The term "Real Engine" refers to an internal combustion engine that is designed and built for use in automobiles, trucks or other vehicles. It generates power by burning fuel (usually gasoline) in a cylinder to turn a crankshaft which then powers the wheels of the vehicle through a transmission system. Real engines are typically made up of several components including pistons, connecting rods, cam shafts and valves that work together to convert fuel into mechanical energy. These engines can be designed in various ways such as V-type, inline or flat engines depending on their intended use and the vehicle's design requirements.
