How to Turn on the Car Air Conditioner in Winter?

When turning on the car air conditioner in winter, adjust it to the external circulation mode. Below is a relevant introduction to car air conditioning: 1. Air Conditioning Layout: Different types of air conditioning systems have varying layout methods. Currently, most cars widely adopt the integrated heating and cooling air conditioning system. Its layout involves assembling components such as the evaporator, heater core, centrifugal blower, and control mechanism into one unit, referred to as the air conditioning assembly. 2. Air Conditioning Components: Modern air conditioning systems consist of a refrigeration system, heating system, ventilation and air purification devices, and a control system. Generally, a car air conditioner mainly includes components such as the compressor, electronically controlled clutch, condenser, evaporator, expansion valve, receiver-drier, piping, condenser fan, vacuum solenoid valve, idle speed controller, and control system. The car air conditioning system is divided into high-pressure and low-pressure lines. The high-pressure side includes the compressor output side, high-pressure lines, condenser, receiver-drier, and liquid lines; the low-pressure side includes the evaporator, accumulator, suction line, compressor input side, and compressor oil sump.

Why does the chassis make a crackling sound after the car is turned off?

After the car is turned off, the crackling sound from the chassis is caused by the cooling of the exhaust pipe's three-way catalytic converter, which produces the sound due to thermal expansion and contraction. This is a normal phenomenon and nothing to worry about. The three-way catalytic converter is a crucial purification device in the exhaust system. Its main function is to convert the three harmful substances—CO, HC, and NOx—into harmless substances. Here are some details about the three-way catalytic converter: 1. Composition: The three-way catalytic converter contains platinum, rhodium, and palladium. 2. Functions of each element: Platinum, rhodium, and palladium effectively catalyze nitrogen oxides and particulate matter in the exhaust, so vehicles equipped with a three-way catalytic converter have much less noticeable exhaust odor.

What are the precautions for novice drivers when driving the Geely Xingrui?

Precautions for novice drivers when driving the Geely Xingrui are as follows: 1. Warm up the car in advance: The Geely Xingrui 2.0T is equipped with an advanced one-key ignition start system. Even with one-key start, the car still needs to be "warmed up," although the current warming process differs from the traditional idle warm-up. After getting in the car, first adjust the seat to a suitable position and fasten the seatbelt. 2. Speed control: During the "break-in period," it is best to keep the speed between 40 km/h and 100 km/h. Driving at excessive speeds places a greater burden on the vehicle compared to moderate speeds. Always accelerate gradually and avoid maintaining the same speed for extended periods. During the first 300-500 kilometers of a new car, frequent sudden acceleration or deceleration can cause the car to adapt poorly.

Why is the Natural Gas Vehicle Lacking Power?

Natural gas vehicles often experience insufficient power primarily due to the lack of engine modifications during the conversion process. When converting a vehicle to run on natural gas, the engine is typically left unchanged to accommodate both fuel types (gasoline and natural gas). As a result, the vehicle's power output when using natural gas is usually reduced by 5-15% compared to gasoline. Solutions to address the lack of power in natural gas vehicles are as follows: 1. Solution 1: Increase the ignition timing by 12 to 17 degrees from the original setting. Natural gas itself has stable chemical properties, a higher ignition point than gasoline, and burns slower. Advancing the ignition timing can help reduce power loss. 2. Solution 2: Upgrade to a high-energy ignition system by installing a better ignition coil. Since the flame propagation of natural gas is slower than gasoline, this modification ensures more complete combustion of natural gas, thereby improving vehicle power.

What Does Used Car Refurbishment Mean?

Used car refurbishment refers to the process of thoroughly inspecting a purchased used car for any issues and addressing any problems found. Below is relevant information about purchasing used cars: 1. Solutions for issues with used cars: According to Chinese used car laws, general used cars do not come with a quality guarantee, but it is required to sign a contract during the transaction. The contract should clearly describe any existing problems with the used car, such as if the car has been involved in a major accident or is a repaired vehicle from a significant collision. If the seller conceals the true condition of the vehicle and fails to disclose it in the contract, the buyer can use the contract to resolve issues through market coordination. If the market does not intervene, the buyer can apply for arbitration or seek legal resolution. Commercial insurance can help recover some losses through policy cancellation. 2. Ways to purchase used cars: Used car trading markets offer the best hands-on experience. Online used car platforms provide the widest selection of vehicles. Personal car listings offer the most favorable prices.

During the appeal and litigation period, the original ruling shall be suspended. When the ruling is revoked or execution begins, the security deposit shall be refunded according to regulations. For those who do not carry their motor vehicle driver's license with them, regardless of whether the driver violates the law during the driving process, they cannot continue to drive the vehicle. The traffic management department of the public security organ shall impound the motor vehicle and notify the driver to provide the driver's license. Different treatments shall be applied based on the different circumstances of providing the driver's license.
