What Causes BMW's Unstable Idle Speed Fluctuation?

BMW's unstable idle speed fluctuation can be attributed to the following reasons: 1. Intake pipe leakage. The intake system contains numerous intake manifolds or various valves, and any leakage can allow unwanted air to enter, causing the air-fuel mixture in the intake manifold to become either too rich or too lean, ultimately leading to unstable or fluctuating idle speed. 2. Fuel system blockage or malfunction. Blockages in the fuel tank vent hole, fuel tank switch, fuel filter, or the fuel line between the tank and the carburetor can prevent the engine from receiving the required amount of fuel during idle, resulting in a lean mixture and unstable idle speed. 3. Idle control valve failure. The idle operation of electronically fuel-injected engines is mostly controlled by the idle control valve. A malfunction can cause uneven air distribution, leading to fluctuating power output at idle. 4. Carbon buildup. Excessive carbon deposits inside the engine can reduce ignition energy and intake efficiency, ultimately causing unstable power output, idle speed fluctuations, and poor acceleration. 5. Cold start. During a cold start, the engine injects more fuel, resulting in a higher idle speed, especially after prolonged inactivity or in cold environments. The idle speed will return to normal once the engine warms up.

What are the working processes of ABS?

The working process of ABS includes stages such as conventional braking, brake pressure maintenance, brake pressure reduction, and brake pressure increase. The anti-lock braking system performs pulsed braking at a frequency of 6 to 10 times per second, alternating between braking and releasing, using electronic intelligent control instead of manual control to prevent wheel lock-up. This ensures the wheels always obtain maximum braking force while maintaining steering flexibility. Additional information: 1. ABS working principle: It consists of control devices and ABS warning lights. In different ABS systems, the structural form and working principle of the brake pressure regulation device may vary, and the internal structure and control logic of the electronic control device may also differ. 2. The function of the ABS system: The anti-lock braking system can improve the safety factor of a vehicle during emergency braking. In other words, cars without ABS are more prone to wheel lock-up when emergency braking is applied in critical situations, meaning the steering wheel cannot be turned, thereby increasing the risk factor and potentially leading to severe consequences.
