Does prolonged idling affect a sedan?

[JeffreyAnn]

Prolonged idling can indeed have negative effects on a sedan. Here are the specific impacts of extended idling: 1. When the engine idles for long periods, the throttle opening remains small, requiring the fuel injectors to spray high-concentration fuel to maintain operation. Consequently, idling is more prone to causing carbon buildup than high-speed driving. Severe carbon deposits from prolonged idling directly impair the vehicle's power performance and comfort. 2. Idling significantly increases fuel consumption. Three minutes of idling consumes fuel equivalent to driving one kilometer. 3. During idling, lower cylinder temperatures and pressures prolong fuel ignition time, while reduced cylinder sealing makes the engine more susceptible to knocking sounds, shortening its service life. 4. Extended idling creates excessively rich air-fuel mixtures, resulting in low oxygen content in exhaust gases. Unburned mixture combusting at the catalytic converter can easily damage this component.
