What is the normal pressure for a car air conditioner?

The normal high pressure for a car air conditioner is between 1.3 and 1.7 MPa, while the low pressure ranges from 0.15 to 0.25 MPa. Below is relevant information: 1. Working principle: The car air conditioning refrigeration system consists of a compressor, condenser, liquid storage dryer, expansion valve, evaporator, and blower. These components are connected by copper (or aluminum) pipes and high-pressure rubber hoses to form a sealed system. When the refrigeration system operates, the refrigerant circulates in different states within this sealed system. Each cycle involves four basic processes: compression, heat dissipation, throttling, and heat absorption. These four processes repeat continuously to achieve the goal of lowering the air temperature around the evaporator. 2. Air conditioning maintenance: In summer, do not immediately activate the internal circulation when entering the car. Instead, first open the windows for ventilation and turn on the external circulation to expel the hot air. Only after the cabin temperature has dropped should you switch to internal circulation. The direction of the air vents should not be adjusted arbitrarily. According to the principle that cold air sinks and hot air rises, the correct approach is to point the vents upward when using the air conditioner and downward when using the heater. Do not leave the air conditioner running for extended periods, as prolonged use can increase the pressure on the condenser, causing wear and tear on the refrigeration system. The air conditioner is already a heavy load on the engine, which itself is a heat source, especially in hot weather. Do not turn off the engine before turning off the air conditioner, as this will cause the engine to start with the air conditioner's load during the next ignition, potentially damaging the engine. Therefore, always turn off the air conditioner before shutting down the engine, and wait two to three minutes after starting the car for the engine to be properly lubricated before turning on the air conditioner.

How to Modify a Car to Improve Power?

The principle of lowering the intake air temperature is that colder air is denser, meaning more mass of air will be drawn into the engine cylinders to mix with fuel under the same volume. Replacing the exhaust pipe with one that has a larger diameter and faster flow can improve the smoothness of exhaust gas expulsion, while also enhancing the exhaust sound. Many people choose to replace spark plugs to boost car power, as most modern cars use a high-voltage ignition system without a distributor. Using high-energy, stable spark plugs, well-mixed air-fuel mixture, high compression ratio, high-quality gasoline, and reducing vehicle weight can increase power by 10%.

How to Handle Overdue Inspection for Exempt Vehicles?

If an exempt vehicle fails to apply for the inspection mark on time, the owner should promptly submit a re-inspection application to the traffic police department. Address any overdue inspection violations, pay all fines, and apply for the inspection compliance mark. Otherwise, the longer the delay, the harsher the penalties. Once it is discovered that the annual inspection date on the vehicle registration certificate has expired, the best course of action is to immediately proceed with the overdue inspection. To apply for the inspection compliance mark, you will need to bring the vehicle registration certificate, original ID card, and a copy of the compulsory traffic insurance policy. Additionally, ensure that all vehicle violations have been resolved.

What to Do When a Car is Slipping and Can't Get Out of a Ditch?

Place some bricks or wood in front of or behind the drive wheels of the vehicle to increase the friction of the wheels. You can call for road rescue services by dialing the rescue hotline and use a rescue vehicle to free the stuck car. If equipped with a winch, you can use the winch to pull the vehicle out of the predicament. Avoid continuously accelerating abruptly or applying sudden throttle, as this will not help the vehicle escape and may only worsen the situation, making rescue efforts more difficult and inconvenient.

How to Drain the Washer Fluid and Replace It with Antifreeze?

Find the washer fluid spray switch, press and hold the switch to spray out the summer washer fluid until the spray nozzle stops spraying. After the washer fluid is completely sprayed out, open the car's front hood. Once opened, locate the washer fluid reservoir, which has a blue cap. Open the washer fluid reservoir cap and replace it with antifreeze. If the washer fluid reservoir is half full when replacing, adding a bottle of antifreeze washer fluid will reduce the antifreeze effect of the washer fluid.
