Does Idling a Car in Place Cause Damage to the Vehicle?

[LincolnDella]

Idling a car in place can cause damage to the vehicle. When the engine operates solely at idle speed, incomplete combustion of gasoline occurs, leading to the production of toxic substances such as carbon monoxide. If the car doors and windows remain tightly closed for an extended period in such conditions, exhaust gases can enter the enclosed cabin. During idling, fuel cannot burn completely, resulting in the generation of more harmful gases. Additionally, some gasoline may form deposits under high temperature and oxygen exposure, adhering to internal engine components and eventually turning into carbon buildup under prolonged heat. Furthermore, idling reduces oil pressure in the engine, worsening lubrication conditions, and may cause stalling during low-speed deceleration or when stopping.
