The normal idle speed for Xiali N5 should be around 650 RPM. The N5 1.3 engine is designed for fuel economy, so the idle speed is relatively low. Hazards of high or low idle speed: A high idle speed increases fuel consumption, raises engine operating temperature, and accelerates machine wear. A low idle speed makes the car prone to stalling when starting, and frequent restarts are detrimental to both the engine and the starter. Additionally, excessively low idle speed can lead to stalling while driving, which is very dangerous. Over time, carbon deposits can accumulate in the engine cylinders, resulting in poor acceleration. Introduction to car idle speed: Idle speed refers to the engine running without any load, only overcoming the internal friction resistance of its components, without delivering power to the outside. The minimum speed required to maintain stable engine operation is called idle speed, which is one of the five basic operating conditions of an engine.

I've been driving a Xiali N5 for several years, and the normal idle speed is usually around 800 RPM. It tends to be slightly higher during cold starts but stabilizes once the engine warms up. Idle speed refers to the engine's RPM when the car is stationary. If it's too low, like below 700, the car may shake or even stall. If it's too high, above 900, it could lead to increased fuel consumption and affect the engine's lifespan. I often check the idle speed gauge—if I notice instability, it might be due to a dirty air filter or an issue with the idle control valve, which needs timely cleaning. Maintaining a proper idle speed helps the car run more fuel-efficiently and quietly. During routine maintenance every six months, it's a good idea to check the idle speed. Remember, seasonal changes can affect idle speed—higher RPMs in winter are normal.

My Xiali N5 idles steadily at 800 RPM, and I always check the tachometer upon each startup. If the idle speed is too high, it causes a humming noise and increased fuel consumption; if too low, the car shakes uncomfortably. The normal range is typically between 700 and 900 RPM. When I first bought the car, I was always curious about the idle speed. Now I realize it reflects the engine's health. When I turn on the AC or headlights, the increased load raises the idle speed to around 950 RPM, but it stabilizes again after releasing the throttle. I recommend that beginners learn to monitor the dashboard to avoid ignoring minor issues that could escalate into major faults due to abnormal idle speeds.

The idle speed of the Xiali N5 is normally around 800 RPM. Idle speed refers to the engine rotation when the car is stationary, which can be seen on the dashboard. If it's too low, the engine may stall; if it's too high, it consumes more fuel. A range of 700-900 RPM is considered appropriate. I once experienced idle speed fluctuations, and cleaning the throttle body solved the problem. Checking is simple: start the car, wait until it's warmed up, and note the RPM value.

I drive a Xiali N5 for commuting, keeping the idle speed at 800 RPM, and the car feels smooth and fuel-efficient. If the idle speed is too low, the car vibrates noticeably, making it uncomfortable for long sits. If it's too high, the engine noise increases and it wastes fuel. When waiting at red lights in the city, I usually check the tachometer—if it's between 700 and 900 RPM, I feel at ease. Factors like weather and turning on the lights can affect the idle speed, but it stabilizes after the engine warms up. I recommend regular maintenance to avoid unexpected issues caused by idle speed problems.
