There are many reasons why it is difficult to start a vehicle, and low temperature is the common reason why it is difficult to strike a fire in winter.
In the low temperature environment, the chemical reaction of the battery will be slower than that in summer and autumn, and the ignition speed of the vehicle will also be affected. In addition, the quality of engine oil will also affect the starting of the vehicle. Because the viscosity of inferior gasoline will become higher in low temperature environment, it may block the nozzle, gasoline filter element and oil circuit, and produce more carbon deposits, which will lead to the engine speed not rising, and ignition difficulties are inevitable. So in order not to affect the normal use of vehicles, we must go to a regular gas station to refuel.
What other common reasons can cause difficulties in driving in winter?
1, the battery is low.
Batteries are not durable in winter, because most batteries are lead-acid batteries, and the discharge time of lead-acid batteries will be affected by temperature. The lower the temperature, the shorter the discharge time, which causes the power consumption of automobile batteries to be much larger in winter than in other seasons. This is like the same electric car. Under the same charging mode, the riding distance in winter is obviously shorter than that in summer.
Countermeasure: You can check the working condition of the battery regularly. For example, the voltage of a car battery is normally around 13 volts. If it drops below 1 1 volt, or even lower, it means that the battery has been damaged and needs to be replaced in time.
2, air intake system failure
The air filter in the air intake system is seriously blocked, which will lead to insufficient air intake and abnormal oil-gas mixing ratio of the vehicle, thus making it difficult to start the vehicle.
In addition, dirty throttle, intake valve or idle motor will also make it difficult to start the vehicle. Throttle can be said to be the throat of an automobile engine. Its upper part is the air filter and the lower part is the engine block. If the throttle is too dirty, it will produce more carbon deposits, which will not only make it difficult for the vehicle to ignite, but also affect the idle stability. In severe cases, the vehicle will stall when the throttle is turned off, which will affect the driving safety.
Countermeasures: It is suggested to clean the throttle once for 654.38+0.5 million kilometers; The gasoline filter should also be replaced regularly according to the situation. It is recommended to replace the gasoline filter every 40,000 kilometers. Fuel injectors should also be cleaned regularly.
3. The oil flow rate slows down.
When the temperature is low in winter, the viscosity of engine oil will increase with the decrease of temperature, which will lead to the slow flow speed of engine oil and the increase of engine resistance, which will make it difficult to start the car.
Solution: Check the oil mileage and shelf life regularly and replace it in time. Remember to use qualified engine oil, don't be greedy and cheap; Choosing the right engine oil grade, the northern car owners can choose the engine oil with better low temperature performance, such as 0W and 5W engine oil, and the southern 10W engine oil can be used.
In actual driving, you will always encounter different problems, but the solution is to prevent them in advance. For example, when winter comes, you can give your car a comprehensive maintenance and find and eliminate hidden dangers in time. Only in this way can you really reduce the trouble of driving.
