What are the effects of prolonged idling on the engine?
2 Answers
Prolonged idling has the following effects on the engine: Combustion inside the engine becomes incomplete, leading to increased carbon deposits in the engine. If carbon deposits accumulate in the intake tract, they can affect the engine's air intake, resulting in an incorrect air-fuel ratio. If carbon deposits form in the combustion chamber, they can increase the compression ratio of the combustion chamber, thereby raising the likelihood of engine knocking. An engine (Engine) is a machine capable of converting other forms of energy into mechanical energy, including internal combustion engines (reciprocating piston engines), external combustion engines (such as Stirling engines, steam engines, etc.), jet engines, electric motors, and more.
I think prolonged idling has a significant impact on the engine. Based on my decades of driving experience, when idling, the engine keeps running at low speed, which can easily cause the oil temperature to become too high or too low. Over time, carbon deposits can build up in the fuel system, especially in winter or hot weather. This can clog the fuel injectors, make the engine sound louder, and increase fuel consumption. I still remember a friend whose car idled for too long, and later it cost a lot to repair because the valves and spark plugs were corroded. Normally, I turn off the engine if I park for more than a minute. This helps protect engine components, reduce wear, save fuel, and extend the engine's lifespan. It's a good habit for any car owner.
