What Causes Noise in Car Air Conditioning?

The causes of noise in car air conditioning can be divided into internal and external noises within the air conditioning system. Below are detailed explanations and solutions: 1. Internal noise in car air conditioning: Internal noise mainly comes from the dashboard area, with the following possible causes: 1. A sound similar to flowing water is heard from the glove box when the air conditioning is turned on. This is the normal operation of the air conditioning expansion valve. 2. Noise within the air conditioning ducts. The air filter has not been replaced for a long time, or there are foreign objects like leaves in the ducts. Solution: Open the air filter cover under the passenger side toolbox, cover it with a gauze bag, start the car, and set the fan to the highest setting to blow out the foreign objects. Alternatively, a repair shop can use high-pressure air to remove the objects. 3. Air or moisture in the refrigerant inside the air conditioning compressor, causing noise during refrigerant evaporation and expansion. Solution: Extract and replace the refrigerant. 2. External noise in car air conditioning: 1. When the compressor lacks lubricating oil or the oil is used improperly, severe noise may occur inside the compressor, potentially leading to wear and failure. Solution: In such cases, check if the clutch is slipping, inspect the drive belt, and ensure the lubricating oil is used correctly. 2. The compressor electromagnetic clutch is another common source of noise. The compressor often operates under high load, shifting from low to high speeds, placing high demands on the electromagnetic clutch. Additionally, the clutch is usually installed close to the ground and frequently exposed to rain and dirt. If the bearings inside the clutch are damaged, noise will occur. Solution: First, check the air conditioning belt to confirm if the mounting screws are loose, if the belt is oily, or if it is worn. If the electromagnetic clutch is faulty, it should be replaced. 3. Check if the engine is leaking oil. Solution: Top up the engine oil.

Can the Ruichi EC35 II remove the speed limit?

No, the speed limit cannot be removed as it constitutes illegal modification. Below is the relevant introduction to the Ruichi EC35II: 1. Exterior: The Ruichi EC35II still maintains its practical microvan attributes. With body dimensions of 4500*1680*1985 (mm), the vehicle doesn't appear large from the outside. However, its cargo compartment volume is 4.8m³, offering high practicality. 2. Battery: The EC35II is equipped with a Santon ternary lithium battery, with a capacity of 42.04kWh and an energy density of 140Wh/kg. 3. Interior: In terms of the interior, the gear shift knob, center console, and instrument panel remain consistent with the previous generation. The overall design is somewhere between passenger cars and trucks, without appearing too outdated.

Is It Normal for the Fueling Amount to Exceed the Fuel Tank Capacity?

It is normal for the fueling amount to exceed the fuel tank capacity. Below are specific details about automotive fuel tanks: 1. Labeled capacity is the safe volume: Most fuel tanks indicate a safe volume, which is generally about 10% less than the actual capacity. During the design of the fuel tank, considering the thermal expansion and contraction characteristics of fuel, a certain space must be left inside the tank after filling to the rated volume to protect driving safety and prevent excessive internal pressure. Overfilling can damage the carbon canister, while underfilling leaves too much empty space, causing fuel to evaporate and be lost as vapor. 2. The fuel gauge cannot accurately reflect the remaining fuel: One cannot rely solely on the fuel gauge on the car dashboard, as it provides only a qualitative indication rather than a quantitative measurement of the remaining fuel in the tank. The relationship between the fueling amount and the distance traveled cannot be used to judge fuel consumption because road conditions, speed, traffic congestion, air conditioning usage, vehicle load, fuel leakage, and fuel quality all directly affect fuel consumption.

Is it okay to leave the parking ventilation on all the time?

It is not advisable to use the parking air conditioning for too long. It is generally recommended to ventilate every 3-4 hours. Here is an introduction about leaving the parking air conditioning on all the time: 1. Increase the load on the refrigeration system: It is not good for health. You can turn it off first and then turn it on again after a while. 2. Do not sleep in a closed car with the air conditioning on: Because the ventilation in the car is poor, the carbon monoxide emitted by the engine may seep into the car, causing carbon monoxide poisoning. 3. Internal and external circulation switch: When external circulation is used, the air conditioning draws air from outside the car. Internal circulation means the air inside the car is recirculated. Setting the temperature too low can affect your health, so the air conditioning temperature should be adjusted appropriately. The most comfortable temperature for the human body is 20℃ to 25℃. If it exceeds 28℃, people will feel stuffy and hot.

What is the weight of the BMW 5 Series?

The curb weight of the domestically produced BMW 5 Series is: 1740KG. Here are the relevant configurations: Exterior: The BMW 5 Series adopts an "open-eye" design, giving a sharp and domineering impression. The large double-kidney grille connects with the headlight units, further expanding the visual width and enhancing the impact. Notably, the grille of the M Sport package is painted black, while the Luxury package features a silver grille. Exterior: The BMW 5 Series comes standard with LED high/low beam headlights across the lineup. However, for the 525Li M Sport package, features like adaptive headlights and automatic high/low beam switching require optional upgrades. The side profile of the BMW 5 Series is quite classic, with the imported standard wheelbase model having a wheelbase of 2975mm, while the domestically produced long-wheelbase version measures 3108mm. The practical significance of the "L" designation can be clearly seen from the proportion of the front and rear doors.

How many meters within a narrow road is parking prohibited?

Parking is prohibited within 50 meters of a narrow road with a width less than 4 meters. Here is additional information: 1. No-parking zones: Parking is not allowed in sections with no-parking signs or markings, sections with isolation facilities between motor vehicle lanes and non-motor vehicle lanes or sidewalks, crosswalks, and construction areas. Parking is also prohibited within 30 meters in front of bus stops, emergency stations, gas stations, fire hydrants, or fire stations, except when using these facilities. 2. Precautions: Doors should not be opened or passengers should not board or alight before the vehicle comes to a complete stop. Opening or closing doors should not obstruct the passage of other vehicles or pedestrians. When parking on the roadside, the vehicle should be close to the right side of the road, and the driver should not leave the vehicle. The vehicle should depart immediately after passengers board or alight or goods are loaded or unloaded. City buses are not allowed to stop to pick up or drop off passengers outside designated bus stops.
