Talking about automobile air conditioning

Air conditioning and headlights are indispensable equipment in automobile structure. Turn on the air conditioner when it is hot in summer. It's cold in winter. Turn on the air conditioner. So air conditioning is very important for both drivers and passengers. The headlights are even more important. At night, you need car lights to watch the road, show the way and brake. So today we will talk about some knowledge about air conditioning and car lights.

(1) air conditioner

(1) Check the cooling air volume regularly.

The focus of air conditioning inspection is whether there is air conditioning in the air conditioner. Continuous operation under the condition of insufficient cooling air will lead to compressor failure. Please check it irregularly, observe and judge with your eyes, and observe the cooling air directly from the small display window set in front of the engine room. This part is the part where the gas compressed by the compressor becomes liquid. If there is transparent liquid, it can be confirmed as cooling air. Press the belt driving the compressor with your fingers and adjust it to 1cm bend. This unpleasant smell can be eliminated by special chemical synthesis agents.

Check the amount of cooling gas, and put the air conditioner in the starting state. Start the engine and turn on the air conditioner switch. Air conditioning temperature setting. Set it at the lowest temperature, that is, the temperature at which the air conditioner can run continuously, and open the window. We need to go to the engine room to start the inspection, so please fix the open hood. This is the glass hole on the side. If the inside is transparent, it means there is plenty of air. If you see a lot of bubbles, it means it is a little insufficient. If you can only see fog, you must repair it immediately. Two pipes connecting the compressor in the engine room and the parts in the car. If the capillary tube is exposed, it can be proved that the temperature is very low. The belt tension of rotary compressor is also an important testing point. When you press hard with your fingers, you can bend about 1cm like other belts.

(2) Air conditioning is also used in winter.

The heart of an air conditioner is a compressor, which compresses cooling air into liquid. Only the mechanical parts supply lubricating oil here, so how should we actually maintain it? Adding oil to the cooling air of air conditioner can lubricate the internal circulation. Therefore, in order to protect the compressor, air conditioning should be used occasionally even in winter. In the warm days of winter, even if there is not much time, please turn on the air conditioner deliberately.

(3) The automatic air conditioner is not good.

The automatic air conditioner controlled at will makes people feel that the car must be more comfortable! Many people have experienced it. Although it is called automatic, it is not much different from manual air conditioning. If it is fully automatic, the speed of the blower will exceed the need, and it will be too cold in summer. Therefore, no one needs to stick to "full automation" when buying a car now.

(4) Turn on the air conditioner immediately after fogging.

Fogging in the window is the enemy of safe driving. Just bring two wet umbrellas on the bus, and you will find that the field of vision in front will immediately deteriorate. In this case, don't hesitate to turn on the air conditioner and set the temperature to low temperature. If there is an anti-freezing device at the air outlet, the fog will disappear immediately, and the fog at the rear window will disappear earlier than when using the dehumidification device, so please turn on the air conditioner immediately after fogging.

(2) headlights

(1) Detection and replacement sequence of bulbs

Headlights, direction indicator lights and brake lights, except halogen lamps, can't drive safely if they don't work normally. The glass part of ordinary electron tube (bulb) will turn black after use. Please replace it before wear. In case it breaks down during driving, you need to master the replacement of the light bulb so as to take immediate measures. Headlights are special, and vacuum tubes are plugged in and out from the back. Other light bulbs, like household light bulbs, are fixed by sockets. You can press the rotary button to remove it and install it. When replacing, use a bulb with the same shape and wattage as the old one. If you don't do this, you can't operate normally.

When replacing the headlight bulb, open the hood, pull out the contact part behind the lamp, and do not pull the lead wire. Take off the waterproof part, take off the spring claw that fixes the light bulb inside, and then take out the light bulb from the back. When replacing the light bulb, you must hold the terminal part for operation. If you touch the glass directly with your hands, the life of the bulb will be shortened. Please pay attention. Combined taillights, light bulbs on the inner side of reflector are juxtaposed. Find out the bulb that needs to be replaced and replace it with a bulb with the same wattage. Remove the headlights and bulbs of various lamps. Besides the different wattage and shape, we should also pay attention to replacement. Small bulbs without metal parts are usually used for side sign bulbs installed on car fenders. Please install carefully.

(2) If the light is too dim, you can use an efficient light bulb.

Headlights are too dim and dangerous. If they are bright, some accidents can be avoided. However, at present, most of the headlights of automobiles are made of resin, and they are afraid of heat, so they can't be equipped with hot bulbs, because heat will skew the headlights. At this time, the simple method is to use a brighter and more efficient light bulb than the same wattage. Just change the light bulb, and the operation is simple. People who think the headlights are dim recommend this kind of light bulb.

(3) Never forget to turn off the light.

The battery is dead. The reasons for battery consumption are different, and the losses brought to the battery are also different. The engine rotates too much, and the impact is light. The most troublesome thing is that small lights, indoor lights and other low-power lights will be out of power. In order not to shorten the battery life, pay attention to turn off the small light at any time.

(4) When the low beam lamp burns out, the adhesive tape can come in handy.

Headlights In most occasions, only low beam lamps are used. Originally, the high beam was the main light, but from the use frequency, the low beam became the main light. Due to frequent use, the probability of bulb burning out is very high. As for the headlights, if the low beam is burnt out, stick the upper third of the high beam with adhesive tape to cover the high beam, so that the high beam can be turned into a low beam. In case the low beam is burnt out, the adhesive tape will come in handy.

The above is some knowledge of automobile air conditioning and headlights. I hope that all car owners can help a little, and welcome everyone to communicate and interact.
