The cold winter affects our traditional fuel vehicles，It mainly starts difficulties，Cold activation idle jitter and cold car sound，This is the problem of the coldest winter in the cold winter，and not targeting a brand and model，It is all brands and models。

Let's take a look at why this situation is in depth，First of all questions，The most important three reasons for the difficulty of cold launch，Further understand the inherent knowledge of these three reasons，Finally, share how to effectively avoid or prevent these problems。

One of the main reasons for the difficulty of seabet iocold starting is the slow internal chemical reaction of the low -temperature battery，This leads to weakening the startup ability of the battery，Difficulty in starting a car，Another point is because the temperature decreases，The viscosity and density of the oil becomes larger，Weak liquidity，Rotating torque of the crankshaft increase，As a result, the cold start time of the car is extended to a certain extension。

The solution to these two problems is the following，Try to choose the place where the sun is like when parking，Check the life of the battery in advance，Keep the battery start in a good state，Avoid that the car cannot start normally due to poor startup status of the battery，At the same time in motor oil，We can try to choose a low -liquid low -viscosity oil，It is used to reduce the deformation of the oil fluidity caused by cooling caused by the difficulty of starting to start in the cold。

After talking about the battery and motor oil，There is a particularly important point. We cannot ignore，That is the fuel factors in the three elements of the car，According to studies, when the gasoline drops from 40 degrees Celsius to -10 degrees Celsius，The viscosity is increased by 75%，Given 5%density，So the atomization effect of gasoline at low temperature is poor，directly affects the cold start of the engine，and the smooth state of the engine cold start。

We have no way to change for the large external environment，But we can park the car to our own garage or the outdoor rising sun，It can help the car's cold start to a certain extent，and the stability of the cold start idle，Try to seabet ioadd higher gasoline to the regular gas station within the allowable range，Regularly add fuel additives，Ensure that the smoothness of the fuel pipeline and the performance of the fuel injection mouth fog，To ensure the stability of the performance of the cold start of the car and the stability of the cold start idle。

Vehicles in winter abnormalities，Because the temperature is too low, it will cause the object to harden，Including our car parts will harden，At present, the buffering parts between automotive parts are composed of rubber parts，and the rubber parts will harden in the low temperature state，Performance will be greatly reduced，So there will be abnormal noise when the cold car is started。

We still follow the usual style，After the failure of the failure，We give certain opinions and suggestions，In fact, when the temperature is lower in winter，There will really be many friends consult the car abnormal noise，There are many customers who go to the store to check the abnormal sound，But from the perspective of professional ethics，We will patiently explain the cause，The final suggestion is used normally，As far as the status quo is concerned, these parts do not need to be replaced without the service life.，and may not be better after replacement，The last suggestion for everyone，The coldest this few days of the chassis has abnormal noise and is within normal range，You can use it normally。
