What is the idle speed of a car?
2 Answers
Under normal circumstances, the idle speed of a car ranges between 600-850 RPM. However, reaching 600 RPM is quite difficult, and most car models have an engine idle speed around 700~800 RPM. Here is some information about car idle speed: 1. Introduction: Idle speed is an operational condition of a car, referring to the engine running in neutral gear. The engine speed during idle is called the idle speed. The idle speed can be adjusted by modifying the throttle opening size, among other methods. Idle speed means the engine is "producing power without doing work." 2. Repair and Adjustment: When the engine is running, if the accelerator pedal is completely released, the engine enters idle state. When adjusting the idle speed, the RPM should not fluctuate abruptly, as this can cause premature wear to the engine. It is best to have the idle speed adjusted at an automotive repair facility.
I've driven quite a few cars before, and the idle speed usually ranges between 600 to 1000 RPM, depending on the car model and environment. For example, my old car idles at around 700 RPM, staying very steady at red lights. However, when starting a cold engine, it might go up to 1000 RPM and then drop back to normal once the engine warms up. In colder weather or when the AC is on, the RPM might briefly jump to around 800 RPM, which is generally not a big issue. If the idle becomes unstable or too low, say 500 RPM, the car might shake noticeably or even stall. In such cases, it's necessary to check the throttle body or sensors; otherwise, long drives could become quite stressful. Many newer cars adjust automatically, but regular maintenance can prevent carbon buildup and related troubles.
