An engine or motor is a machine designed to convert energy into useful mechanical motion. Heat engines, including internal combustion engines and external combustion engines (such as steam engines) burn a fuel to create heat, which then creates motion. Electric motors convert electrical energy into mechanical motion, pneumatic motors use compressed air and others such as clockwork motors in wind-up toys use elastic energy. In biological systems, molecular motors, like myosins in muscles, use chemical energy to create motion.

In an industrial or manufacturing context, "engine" typically refers to a machine or device that converts energy into mechanical work. Engines can be powered by a variety of energy sources, including electricity, fossil fuels, and renewable energy.

For example, in the transportation industry, engines are used to power vehicles such as cars, trucks, and airplanes. In the power generation industry, engines are used to convert fossil fuels such as coal, oil, and natural gas into electricity. In the manufacturing industry, engines are used to power machinery and equipment.

For example, in the construction industry, engines are used to power heavy equipment such as bulldozers, excavators, and cranes. In the marine industry, engines are used to power ships, boats, and other watercraft.

In the field of aerospace, engines are used to power aircraft, rockets and satellites.

It's worth noting that engines are critical components in many industrial and manufacturing processes, and they play a crucial role in powering transportation, power generation, and a wide range of other applications. Advances in technology have led to the development of more efficient and environmentally friendly engines, such as electric and hybrid engines, which are being increasingly used in various industries.
