What are the main reasons for unstable idle speed in electronic fuel injection engines?

Fuel system failures mainly include gasoline quality, fuel pump, fuel filter, fuel pressure regulator and its pipelines, as well as sludge and carbon deposits adhering to the throttle and fuel injectors. Electrical circuit failures primarily involve electronic control components, relays, fuses, and wiring issues. Reasons for unstable idle speed: 1. Intake system: The first reason is the intake system, including leaks in the intake pipe and various valves. Air entering from the intake pipe, gasoline vapor from the charcoal canister valve, and exhaust gases entering the intake pipe can cause the mixture to be too rich or too lean, leading to abnormal engine combustion. Excessive carbon buildup in the throttle and intake passages. ③ Inaccurate idle intake air volume. 2. Fuel system: Fuel injector malfunction. If the fuel injector has a drip or blockage, it cannot inject fuel according to the ECU's instructions, resulting in a mixture that is too rich or too lean, causing poor operation in individual cylinders and leading to unstable engine idle speed. Fuel pressure issues. If the fuel pressure is too low, the fuel sprayed from the injector will have poor atomization or form a line, and in severe cases, only droplets will be sprayed, reducing the fuel injection amount and making the mixture too lean; if the fuel pressure is too high, the actual fuel injection amount increases, making the mixture too rich. Inaccurate fuel injection amount. Faults in various sensors or wiring can cause the control unit to issue incorrect commands, resulting in incorrect fuel injection amounts and causing the mixture to be too rich or too lean, which is an indirect cause of unstable idle speed. 3. Ignition system: Most modern cars integrate the ignition module with the ignition coil or use dual ignition coils or direct ignition. First, the ignition module: if it malfunctions, it can cause weak sparks or no spark at all. For testing, you can only measure the secondary voltage in some models; the primary voltage is not visible, but you can test the ignition trigger signal. Issues with the ignition coil and ignition module may be due to missing ignition signals from the computer or problems with the ignition module's power supply lines. In actual repairs, this situation occurs frequently. New cars have a higher chance of experiencing this issue. When repairing new cars, some mechanics still spend a lot of time searching for various problems. For new cars, it's essential to ensure their power supply, both positive and negative terminals, operates reliably.

Why does the half shaft of Geely Vision keep falling out?

Geely Vision half shaft falling out may be due to deformation of the front suspension bracket. The following is detailed information about Geely Vision: 1. Model information: Geely Vision refers to Geely's first mid-level business family sedan. The Geely Vision was developed over more than 20 months, with five major performance indicators as design orientations: power, safety, space, handling, and comfort, marking the beginning of a new era for Geely Automobile. 2. Function: The automobile half shaft is used to transmit vertical forces, longitudinal forces, lateral forces, and reaction forces between the road surface and the vehicle frame or body. The automobile half shaft is located at the end of the transmission system, capable of changing the speed and torque from the transmission and transmitting them to the driving wheels.

What are the reactions of a car when the three-way catalytic converter is clogged?

The reactions of a car when the three-way catalytic converter is clogged include: 1. The car experiences difficulty in acceleration, with the engine RPM and vehicle speed struggling to increase; 2. Automatic transmission vehicles are forced to frequently downshift; 3. The engine power decreases, and exhaust emissions exceed the standard; 4. The engine shakes, the fault light comes on, and the car frequently stalls; 5. The exhaust pipe temperature continuously rises, reaching the ignition point of nearby components, which can easily lead to spontaneous combustion. Solutions for a clogged three-way catalytic converter: 1. Remove the three-way catalytic converter and soak and clean it with oxalic acid or toilet cleaner; 2. Replace the three-way catalytic converter; 3. Add gasoline additives and avoid using inferior gasoline and gasoline additives.
