List five whats engines can be classified?

Answer 1

Engines can be classified into five main categories: internal combustion engines, which burn fuel to create power; external combustion engines, where fuel is burned outside the engine, such as steam engines; electric engines, which convert electrical energy into mechanical energy; hybrid engines, combining internal combustion and electric power sources; and rocket engines, designed for propulsion in space by expelling mass at high velocity. Each type serves different applications and operates on distinct principles.
