Does idling for 12 hours damage the car?

[RhettAnn]

Idling for 12 hours does damage the car. Here are some extended details: 1. Definition of idling: Idling refers to the operation of the engine without any load, where it only needs to overcome the internal friction of its components and does not output any power. The minimum speed required to maintain stable engine operation is called the idle speed, which is one of the five basic operating conditions of an engine. A well-functioning engine typically has an idle speed between 550 to 800 RPM. 2. Hazards of prolonged idling: Prolonged idling can cause the engine temperature to drop too low, leading to incomplete fuel combustion, which can easily produce carbon deposits that clog the fuel injectors. Severe carbon buildup can cause the piston rings to seize or even break. Additionally, prolonged idling results in poor fuel atomization, and unburned atomized diesel can condense and wash down the cylinder walls, entering the lubricating oil and diluting it. This deterioration of the lubricating oil leads to insufficient lubrication of the engine's moving parts, accelerating engine wear.
