What Causes White Spots on Aluminum Engine Surfaces?
1 Answers
White spots on aluminum engine surfaces may be caused by water washing or air pollution. Below is an introduction to engines: 1. Introduction: An engine (Engine) is a machine that can convert other forms of energy into mechanical energy, including internal combustion engines (reciprocating piston engines), external combustion engines (Stirling engines, steam engines, etc.), jet engines, electric motors, etc. For example, an internal combustion engine typically converts chemical energy into mechanical energy. Engines can refer to both power-generating devices and the entire machine that includes the power unit (e.g., gasoline engines, aircraft engines). The engine was first developed in the UK, so the concept of an engine originates from English, with its original meaning referring to "a mechanical device that generates power." 2. Classification: External combustion engines: These engines burn fuel outside the engine; Internal combustion engines: Fuel burns inside the engine; Gas turbines: The working characteristic of this type of engine is that combustion produces high-pressure gas, which is used to rotate the turbine blades and output power; Jet engines: These engines directly generate thrust by expelling high-speed gas from a nozzle.
