Will the car be the same as before after an engine replacement?

[Juniper]

Replacing the engine has a certain impact on the car. Installing a new engine may slightly reduce fuel consumption and improve power, but after the vehicle has been used for some time and carbon deposits build up, fuel consumption and power will correspondingly increase and decrease. Below is relevant information about car engines: 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 (such as Stirling engines, steam engines, etc.), jet engines, electric motors, etc. For example, an internal combustion engine typically converts chemical energy into mechanical energy. Expansion: An engine can refer to both the power generation device 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."
