How to Determine the Proper Amount of Car Air Conditioning Refrigerant?

From the sight glass, observe that the refrigerant is transparent, not cloudy, free of bubbles, and flows smoothly. When increasing or decreasing the engine speed, a small number of bubbles may appear. When the refrigerant is at the proper amount, the refrigerant remains transparent regardless of engine speed, with no oil traces at pipe connections. The high-pressure side should feel hot to the touch, with a temperature between 50°C and 70°C, and there should be a noticeable temperature difference between the high and low-pressure sides, indicating the refrigerant is at the proper amount. Below are methods to determine insufficient refrigerant in the car air conditioning system: 1. Insufficient refrigerant can be observed from the sight glass on top of the dryer. When the air conditioning is operating normally, if continuous, slow bubbles are observed through the sight glass, it indicates insufficient refrigerant. If obvious bubble turbulence is seen, it indicates a severe shortage of refrigerant. Check the high and low-pressure side pressures during normal operation; both should be low. In this case, the cooling effect is poor. 2. After the air conditioning has been running normally for a while, the air blown onto the body should feel cool and quickly reach the set temperature. If the compressor starts and stops frequently and the cooling effect is poor, refrigerant may be needed.

What are Simulation One and Simulation Two for?

Simulation One and Simulation Two serve the following purposes: 1. Simulation One: Sitting in a seat similar to a car, conducted in a classroom format. You need to bring the form for Subject Two reservation, along with your ID card and the card for paying the coach. Once the time is up, you can sign and leave. 2. Simulation Two: It's like driving a real car but in a gaming console format, playing for two hours. You need to bring your ID card and the form for Subject Two reservation. Once the time is up, you can sign and leave. Additional Information: Driver's License: The full name of a driver's license is the motor vehicle driving license, also known as a 'driver's license.' It is a certificate required by law for individuals who drive motor vehicles. Driving a motor vehicle requires certain driving skills. Those lacking these skills may cause traffic accidents if they drive recklessly. Generally, individuals cannot drive on the road without a license. However, for those who have mastered safe driving techniques, the document that permits them to drive on the road is the 'driver's license.' This indicates that a driver's license is a 'permit.'

Why does the throttle suddenly fail to accelerate while driving?

If the vehicle suddenly fails to accelerate during normal driving, it may be caused by excessive carbon deposits. Due to carbon buildup, localized high temperatures can cause the combustible mixture to ignite prematurely before the spark plug fires, a phenomenon commonly known as detonation. This disrupts the normal operation of the engine, causing not only vibrations but also a lack of power when stepping on the accelerator, making the vehicle feel sluggish. Below are the steps to address sudden loss of acceleration in a car: 1. Check the fuel tank pump to see if it is functioning properly. The fuel pump motor should produce a sound. If the fuel pump fails to supply fuel normally, it can lead to insufficient vehicle power. 2. Inspect the fuel filter to ensure it is working well and check for leaks or blockages. If the leak is severe, starting the vehicle could potentially ignite it due to static electricity. 3. Examine the intake pipe for any debris blockages. Remove the air filter to check for water ingress, and replace the air filter if necessary. 4. Verify the correctness of the valve timing and ensure the intake and exhaust pipes are tightly sealed. You can clean the throttle body or add a cleaning-type fuel additive (fuel system cleaner) to the fuel, which can help remove some carbon deposits.

Can You Drive with One Headlight Broken? What's the Fine?

No. Driving with a broken headlight is punishable. According to Article 58, Section 17 of the Road Traffic Safety Regulations, operating a motor vehicle with incomplete safety facilities or components that do not meet technical standards, posing safety hazards, will result in a fine. Below is relevant information about automotive lights: 1. Position lights: Position lights indicate the width of the vehicle. Similarly, a circle represents the light, and a horizontal line represents the light beam, which spreads to both sides. They are typically used when night is just falling. 2. Front and rear fog lights: A circle represents the light, a horizontal line represents the light beam, and a curve represents fog. In foggy conditions, light doesn't travel far, so the symbol has a curve blocking the light. If the light beam is at the front, it's a front fog light; if at the rear, it's a rear fog light. They are usually used in rain, fog, or snow, and in extreme weather, it's best to turn on the fog lights rather than the hazard lights.

What to Do When the Car Air Conditioner Is Not Cooling?

Insufficient refrigerant due to low refrigerant levels. The primary cause is often minor leaks in the system. If there is insufficient refrigerant in the air conditioning system, the amount of refrigerant sprayed into the evaporator from the expansion valve will correspondingly decrease, leading to reduced heat absorption during evaporation in the evaporator and consequently diminished cooling capacity. Below is information regarding why a car air conditioner may not cool properly: 1. Air in the system can also cause insufficient cooling. Once air enters the air conditioning system, it can result in excessively high pressure in the refrigerant lines or poor refrigerant circulation, both of which can lead to inadequate cooling. This is mainly due to compromised system sealing or incomplete vacuuming during maintenance. 2. Excessive refrigerant can also cause insufficient cooling. Overcharging the refrigerant, typically occurring during maintenance, can lead to this issue. The proportion of refrigerant in the air conditioning system must meet specific requirements; if it exceeds the optimal level, it can negatively affect heat dissipation, where more heat dissipation means greater cooling capacity. 3. If the compressor is damaged and cannot engage, the air conditioner will not cool. If the refrigerant is sufficient but the air conditioner still fails to cool at all, the compressor may have stopped working, necessitating repair or replacement.
