Why does the air conditioning not cool when the car is idling?

Here are the reasons why the air conditioning does not cool when idling: 1. Refrigerant leakage in the air conditioning system: Refrigerant leakage leads to insufficient refrigerant, causing the air conditioning not to cool. The solution is to add refrigerant along with fluorescent dye. After driving the vehicle for a period, use a specialized UV lamp to inspect the air conditioning system. If there are leaks, the dye will glow, allowing you to repair or replace the leaking parts. 2. Low engine speed: When the car is idling, the engine speed is low, which causes the compressor speed to also decrease. Combined with insufficient refrigerant, the instantaneous pressure boost fails to reach the standard state, resulting in excessively low high pressure and the air conditioning not cooling. Observe the sight glass on the dryer tank. If continuous bubbles appear in the sight glass during normal operation, it indicates insufficient refrigerant. If bubble flipping occurs, it means the refrigerant is severely insufficient and needs to be replenished. 3. Expansion valve damage: A damaged expansion valve prevents the system from forming high pressure before the valve, and the high-pressure refrigerant cannot reach 150 Kpa. This results in the evaporator after the expansion valve failing to cool, causing the air conditioning to not cool. Internal wear in the air conditioning compressor leads to the pressure between the compressor and the expansion valve failing to reach 150 Kpa to 200 Kpa, preventing the refrigerant from circulating normally and causing the air conditioning to not cool. If severe internal wear is found in the compressor, replacing the compressor will resolve the issue.

How to Start a Car Without a Key?

Cars without keys can be started in two ways: Button Type: The ignition button is located within easy reach on the center console, hence also known as one-button start; Knob Type: Generally located at the original key slot, but without the need to insert a car key, simply turn the knob to start. Starting without a key, also known as keyless start, is used as follows: 1. Opening and Closing Doors: Normally, when the key is within the effective detection range of about 1.5 meters near the main door, the ID of the key chip will automatically match with the engine's ID. After successful pairing, the car door will open without the need for a key. When the driver leaves the vehicle, the door locks will automatically engage and enter an anti-theft state. However, when the smart key runs out of battery, there is a sensor button on the vehicle's door handle, as well as a keyhole, designed for use in case the smart card is damaged or out of power. 2. Starting and Stopping the Vehicle: When entering the car, the vehicle's detection system will immediately recognize your smart card. After confirmation, the car's computer will enter a working state. At this point, simply press the one-button start button (or turn the knob) inside the car to start the vehicle normally.

What is the fuel tank capacity of the old Jianghuai Refine?

2013 old Jianghuai Refine has 2 models, with a fuel tank capacity of 80 liters. The vehicle is equipped with a 1.8T turbocharged engine, and all models come with a 6-speed automatic transmission (AT) and a 6-speed manual transmission (MT). In the same class, the Jiulong W5-2021 has a fuel tank capacity of 70 liters, and the Fengjing G5-2022 also has a fuel tank capacity of 70 liters. During actual refueling, the amount of fuel may exceed the calibrated capacity. This is because the fuel tank capacity marked by the car manufacturer is from the bottom of the tank to the safe limit, and there is still some space from the safe limit to the tank opening. This space is to ensure that the fuel in the tank can expand when the temperature rises without overflowing the tank's safe space. If the fuel is filled to the tank opening during refueling, the actual refueling amount may be larger than the calibrated fuel tank capacity. If the owner wants to know the remaining fuel in the tank, they can observe the fuel gauge on the right side of the dashboard, which is marked with E and F. When the pointer is close to E, it means the fuel is almost empty, and when it is close to F, it means the fuel is sufficient.

What is the displacement of the BMW M8 Coupe?

The displacement of the BMW M8 Coupe is 4.4T. Factors affecting car displacement: The size of a car's displacement is determined by its engine. Generally, a larger displacement means the engine releases more energy (converting chemical energy from fuel into mechanical energy) per unit of time, resulting in better performance. General car displacement categories: Mini cars have a displacement of ≤1.0L; compact cars range between 1.0-1.6L; mid-size cars range between 1.6-2.5L; executive cars range between 2.5-4.0L; and luxury cars have a displacement of >4.0L.

What causes the Highlander AWD to fail to start when switched to 2AWD?

Highlander AWD failing to start when switched to 2AWD is due to a four-wheel drive system malfunction. Possible causes include a dead battery, lack of fuel, missing antifreeze, or incorrect gear selection. Details are as follows: Dead battery: This can be caused by leaving headlights on for an extended period or the battery reaching the end of its lifespan. Regularly check the battery's condition and replace it promptly if it's no longer functional. Lack of fuel: If the fuel gauge shows the level below the red line, the vehicle naturally won't start. Also, pay attention to the quality of the fuel. Missing antifreeze: Some drivers use water or low-quality antifreeze, which can freeze in extremely cold winter conditions, blocking the entire cooling system and cracking the engine. This prevents the car's water pump from operating, leading to a failure to start and damaging other engine components. Always use or replace antifreeze as needed. Incorrect gear selection: The Highlander must be in P (Park) or N (Neutral) to start. If it's in R (Reverse) or D (Drive), it won't start. Always check the gear position before starting the vehicle.
