What Causes Fluctuating Idle Speed?

Fluctuating idle speed can be attributed to the following reasons: 1. Dirt from the air and sludge from gasoline can easily cause the throttle to become dirty, leading to poor operation of the idle speed motor. 2. Excessive carbon buildup can result in valves not sealing properly, poor fuel injector atomization, and incomplete combustion. 3. A clogged exhaust pipe can cause poor exhaust flow. 4. Air leaks can lead to insufficient vacuum. 5. Aging wiring or issues with the computer board, though this phenomenon is less likely to occur in the short term. Countermeasures: 1. When the engine idle is unstable, the first step is to adjust the idle speed. 2. If the issue persists after adjustment, check whether the idle jet and idle air jet are clogged. If they are clogged, clean them with gasoline or acetone and use compressed air to blow them clear. 3. If the jets are not clogged, stabilize the engine at a certain speed and listen for air leaks at the intake manifold or the lower gasket of the carburetor. If leaks are found, tighten the screws or adjust the gasket thickness to resolve the issue. 4. If the idle is unstable and accompanied by a decrease in engine power, further inspect the spark plugs, valve sealing performance, and ignition timing. If necessary, perform maintenance or adjustments.

What Are the Reasons and Solutions for a Car Not Starting?

Introduction to reasons why a car won't start: 1. Dead battery: When the car battery is dead, the car won't start. There are many reasons for a dead car battery, such as lack of water in the battery, battery malfunction, or prolonged use of the air conditioning. If the car won't start, the first thing to check is whether there is an issue with the car battery and what the specific problem is, then take it to a 4S shop for repair. 2. Low temperature: In cold winter weather, cars often have difficulty starting. This is because in low-temperature environments, the viscosity and rotation speed of the car's engine oil decrease, leading to reduced ignition energy from the battery and decreased molecular activity. As a result, flammable gases cannot form, making it hard to start the car. If this happens, don't panic—it's not a car malfunction but a normal phenomenon. Try pressing the clutch before starting the car; it might help. 3. Carbon buildup in the car: Carbon buildup in the car's engine can cause many problems, the most common being difficulty starting the car. There are many reasons for engine carbon buildup, such as excessive water in gasoline, poor fuel quality, or poor sealing of the valve seat ring. So if the car is hard to start, check if there is a lot of carbon buildup in the engine. If so, clean it promptly.

What to Do When the Car Won't Start After Driving Through Water

After the vehicle has driven through water, do not attempt to start it. At this point, the car owner needs to push the vehicle out of the deep water area to prevent it from remaining submerged. Never try to restart the engine after driving through water. Immediately call for a tow truck and have the car inspected at a repair shop. Otherwise, it may cause engine damage and void any insurance claims.

What Causes Cylinder Scoring in Automotive Compressors?

Main reasons include lack of lubrication from refrigeration oil or internal malfunctions. More about compressors: 1. Introduction: The automotive AC compressor serves as the heart of the car's air conditioning refrigeration system, responsible for compressing and circulating refrigerant vapor. Compressors are categorized into fixed displacement and variable displacement types. Based on working principles, AC compressors can be divided into fixed displacement compressors and variable displacement compressors. 2. Classification: According to operation methods, compressors are generally classified as reciprocating and rotary types. Common reciprocating compressors include crankshaft connecting rod type and axial piston type, while typical rotary compressors include rotary vane type and scroll type.

How to Dry Wet Car Seats?

If the car seats have covers, remove them immediately as the covers can prevent air circulation. To avoid unpleasant odors and corrosion after the seats get wet from rain, you can clean the seats with cleaning products and then wipe them dry. You can turn on the car's heater to raise the temperature inside the cabin, which helps dry the wet car seats. Frequently open the car windows to maintain ventilation inside the cabin, allowing the wet seats to dry naturally with airflow.
