What should the indoor car air conditioning temperature be set to in winter?

In winter, the most suitable temperature setting for car air conditioning is between 18℃ and 20℃. Here is relevant information about car air conditioning: 1. The function of car air conditioning is to adjust and control the temperature, humidity, air cleanliness, and airflow inside the vehicle to an optimal state. It also provides a comfortable environment for passengers, reduces travel fatigue, creates good working conditions for the driver, and serves as a crucial ventilation device for ensuring safe driving. 2. Car air conditioning consists of components such as the compressor, condenser, evaporator, expansion valve, receiver-drier, and piping. 3. Car air conditioning generally includes cooling devices, heating devices, and ventilation devices. These combined systems make full use of the limited space inside the vehicle, featuring a simple structure and ease of operation.

What is the background color of the driver's license photo?

The background color of the driver's license photo is white. According to the "Road Traffic Safety Law of the People's Republic of China," the driver's license photo must be one inch in size and a recent color frontal headshot taken within six months prior to the application for the driver's license. If corrective lenses are required, glasses must be worn during the photo session. The specific requirements for the driver's license photo are as follows: 1. The photo must be a straight-edged, frontal, color, single-person, half-length ID photo without a hat, scarf, uniform, or tinted glasses. For individuals with long hair, both ears should be visible, and the head or face should not have any tilting, turning, heavy makeup, or accessories that may affect facial feature recognition. 2. The photo dimensions should be 32mm × 22mm, with a head width of 14mm to 16mm and a head length of 19mm to 22mm.

What to Do If the Car Idles High After Cleaning the Throttle Body?

Solutions for high idle speed after cleaning the throttle body: 1. Loosen the throttle body, adjust the screw to bring the engine to a lower stable speed, and place the screwdriver on the idle screw; 2. When the engine is about to stall, turn out the idle screw to reduce the engine speed from high to lower; 3. Repeat the process until the throttle opening is small, then close the throttle body. Situations where the car idles include: 1. When the vehicle is parked and the engine is started, the lower stable speed of the engine is called parking idle; 2. During gear shifting, if the accelerator pedal is not pressed or is released while driving, maintaining a small throttle opening with the engine speed matching the parking idle is called driving idle.

What is used to clean car spark plugs?

Car spark plugs should be cleaned with blue toilet cleaner, the method is as follows: Soak the spark plug ignition electrode directly in pure toilet cleaner and you will see a large amount of bubbles produced, which is the chemical reaction caused by carbon deposits encountering the toilet cleaner. Place it in a ventilated environment for 10 minutes, and after the bubbles gradually decrease, remove it. If there are still black carbon deposits, you can soak it for a while longer, then rinse it with white vinegar. Do not rinse with water, just wait for it to air dry. Spark plugs are mainly composed of a terminal nut, insulator, terminal stud, center electrode, side electrode, and shell. How spark plugs work: The spark plug ground electrode is connected to the metal shell, which is threaded into the engine block through the cylinder head. The insulator mainly serves to isolate the metal shell and the central electrode. The terminal nut is the part of the spark plug that contacts the high-voltage coil. After the current passes through the terminal nut and the central electrode, it breaks down the medium between the central electrode and the ground electrode to produce a spark, thereby igniting the air-fuel mixture in the cylinder.

What Causes the Abnormal Noise When the Car Starts?

Issues that may cause squeaking noises when the car starts are as follows: 1. Check if the timing belt is broken or has frayed edges. 2. Inspect whether the starter is misaligned or if the belt connected to the starter is aged or curled. 3. Examine the idle motor. 4. Determine the noise within the cylinder block, which is likely related to the car's starting system. Methods to identify car noises are as follows: 1. Correctly distinguish between normal and abnormal noises: Normal vibration sounds from various system components, such as engine surface noise, gear impact sounds during gear shifts, intake and exhaust sounds from gas-operated sources, and gear meshing noises, are all considered normal. Abnormal noises can be categorized into minor, moderate, and severe based on their impact on car performance. Minor noises, such as sparking from high-voltage electricity leakage or slight looseness in rolling bearings, are generally low in volume, cause minimal wear on parts, and show no significant changes over a long period. Such issues can be tolerated without immediate repair. 2. Moderate noises, such as those from flywheel bearings or clutch release bearings, significantly affect car performance but can be temporarily tolerated. These noises are usually louder and indicate greater part wear, necessitating timely repairs. If such noises occur during driving, they can be temporarily ignored. Severe noises, such as loud sounds from crankshaft or connecting rod bearings accompanied by a drop in oil pressure, significant gear clashes in the transmission, or strong vibrations from the differential, severely impact the car and may cause or have already caused serious part damage. These issues require immediate attention, and the car should be stopped for inspection. Continuing to drive under such conditions can lead to major mechanical failures. 3. When diagnosing abnormal car noises, ensure good listening conditions and minimize interference from other noises to avoid misjudgment. It's helpful to amplify or reduce the noise intentionally—for example, using a screwdriver or other metal rod as a stethoscope to amplify the noise or employing single-cylinder cut-off to reduce it for better diagnosis. The diagnostic environment should be quiet, with minimal human interference.
