Combustion Engines (02:25)


An engine is an apparatus that transforms energy into mechanical labor. Combustion engines use the heat from burning or exploding fuel. They are divided into two groups, internal and external.

External Combustion Engines (02:46)

These engines burn fuel outside of the engine. Steam engines boil water to produce steam, which moves the piston. Their use in locomotives and steamboats greatly revolutionized travel in the 19th century.

Internal Combustion Engines (04:06)

The majority of land vehicles use internal combustion engines. This engine appeared during the second half of the 19th century; Nikolaus Otto invented the first four-stroke engine. Other types include the two-stroke, diesel, and gas turbine engines.

We rely on machines in everyday life, and those machines rely on energy. Learn about the different sources of energy that power machines: heat, fuels, electricity, and nuclear energy. We’ll also cover external and internal combustion engines, steam engines, thermal power stations, Nicholas Otto and the four-stroke piston engine, and inventors Rudolph Diesel and Thomas Newcomen.
