What needs to be replaced when water enters the engine?

[VonJohn]

When water enters the engine, important components such as pistons, connecting rods, and valves need to be replaced. Engine function: It is the machine that provides power to the car. A car engine is essentially an energy conversion mechanism that transforms the thermal energy from gasoline, diesel, or natural gas into mechanical energy by burning the gas in a sealed cylinder to expand it and push the pistons to perform work. Engine introduction: An engine (Engine) is a machine capable of converting 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, internal combustion engines typically convert chemical energy into mechanical energy.
