Reasons and solutions for the Kia K2 air conditioner not cooling: 1. Insufficient or low refrigerant: A common reason for a car air conditioner not cooling is insufficient or low refrigerant, which may be caused by minor leaks. The solution is to add refrigerant. However, note that if adding from the low-pressure side, do not invert the refrigerant bottle; if adding from the high-pressure side, do not start the engine. 2. Loose drive belt of the car air conditioner compressor: Car cooling relies on refrigerant, and refrigerant transmission depends on the air conditioner compressor, with the drive belt being a crucial moving part. If the drive belt is loose, the compressor may slip during operation, reducing transmission efficiency, lowering the compressor's speed, and decreasing refrigerant delivery, leading to the air conditioner not cooling. If the compressor drive belt is too loose, it should be tightened. If it cannot be turned by hand, it indicates the belt is too tight and should be loosened slightly. If tightening is ineffective or the belt shows cracks or aging, replace it with a new one. 3. Unqualified refrigerant and refrigerating oil: Excessive impurities in the refrigerant and refrigerating oil can clog the car air conditioner's filter, causing it not to cool. This increases resistance and reduces refrigerant flow to the expansion valve, resulting in insufficient cooling. In this case, use qualified refrigerant for repairs, as it plays a key role in the car air conditioner's performance. 4. Moisture infiltration in the refrigeration system: If moisture enters the car air conditioner's refrigeration system, it can cause insufficient cooling or no cooling. If this is the issue, replace the desiccant or dryer in the air conditioner, then evacuate the system and refill it with the appropriate amount of new refrigerant.

What should be the speed limit in kilometers per hour when turning on a curve?

The speed should be controlled at 30 km/h when turning on a curve. Basic principles of turning: When turning, the car will generate centrifugal force. When going uphill, the speed is slower, the centrifugal force is weaker, and the center of gravity of the car shifts backward, reducing the degree of understeer and making the direction of the car easier to control. When going downhill, the situation is the opposite. Due to the higher speed, the centrifugal force is stronger, and the center of gravity shifts forward, increasing the degree of understeer. Techniques for turning: Maintain an "outside-inside-outside" turning path. The safest and most time-efficient route when turning is "outside-inside-outside." When driving at high speed, before turning, you should first drive along the outer lane, then move to the inner lane in the middle, and then cut back to the outer lane.

What does motorcycle CDI ignition mean?

Motorcycle CDI ignition stands for Capacitor Discharge Ignition. Introduction to CDI: CDI, or Capacitor Discharge Ignition, is a new type of engine ignition device that uses a capacitor and thyristor diode circuit to replace mechanical forms such as contact switches, achieving contactless ignition, which is relatively safer. Advantages of CDI: CDI is a relatively simple electronic circuit. Its working principle essentially simplifies the structure of the magneto, thereby reducing costs and improving the reliability of the ignition process. Therefore, the majority of motorcycles use CDI.

How many points are deducted for driving a small car for more than 4 hours?

Driving a small car for more than 4 hours will result in a deduction of 6 points. The penalty for driving continuously for 4 hours without rest is divided into two scenarios, and both are relatively severe. Driving medium-sized or larger passenger vehicles or hazardous material transport vehicles: For driving medium-sized or larger passenger vehicles or hazardous material transport vehicles continuously for more than 4 hours without stopping to rest or stopping for less than 20 minutes, 12 points will be deducted at once. Driving motor vehicles other than medium-sized or larger passenger vehicles or hazardous material transport vehicles: For driving motor vehicles other than medium-sized or larger passenger vehicles or hazardous material transport vehicles continuously for more than 4 hours without stopping to rest or stopping for less than 20 minutes, 6 points will be deducted at once.

What Causes the Clicking Sound When a Car Fails to Start?

The reasons why a car makes a clicking sound and fails to start are as follows: Dead Battery: A dead battery is one of the most common reasons a car won't start. Apart from the battery's quality and lifespan, improper usage by the owner, such as forgetting to turn off headlights when parked or using too many external electrical devices, often leads to battery drain. When a car fails to start due to a dead battery, symptoms usually include the starter not working or turning over weakly when attempting to start the engine. Smart Key Battery Drain: This issue is specific to cars with a push-button start feature. If the car key is nearby but pressing the start button doesn't work, and the smart key warning light on the dashboard remains lit, the smart key's battery is likely drained. Some models with push-button start also retain a traditional key ignition design, allowing the car to be started with the key when the smart key's battery is dead.

Is a Fire Extinguisher Required for Vehicle Inspection?

Vehicle inspection requires a fire extinguisher. Both the vehicle's fire extinguisher and warning triangle are mandatory items during the annual inspection. Some vehicles do not come equipped with a fire extinguisher upon leaving the factory. Introduction to Vehicle Fire Extinguishers: Vehicle fire extinguishers are specifically designed for automotive fire suppression. They include two main types: Non-pressurized hanging ultra-fine dry powder automatic fire extinguishing devices for vehicles, and miniature pressurized hanging ultra-fine dry powder automatic fire extinguishing devices for vehicles. Types of Vehicle Fire Extinguishers: For automotive fire protection, portable fire extinguishers are predominantly used. The main types of vehicle fire extinguishers available in the market include: aerosol fire extinguishers, dry powder fire extinguishers, ultra-fine dry powder fire extinguishers, carbon dioxide fire extinguishers, and water-based fire extinguishers.

What does it mean when the external request MIL light indicates a fault?

External request MIL light indicating a fault means there is a problem with the vehicle. The automotive fault code MIL stands for Malfunction-Indicator-Lamp, which refers to the malfunction indicator light. Solutions for MIL light fault: When the vehicle's malfunction indicator light comes on, if obvious faults in the fuel system, air intake system, or electrical system are found during engine inspection, they can be resolved by yourself. If no obvious faults are detected and normal driving is not affected, you can choose an appropriate time to visit a repair station. If the existing fault affects normal driving, you must immediately go to a repair station for maintenance and avoid attempting blind repairs on your own. Introduction to the malfunction indicator light: The malfunction indicator light is located on the instrument panel; its color is generally red (refer to the vehicle manual for specifics). The malfunction indicator light stays on for 2 seconds before turning off; it lights up when the electronic fuel injection system detects a fault; for general faults, the malfunction indicator light remains on.
