Why Does the Car Make Noise When the Air Conditioner is On?

When the car's air conditioner is turned on, the noise is often caused by moisture or air in the refrigerant of the system. As the refrigerant expands, it produces sound. Below is an introduction to car air conditioner maintenance: 1. Do not adjust the air conditioner vent direction randomly: When using the air conditioner, not paying attention to the direction of the airflow can reduce its effectiveness. Based on the principle that cold air sinks and hot air rises, the correct approach is to point the vents upward when cooling and downward when heating. 2. Regularly start the air conditioner in winter: In some regions where winters are relatively mild, some car owners do not use the air conditioner at all during winter. Prolonged disuse can lead to aging of rubber seals and drying of lubricants on internal components. Regularly starting the air conditioner ensures that all parts are lubricated and maintained in good condition. Therefore, it is best to start the air conditioner at least once a week during winter.

Which gear should be used for climbing slopes in the new Qashqai?

Dongfeng Nissan's new Qashqai can use the S gear for climbing slopes. After completing the action, you can switch back to D gear. The S gear provides stronger power and is generally used when overtaking or climbing slopes that require more power. If the slope is not steep, you can also use D gear for climbing. Here is some additional information: The rear part of the new Qashqai has not changed much overall. While upgrading the internal lamp cavity structure of the taillight assembly, it also adopts a new-style rear bumper design. The large area of black plastic panel is paired with a silver two-stage guard plate, making it look more innovative. In terms of power, only a 2.0L naturally aspirated engine has been found in the application information, with a maximum power of 113kW (154PS), which is 3kW (4PS) higher than the current model. In terms of the system, the new car continues to be equipped with a CVT transmission.

How many kilometers can a 47L fuel tank run?

If a 1.8L displacement car is filled with 47 liters of fuel, it can generally run for over 400 kilometers. On highways, it might run even farther, while city driving with traffic congestion consumes more fuel. However, the distance varies depending on the car model, displacement, road conditions, and driving habits. Not every car, driver, or location will have the same fuel consumption. Below is an introduction to car engines: 1. Engine classification: Based on power sources, car engines can be divided into diesel engines, gasoline engines, electric motors for electric vehicles, and hybrid systems. 2. Engine principles: Common gasoline and diesel engines are both reciprocating piston-type internal combustion engines, converting the chemical energy of fuel into mechanical energy for piston movement and outputting power. Gasoline engines have higher RPM, lighter weight, lower noise, easier starting, and lower manufacturing costs. Diesel engines have higher compression ratios, better thermal efficiency, and superior fuel economy and emission performance compared to gasoline engines.

What are the reasons for sluggish acceleration when flooring the throttle?

Sluggish acceleration when pressing the throttle pedal could be caused by excessive engine oil, overly viscous engine oil, faulty sensors around the engine, or transmission system malfunctions. In vehicles, the engine generates power while the transmission system transfers this power to the wheels. If there's an issue with the transmission system, acceleration problems will occur when depressing the throttle. Below are relevant details: 1. Poor fuel quality: Using low-grade gasoline from unregulated gas stations may lead to incomplete combustion of the air-fuel mixture, triggering the engine warning light. While this doesn't immediately affect driving safety, it can potentially harm the engine. 2. Oxygen sensor failure: The front oxygen sensor monitors the air-fuel ratio under different engine conditions, with the ECU using this data to adjust fuel injection and ignition timing. The rear sensor primarily evaluates the catalytic converter's performance.

Why does the clutch keep getting air when it's not lacking oil?

Here are the reasons why the clutch keeps getting air when it's not lacking oil: 1. Air in the master cylinder: If there is air in the clutch master cylinder, it definitely wasn't bled properly because air in the clutch master cylinder is difficult to remove. If bleeding doesn't work, the master cylinder may need to be replaced. If the master cylinder is new, the air was likely not fully bled. 2. Clutch malfunction: If the clutch is malfunctioning, clutch slippage can cause the engine RPM to increase during acceleration without a corresponding increase in vehicle speed. This leads to issues such as poor acceleration or gear shift jerking. After parking the car and turning off the engine for 5-10 minutes, without pressing the brake, press the start button once or turn the key halfway to the 'on' position without depressing the clutch. The car will perform a self-check after powering on. Wait for 5-10 seconds and observe if the dashboard warning lights turn off, leaving only the engine warning light.

What does the BMW 3 Series 2B63 fault code mean?

BMW 3 Series 2B63 fault code. BMW 3 Series 2B63 fault code: Exhaust and intake VANOS swapped. After swapping the left and right camshaft sensors and checking, it still reports exhaust issue, possibly indicating a faulty exhaust VANOS. BMW 3 Series 2A87 fault: DME exhaust, adjustable camshaft control device adjustment exceeds tolerance range. This fault code is set when the camshaft control fails to reach the target position. Low oil supply pressure can cause the adjustable camshaft control device to exceed the tolerance range. 1) If there is abnormal engine noise, focus on checking whether the camshaft bearing seat is worn. If not, check the DME version number. Program status before 05-09-5xx did not include the VANOS solenoid valve cleaning program. Check if the oil cap insert was lost during maintenance. Check if the oil and oil filter are too dirty. Replace both VANOS solenoid valves if necessary.
