What is the difficulty in starting a car in winter?

There may be several reasons why it is difficult to start a car in winter. In winter, batteries have the most direct impact on urban family cars. At low temperature, the power consumption of cars will be significantly higher than other seasons, and the capacity of batteries will also decrease due to low temperature environment. If winter comes, go to the franchise store to replenish the battery or replace it with a new one in time, this situation can be effectively avoided. The oil flow is blocked, especially in the northern cities where the temperature is particularly low. In winter, the viscosity of engine oil will increase, and the flow of engine oil will become more and more difficult, thus increasing the resistance of the engine and making it difficult to start the car in winter. In this case, the emergency solution is to put the car in a warm environment and start it normally after a period of time. But if you want to solve it completely, you'd better go to a franchise store to do a professional winter maintenance and change the appropriate oil according to local conditions. Exhaust pipe icing, electronic throttle carbon jam and other exhaust pipe icing situations mainly occur in those car owners who are close to home and work. Their cars are used less frequently, and the steam after engine combustion will freeze in some parts of the exhaust pipe, but short-distance driving is not enough to melt ice, and more ice will be formed after one night. Over time, it will have an impact on vehicle start-up and exhaust gas. Of course, the solution is actually very simple. Run high-speed every weekend in winter, and discharge the accumulated water in the exhaust pipe in time with strong exhaust force. In addition, the electronic throttle of the automobile is a device to control the air flowing into the cylinder and generate negative pressure. Due to the incomplete combustion of gasoline in the combustion chamber, tiny carbon particles are produced, thus forming the so-called "carbon deposit". As the temperature of the whole engine drops after the engine is turned off, these dirty things will be more stubbornly fixed on the throttle, making the flexibility of the throttle worse, so the throttle will get stuck when it turns. With the decrease of temperature in winter, it is suggested that the owner should clean the electronic throttle regularly to completely eliminate the unstable idle speed and the increase of fuel consumption caused by carbon deposition in the throttle.
