The biggest difference between people is cognitive blockchain
The main reason why it is difficult to start the engine cold is that the temperature of the engine is too low. As long as the engine is kept warm and the chilling wind does not blow directly into the engine compartment, it can avoid being unable to hit the car. Therefore, when parking in winter, you should pay attention to the direction of the front of the car. It's better to make the front of the car face the building and use the building to prevent the engine from being too cold e to the cold wind. When parking at night, you can point the front of the car to the sunrise direction, so that the first ray of sunlight in the morning can shine on the front of the car to help the engine heat up, so that it is much easier to drive. Usually also regularly to the designated service station to check, adjust, shift engine flameout
extended information:
attention should be paid to starting in winter:
after starting the engine, turn on the lights, radio and other electrical equipment. Before parking, turn off these power consuming appliances before turning off the engine. Because at night after the vehicle flameout, the battery is still in a state of discharge. At this time, static discharge current is generated, which is very small, generally below 0.1 A, and belongs to normal discharge
in winter, the vehicle should arrive at the maintenance station early to detect this parameter. For some vehicles that have been driving for many years, the quiescent discharge current may reach 1 A or even several a, which may easily lead to battery loss and may not be able to start the next day. Generally speaking, below 0.5 A is within the acceptable normal range< br />
in order for the engine to run normally, several conditions must be met at the same time: fuel, air and starting energy
the most important thing is the starting energy. The reason is that the spark plug should have energy to ignite, and the starter should also have energy to run and drive the engine to do work, and their energy is electricity
so we often encounter the fault that the car can't ignite normally. In most cases, it is caused by the lack of electricity, that is, the battery loses power
if the battery is not used for a long time, it will discharge itself. If it is too long, the battery will be out of power. In addition, after the engine stops working, that is to say, after flameout, it is necessary to avoid using the electrical appliances in the car. Without the power supply of the engine, long-term use of electrical appliances, such as car audio facilities, or car headlights, will consume the power inside the battery< Second, the ignition system has a fault
e to the low air temperature in the cylinder, the fuel atomization in the cylinder is not good, if there is insufficient ignition energy, it is easy to cause the phenomenon of cylinder flooding, that is, too much fuel accumulates in the cylinder, exceeding the ignition limit concentration and unable to land
PS: the ignition limit concentration is a range, but it's not a value. It can only be ignited within this range, even if it's too high or too low
in case of this problem, you can check whether there is oil stain between the spark plug electrodes. If it is cleaned, it will catch fire after it is installed. The thorough way is to check the ignition system and eliminate the causes of low ignition energy, such as spark plug electrode gap, ignition coil energy, high voltage wire state, etc< Third, the exhaust pipe freezes in winter, when the weather is cold and the temperature is low
for those car owners who are close to their home, their car use frequency is relatively low. The water vapor generated by engine combustion freezes on some parts of the exhaust pipe, and the heat of short distance driving is not enough to melt the ice. After a night, more ice forms, and the cycle time is long, It will affect the starting and exhaust of the vehicle
so you can't save the car. Don't put it in the corner all the time to eat ashes. In this way, the car condition will be worse and worse< In addition, water or poor antifreeze may be added in winter, which may cause the waterways to freeze or even the engine to crack, and the automobile water pump can not work
