When the temperature is low, it is difficult for the vehicle to start. After the car starts, the original floor heater is needed. It is not good to heat the car in situ. However, considering the weather in the northeast, it takes a long time to heat in situ because it is all MINUS 20 or 30 degrees. Then drive at a low speed. Hot car in situ will lead to excessive carbon deposition in the engine. Excessive carbon deposition in the engine increases fuel consumption and weakens power. So the local train will travel on the local train for 30 seconds. After 30 seconds, you can drive at a low speed. About five kilometers. Walk slowly. 2km, the engine can run normally when it is hot. Be prepared for freezing in winter.
Before talking about how to heat the car correctly, let's first understand the importance of heating the car. Why do we have to heat the car first on the road in cold winter? The root cause of hot car is that the temperature is too low, and the engine needs to reach the working temperature first. At the same time, restore oil lubrication to normal working condition. The importance of the engine is self-evident. If the lubrication is not good, the wear and tear of the car will increase, so we must heat the car first, which is also to protect our car.
According to the different situation of each car, the preheating time is slightly different. We need to remember that the process of hot car is a slow rising process, the temperature is also rising gradually, and all kinds of liquids are returning to normal work. So the hot car can't wait for a few minutes at idle speed. Need to idle and drive at a low speed when appropriate. It is not advisable to accelerate too early. Meanwhile, idling for a long time may not be a good thing. The service life of a car depends on the habits of the owner. Usually, car maintenance is very important. 30 seconds after startup to 1 min; Hot cars can't stay idle for a long time, because the condition of each car is different, which is mainly affected by the following factors.
