion occurring within the engine itself. This invention revolutionized transportation and manufacturing, leading to significant economic growth during the industrial era as it enabled faster and more efficient movement of goods and people, supporting the expansion of industries and urban centers.

5 Must Know Facts For Your Next Test

1. The internal combustion engine was first developed in the late 19th century and became widely used in automobiles, replacing horse-drawn carriages.
2. This engine operates by igniting a mixture of fuel and air within cylinders, generating power through the resulting explosion that pushes pistons.
3. The introduction of internal combustion engines led to the expansion of road networks and increased demand for oil as a fuel source, significantly impacting global economies.
4. Internal combustion engines are categorized into two types: spark-ignition engines (like gasoline engines) and compression-ignition engines (like diesel engines).
5. The efficiency and power output of internal combustion engines have improved over time due to advancements in engineering, making them a critical component of modern transportation.
