Pay attention to the maintenance of the starter and prevent the battery from “flame-out” in summer[汽车维修知识]

According to experience, winter is a frequent period of vehicle battery failure. Due to the low temperature, the battery discharge is not active enough, and the oil becomes viscous, the vehicle often cannot catch fire, but the owners may not know it, and the high temperature weather is also difficult for the battery to adapt.
According to Wuhan BiaodicarLin Hui, general manager of the Service Co., Ltd., introduced that after the summer, the circuits and motors on the vehicles have become the hardest hit areas for maintenance. Within a month, the store received 11 battery repair accidents, three or four times more than usual.

When turning on the air conditioner, try to turn on the speakers as little as possible
"After the hot weather, the number of battery replacements and maintenance has increased three or four times than usual." Lin Hui said that vehicles in the city have been driving at low speeds for a long time, and the owners often turn on many power-consuming functions at the same time, which makes the batteries fall into A severe power loss state makes it difficult for the vehicle to start. At the same time, the long-term power loss of the battery will accelerate the aging, and the final service life will be greatly shortened.
Lin Hui reminded that the car should mainly pay attention to "lightening" the vehicle: first, when the air conditioner has to be turned on while driving, try to minimize the use of other power-consuming functions, such as audio, cigarette lighter, etc.; second, minimize the continuous operation of the vehicle If the driving time is too long, stop and take a break to let your car take a breath.
Always pay attention to maintenancestarter
"In hot weather, the starter is also a component that is prone to problems." Lin Hui said that when the temperature rises, coupled with the heat emitted by the engine when it is working, it is easy to cause the starter's insulation to decrease, turning weak, or even not working.
It is understood that the starter is leaning against the engine, passingAccumulatorAfter the power is supplied, the engine is driven to perform normal work. It is mainly surrounded by insulated copper wires, and the degree of insulation will directly affect whether the engine can start normally.
Lin Hui introduced that the common faults of the starter at high temperature include loose lead wires, short-circuit or blown windings, and excessive wear. He reminded the car owner that after such a failure, it is best to go to a professional repair shop to replace the corresponding copper sleeve and re-wind the cable. In addition, car owners should strictly follow the procedures during use, especially old cars, should be maintained, and problems should be repaired in time.
Pay attention to the line layout when repairing the car
With the increase in high technology of automobiles, the lines on the body are very dense. Lin Hui said that the wiring on the vehicle should be rationally arranged according to the structure of the vehicle to avoid melting at high temperatures, short circuits after friction, and fire.
E.gsensorHarness awayexhaust pipeVery close, if it is not reasonably arranged and fixed, it is very easy to cause the line to stick to the exhaust pipe with a high temperature of thousands of degrees, which will cause the line to melt. Once it encounters oil stains, there is a possibility of fire. In addition, the wiring in the hood is intricate and complicated, and the vehicle will experience varying degrees of failure if the owner does not pay attention.
Lin Hui suggested that when the vehicle is repaired, it is best to go to a designated brand or a large professional shop for repairs, so as not to avoid unprofessional technicians neglecting the reasonable layout of the line.
The mechanical part cannot be ignored
"Vehicles working at abnormal temperatures can easily cause increased wear and tear on mechanical parts." Lin Hui said that under extremely high and low temperatures, the wear level of vehicles has increased than usual.
According to reports, at high temperatures, the oil film of the mechanical and mechanical connection parts is easily broken, and the two lose the lubrication of the oil film, which will increase the friction of the mechanical part invisibly, and it will deform after high temperature. The temperature control of the mechanical part is now mainly controlled by the computer-if it is overheated, the computer will automatically cool down; if it is too cold, it will increase the temperature. Therefore, try to ensure that the vehicle works at an appropriate temperature.
Lin Hui reminded that if you want to ensure that the mechanical parts are not damaged, you must first ensure that the normal operation of the mechanical working parts is affected.
