What is an engine?
1 Answers
An engine is a machine that converts other forms of energy into mechanical energy, including internal combustion engines (such as gasoline engines), external combustion engines (such as Stirling engines and steam engines), and electric motors. For example, internal combustion engines typically convert chemical energy into mechanical energy. Here is some related information: 1. Applications of engines: Engines can be used as power generation devices or refer to entire machines that include power units (e.g., gasoline engines, aircraft engines). 2. The birth of engines: The engine was first developed in the UK, so the concept of an engine originates from English. Its original meaning refers to "a mechanical device that generates power." 3. Classification of engines: Automotive engines can be divided into two main categories: gasoline engines and diesel engines. They share the same basic structure, consisting of two major mechanisms and five systems: the crankshaft-connecting rod mechanism, the valve train, the fuel supply system, the lubrication system, the cooling system, the ignition system, and the starting system. 4. How an engine works: An engine does not rotate on its own without reason; it requires an external force to provide the initial power, which is supplied by the engine's starting system. During normal operation, the engine's working cycle includes four piston strokes: intake, compression, power, and exhaust.
