What Happens If a Car Is Left Idling for a Long Time?
1 Answers
Leaving a car idling for a long time will: 1. Keep the engine running at low RPM, making it easier for carbon deposits to form on the pistons and valves, which can lead to unstable idling and other adverse effects on engine performance; 2. Increase component wear—during idling, the lower oil pressure in the engine worsens lubrication conditions for moving parts, and incomplete fuel combustion can lead to carbon buildup; 3. Increase fuel consumption—when the engine runs at very low RPM, the intake swirl weakens, resulting in poor fuel atomization and incomplete combustion; 4. Increase air leakage from valves and piston rings when the engine runs at very low RPM.
