What are engines?

An engine is a motor that has been designed for a machine to convert one form of energy into mechanical energy. In 1872, George Bratton invented the first commercial liquid-fueled IC engine. In 1876, Otto, Daimler and Maybach patented the compressed charge four-stroke cycle engine, and in 1872, Karl Benz created a reliable two-stroke gas engine.

What are common types of engines?

There are two common types of engines:

• Spark ignition gasoline engine
• Compression ignition diesel engine

These can be subdivided into:

• Electrical
• Physical

What is the purpose of an engine?

It is the primary source of power in a vehicle. The engine uses fuel and burns it to produce mechanical energy. The heat is produced through combustion, which is used to create pressure and drive an automatic device.

Where are engines used?

Engines are used in several applications such as:

• Vehicles
• Boats
• Ships
• Aeroplanes
• Trains

In application, the engine's function is initiated when fuel is ignited, and the rest of the functional work is done within the engine by the gases expanding into the pistons.
