Winter is less than halfway through, the cold wave comes wave after wave, the northern region has cooled down sharply, wear less and stand outdoors for a while, and if you are not careful, you will freeze into an "ice sculpture".
Having a car is different! Walk with friends and family, travel by car, no matter how cold it is outside, the car is warm and melting. But sometimes, everyone will encounter this situation, just about to leave, but found that the car can not start...
There are many reasons why vehicles are difficult to start, and low temperatures are a common cause of difficulty in lighting fires in winter. In the low temperature environment, the chemical reaction of the battery will be slower than in summer and autumn, and the ignition speed of the vehicle will be affected.
In addition, the quality of the oil will also affect the start-up of the vehicle. Because the viscosity of inferior gasoline will become higher in the low temperature environment, it may appear to block the fuel injector, gasoline filter and oil circuit, etc., resulting in more carbon deposits, which will cause the engine speed to go up, and it is inevitable that the ignition will be difficult. Therefore, in order not to affect the normal use of the vehicle, everyone must go to the regular gas station to refuel.
What are the other common reasons that make it difficult for your car to start in winter? Let's take a look at it together
1
The battery is low
The battery is not very durable in the winter, this is because the battery is mostly lead-acid battery, and the discharge time of the lead-acid battery will be affected by temperature, and the lower the temperature, the lower the discharge time, the shorter the discharge time, which causes the car battery to consume much more power in winter than in other seasons.
It's like the same electric car, and with the same charging method, the riding distance in winter is obviously shorter than in summer.
Coping method: you can regularly check the working condition of the battery, such as the car battery voltage is normal at about 13 volts, if it falls below 11 volts or even lower, it means that the battery has been damaged, and it must be replaced in time.
02
Air intake system failure
Serious blockage of the air filter in the intake system will lead to insufficient intake air, causing an abnormal oil-gas mixing ratio of the car, resulting in difficulty in starting the vehicle.
In addition, too dirty throttle, intake valve or idle motor can also cause difficulties in starting the vehicle. Throttle can be said to be the throat of the car engine, its upper part is the air filter, the lower part is the engine block, if the throttle is too dirty, it will produce more carbon deposits, not only will cause the vehicle to ignite difficulties, but also affect the idle stability, serious when the throttle will lead to vehicle shutdown, affecting driving safety.
How to deal with it: It is recommended to clean the throttle every 15,000 kilometers or so; the gasoline filter should also be replaced regularly according to the situation, and it is recommended to replace the gasoline filter every 40,000 kilometers; the fuel injector should also be cleaned regularly.
03
The oil flow rate is slowed down
In winter, the temperature is low, and the viscosity of the oil will increase with the decrease in temperature, resulting in slower oil flow speed and increased engine resistance, resulting in difficulties in starting the car.
Coping method: regularly check the oil mileage, shelf life, timely replacement, remember to use qualified oil, do not covet cheap; choose the right oil label, the owner of the north can choose a low temperature performance of the oil, such as 0W, 5W oil, the south 10W can be.
In actual driving, everyone will always encounter different problems, but the best way to solve the problem is to prevent it in advance. For example, when winter comes, you can do a comprehensive maintenance of your car, find and eliminate hidden dangers in time, only in this way can you really reduce the troubles of driving.
