Why is there a strange noise when the air conditioner is on?

The reasons for strange noises when the air conditioner is on are as follows: 1. From the radiator fan of the car's water tank: Since the car fan receives the command to turn on the air conditioner, it will operate at high speed. Normally, it only works when the water temperature is high, but it needs to run continuously when the air conditioner is on, which significantly increases the noise. When the fan becomes unbalanced due to dirt accumulation, the noise becomes louder and is accompanied by car body vibration. 2. From the air conditioner blower: When the blower motor bearings are worn or lack lubricating oil, noise will also occur, usually a sharp sound. Another reason is not replacing the air filter element in time, causing it to accumulate dust and become unbalanced, leading to resonance and strange noises. 3. From the noise of the air conditioner compressor belt: When the air conditioner is turned on, the compressor engages, increasing the load on the belt. When the belt is loose or aged, strange noises will occur.

Why Does a Motorcycle Experience Unstable Idling?

There are several main reasons why a motorcycle may experience unstable idling: 1. Carburetor: If the carburetor has not been cleaned for a long time, it can lead to unstable idling. 2. Engine Air Leak: A slight air leak in the engine can also cause unstable idling. The causes of air leaks can vary, such as overly tight valve clearance, poor sealing between the carburetor and cylinder block, or damage to the secondary combustion tube, all of which can result in engine air leaks. 3. Ignition System: If the ignition system is slightly damaged, the vehicle may still start but exhibit unstable idling symptoms similar to those caused by carburetor issues.

Does the Excelle have a rearview mirror heating function?

The Excelle does have a rearview mirror heating function. The switch for the rearview mirror heating is located on the vehicle's air conditioning control panel, shaped like a rectangle with three curved lines and arrows from bottom to top. When the vehicle is powered on or started, simply press the button to activate the rearview mirror heating, which simultaneously turns on the rear window defogging function. The rearview mirror heating function is particularly useful in rainy or snowy weather. When activated, the heater behind the mirror quickly warms the surface, gradually removing rain or fog from the mirror. This eliminates the need for the driver to frequently wipe the mirror manually, thereby reducing driving hazards. How to use the rearview mirror heating function: There are generally two ways to activate the rearview mirror heating function. One is combined with the electric rearview mirror adjustment button—simply rotate the knob to turn it on. The other is located on the air conditioning control panel—press the heating button to activate it. No manual angle adjustment is needed, as there is an adjustment button on the driver's side. Principle of the rearview mirror heating function: After rotating the button, the electric heater behind the rearview mirror glass quickly heats up to a fixed temperature within minutes, typically between 35-60 degrees Celsius. The heat is then distributed across the left and right rearview mirrors. As the temperature rises and evaporation occurs, water droplets on the mirror surface become smaller, and fog gradually disappears, effectively defogging the mirror. However, if the rain is particularly heavy, the effect may diminish and become less noticeable. Precautions for using the rearview mirror heating function: The principle of rearview mirror heating involves adding electric heating wires to the mirror. These wires consume a significant amount of power, so it's essential to ensure the vehicle is running when using this function. Avoid activating the rearview mirror heating while the car is stationary to prevent draining the battery and making it difficult to start the vehicle. Other methods for defogging rearview mirrors include: Opening windows for air circulation: Crack open the side windows slightly to allow air exchange between the inside and outside of the car. This reduces the temperature difference, causing the fog to gradually disappear. Adjusting the car's air conditioning to the appropriate setting can also use warm air from the AC to defog the mirrors.

What are the solutions for automobile exhaust?

Methods for treating automobile exhaust include cleaning the three-way catalytic converter, cleaning the air filter, and performing a deep engine cleaning. The most fundamental approach is to change the vehicle's power source, such as developing electric vehicles and alternative fuel vehicles, which produce little or no polluting gases. Cleaning the three-way catalytic converter: When the engine's air-fuel mixture does not burn completely, a large amount of carbon deposits is produced. These deposits are discharged through the exhaust pipe and adhere to the interior of the three-way catalytic converter. Over time, this can easily lead to clogging, resulting in excessive automobile exhaust emissions. Soaking and cleaning the three-way catalytic converter with an oxalic acid solution, followed by rinsing several times with clean water, can resolve the issue. Cleaning the air filter: The main function of the air filter is to remove particulate impurities from the air. If it is not cleaned or replaced for a long time, the air filter may accumulate many impurities, reducing its effectiveness in filtering suspended particles. This can lead to accelerated engine wear and carbon buildup, resulting in excessive exhaust emissions. Therefore, when the air filter is contaminated to a certain extent, it must be cleaned. Deep engine cleaning: If automobile exhaust emissions still fail to meet standards after cleaning the three-way catalytic converter and air filter, a deep engine cleaning may be necessary. This not only effectively reduces exhaust emissions but also helps maintain the vehicle, significantly improving its operating condition. Management measures: Control at the source by strengthening the new vehicle admission system. New vehicles that do not meet emission standards should be prohibited from leaving the factory or being sold, encouraging automakers to accelerate the development of energy-saving and emission-reducing vehicles. Establish interdepartmental coordination mechanisms. Automobile exhaust management requires multi-departmental collaboration for comprehensive oversight. Regions should establish and improve joint meeting systems for automobile exhaust management, forming a supervision system that includes new vehicle control, fuel quality supervision, regular testing of in-use vehicles, label issuance, network transmission, law enforcement inspections, repair management, and scrapping. Conduct motor vehicle exhaust emission testing. Vehicles that fail to meet standards should be ordered to rectify within a specified period. Those that remain non-compliant after the deadline should be blacklisted, with license plate numbers published by departments such as traffic police, transportation, and environmental protection for elimination. Strengthen automobile exhaust treatment. On the basis of establishing exhaust testing lines, exhaust treatment institutions should be set up to install catalytic purifiers, modify engines, or use cleaning additives for non-compliant vehicles, ensuring exhaust emissions meet standards. The main pollutants in automobile exhaust are carbon monoxide (CO), hydrocarbons (HC), nitrogen oxides (NOx), and lead (Pb).

How to Deal with Water Inside Car Headlights?

Here are the methods to deal with water inside car headlights: 1. Turn on the headlights: The best way to handle fogging inside car headlights is to turn them on. Usually, after the headlights have been on for a while, the fog will dissipate through the vent tube along with the heat, without causing any damage to the headlights or circuits. 2. Use external airflow: If you have a high-pressure air gun or a hair dryer, set it to the cold air setting and blow air over areas in the engine compartment that are prone to moisture accumulation to speed up air circulation and remove moisture. If there is a significant amount of water inside the headlight, it is advisable to carefully inspect the internal components for any damage and replace them promptly if necessary.
