Is It Harmful to Keep the Car Idling Without Moving?

[StHope]

Keeping the car idling without moving can cause damage to the vehicle. When the car remains stationary while the engine is running, it enters an idle operating condition. Idle operation refers to the state where the engine runs without any load, meaning the clutch is engaged, and the transmission is in neutral (for automatic transmission vehicles, it should be in 'Park' or 'P' mode). Causes the engine temperature to be too low: Due to prolonged idling, the engine temperature becomes too low, leading to incomplete fuel combustion, which can easily cause carbon buildup, clog the fuel injectors, and result in severe carbon deposits. Poor fuel atomization, causing lubricant deterioration: Unburned and unatomized oil can wash the cylinder walls and enter the lubricating oil, diluting and deteriorating the lubricant. This can lead to insufficient lubrication for the engine's moving parts, accelerating engine wear. Releases toxic gases: Poor engine combustion worsens exhaust emissions, releasing toxic gases.
