Is High Idle Speed During Cold Start Normal?

[OReed]

High idle speed during cold start is normal. The purpose of this is to allow the engine to warm up quickly. Automobile engines have an optimal operating temperature, and lower engine temperature is not necessarily better. If the engine temperature is too low, it can lead to increased fuel consumption, reduced power, and higher exhaust emissions. An engine is a machine that converts other forms of energy into mechanical energy. It was invented in England and can refer to either the power generation unit or the entire machine including the power unit. Types of engines include internal combustion engines (such as gasoline engines), external combustion engines (such as Stirling engines and steam engines), and electric motors.
