Does Prolonged Idling Affect the Engine?

[Pamela]

Prolonged idling does affect the engine. Here is a related introduction about car idling: 1. The function of car idling: Idling is an operating condition of a car, referring to the engine running in neutral gear. The engine speed during idling is called the idle speed. The idle speed can be adjusted by modifying the throttle opening size, among other methods. Idling means the engine is "exerting force without doing work." When the engine is running, if the accelerator pedal is completely released, the engine enters the idling state. 2. Causes of unstable idling: Direct causes refer to mechanical parts being dirty, worn, or incorrectly installed, leading to changes in cylinder power and resulting in an imbalance of power among cylinders, causing unstable engine idling. Indirect causes refer to abnormalities in the engine's electronic control system, leading to poor combustion of the air-fuel mixture, making it difficult to balance the power among cylinders and causing unstable engine idling.
