What Causes the Noise When Turning on the Air Conditioning in a Buick Excelle?

Due to the presence of air or moisture in the system's refrigerant, abnormal noises occur during the evaporation and expansion of the refrigerant. Specific reasons are as follows: Abnormal noises from the engine area when turning on the air conditioning. 1. Metal friction noise caused by the engagement of the compressor's electromagnetic clutch. Lack of lubricating refrigerant oil inside the compressor. When there is insufficient refrigerant oil, the internal piston of the compressor does not receive adequate lubrication, resulting in metal friction noises under the high pressure of the refrigerant. If the electromagnetic clutch itself is faulty or the internal bearings are damaged, abnormal noises will occur. In such cases, the compressor must be replaced. 2. Squeaking noise caused by excessive tension on the air conditioning belt. When the air conditioning is turned on, the system pressure rises rapidly. If there is insufficient refrigerant, it is necessary to first recover the refrigerant from the air conditioning system, evacuate the system, add sufficient refrigerant oil, then recharge the refrigerant, and run the air conditioning for a while to allow the refrigerant oil to circulate fully in the system.

Why is the air conditioning noise particularly loud when the car is running?

The reasons for particularly loud air conditioning noise when the car is running include the following: 1. Abnormal noise from the air conditioning pump: Any issue with either the electromagnetic clutch or the bearings inside the air conditioning pump can cause abnormal noise. The noise from the electromagnetic clutch is mainly caused by wear leading to increased clearance, while the noise from the air conditioning pump bearings is primarily due to insufficient lubrication. In severe cases, this can lead to the air conditioning pump burning out, rendering it unable to perform cooling functions. 2. Dirty or stuck throttle valve: Turning on the air conditioning increases the engine load, requiring the engine to widen the throttle opening to allow more air intake. If the throttle valve has carbon buildup or is stuck, it can cause engine shaking and abnormal noise. 3. Improper tension of the compressor drive belt: If the tension of the drive belt is incorrect, it can cause abnormal noise in mild cases and damage the air conditioning compressor in severe cases. The principle is that if the drive belt is too loose, the electromagnetic clutch will slip; if the drive belt is too tight, the load on the electromagnetic clutch will increase.

What is the fuel consumption of the Exeed TXL 4WD?

The comprehensive fuel consumption of the Exeed TXL 4WD is 6.9-7.6L/100km. There are currently 2 models of the Exeed TXL 4WD available for sale: the 4WD Super Power 2 and the 4WD Super Power 1, both with a comprehensive fuel consumption of 7.6L/100km. The above figures are NEDC comprehensive fuel consumption, which are the fuel consumption data measured under the NEDC test procedure. The actual fuel consumption is higher than this value, ranging from 8.44-8.78L/100km. When driving, the following 5 tips can help reduce fuel consumption: When starting the vehicle, use a low gear, gently press the accelerator, and accelerate slowly. Avoid suddenly stomping on the accelerator, as this can multiply fuel consumption. Light acceleration, light braking, and early braking: When driving, press the accelerator lightly to avoid sudden increases in engine speed and prevent the car from shaking during operation, making the car more fuel-efficient. By anticipating road conditions and adopting slow, uniform acceleration or braking, fuel economy can be improved by up to 20%. Maintain proper tire pressure: Keep the tire pressure at the level recommended by the manufacturer. For every 2 PSI below the recommended value (equivalent to about 0.2 in metric units relative to the standard pressure of 2.4), fuel consumption increases by 1%. Regular vehicle maintenance or inspection: Regular oil changes can reduce carbon buildup (carbon buildup can cause poor ignition, sluggish acceleration, increased fuel consumption, and in severe cases, even cylinder misfires). Regularly check and replace the air filter when dirty, and clean or replace the fuel injectors, spark plugs, and throttle body as per the mileage. Close the windows while driving. Driving with windows open increases wind resistance. The greater the wind resistance, the more resistance the car encounters, requiring more power and thus increasing fuel consumption.

Reasons Why a BMW Shakes During Cold Start but Returns to Normal After a While

Analysis of the reasons why a BMW shakes during cold start but returns to normal after a while can be divided into two scenarios: 1. If the car runs normally when warm, it is likely caused by excessive carbon buildup in the intake manifold: Because gasoline atomization is poor during cold starts, the fuel injectors spray gasoline, some of which is absorbed by the carbon deposits. Only a portion of the gasoline enters the cylinders, resulting in a lean mixture (more air, less fuel). 2. When the car has been parked for a while, it may shake slightly during cold starts and when idling in neutral. The reasons are as follows: 1. Low ignition energy causing shaking: When the engine temperature is too low, both fuel and lubricant temperatures are low. During a cold start, a richer air-fuel mixture is required, which in turn demands higher ignition energy. Excessive spark plug gap, aging ignition coils, or high-voltage coils can all lead to reduced ignition energy, causing the car to shake. 2. Incorrect air-fuel mixture ratio causing shaking: During a cold start, if certain engine sensors or their signals have significant errors, the ECU may make incorrect judgments. This can result in inaccuracies in fuel injection timing and ignition timing control, leading to engine shaking. 3. Uneven cylinder conditions causing engine shaking: In multi-cylinder engines, significant differences in ignition energy between cylinders, as well as varying degrees of wear on pistons and piston rings, can cause inconsistent compression ratios. This leads to uneven power output from the engine, resulting in shaking.

Can a car be driven on the road with only compulsory traffic insurance?

A vehicle can be driven on the road with only compulsory traffic insurance, as it is the only insurance mandated by the state, and having it is necessary for legal road use. Otherwise, according to the "Road Traffic Safety Law," the traffic management department of the public security authorities shall detain the motor vehicle, notify the party to provide the corresponding license, mark, or complete the necessary procedures, and may issue a warning or impose a fine of not less than 20 yuan but not more than 200 yuan. Compulsory Traffic Insurance for Vehicles: The full name of compulsory traffic insurance is "Compulsory Liability Insurance for Motor Vehicle Traffic Accidents." It is a mandatory liability insurance where the insurance company compensates for personal injuries, deaths, and property losses of victims (excluding vehicle occupants and the insured) caused by road traffic accidents within the liability limits. The premium is based on the nationally unified standard rates. However, the price of compulsory traffic insurance varies for different vehicle types, primarily influenced by the number of car seats. Compared to the more than 20 exemption clauses in commercial third-party insurance, compulsory traffic insurance covers a much broader range, including losses caused by intentional acts of the victim, the insured's own property losses, related arbitration and litigation costs, and some indirect losses caused by the accident. Moreover, regardless of whether the insured vehicle is at fault in the accident, compulsory traffic insurance will compensate within the liability limits without any deductible or exemption. Introduction to Electronic Insurance Policies An electronic insurance policy refers to a digital policy issued by an insurance company using digital signature software and corporate digital certificates that comply with the PKI system, bearing the electronic signature of the insurance company. An insurance policy, abbreviated as a policy, is the official written proof of the insurance contract between the insurer and the insured. The policy must fully record the rights, obligations, and responsibilities of both parties to the insurance contract. The content recorded in the policy serves as the basis for both parties to fulfill the contract. The policy is proof of the establishment of the insurance contract. Advantages of Electronic Insurance Policies: Saves paper resources, eliminating the need to print insurance proof marks on paper; Saves time and is convenient, unrestricted by time or location, with information universally accessible online anytime, quickly and easily; Allows for reissuance and resending, eliminating worries about loss. If a paper version is needed offline, it can also be printed or mailed; Facilitates management, as electronic standardization makes it easier for insurance companies and traffic police departments to manage the insurance information of various vehicles.
