Do you have a higher speed at startup and wait for the speed to fall before you go?

Our friends who have experienced driving know that cars will spin much faster during cold start. Especially in the winter in the north, some speeds can even reach about 1500 revolutions, which is much higher than the 700 revolutions at normal idle speed. Some car owners think that driving immediately at this time will definitely hurt the car, and other car owners believe that this is a normal phenomenon, and there is no need to heat the car in situ for a long time to increase fuel consumption. So when the car has a higher speed when it first starts, do the owners need to wait for the speed to fall back to normal before they can go?

The reason why the speed of the car will be much higher than usual when the car is cold starts is actually a protection mechanism when the car is designed, first of all, the high speed can allow our engine to enter the lubrication protection state as soon as possible, which is convenient for the engine to quickly heat up to a reasonable working temperature. At the same time, it is also to let the car's three-way catalytic converter enter a reasonable working rhythm as soon as possible. We all know that the three-way catalytic converter is used to improve the emission gas to protect the environment, and its best working temperature is 400 to 800 degrees. At low temperatures, it is not possible to make the three-way catalytic converter work, so the speed will be higher than usual.

Of course, now with the progress of the automobile production industry, our current cars no longer need to be in situ for a long time. When buying a car, we can pay attention to the instructions, and generally tell us to start the vehicle as soon as possible. But this does not alleviate the doubts of the riders, if the car starts cold, the car's lubrication system does not enter the state, we directly on the road will not increase the loss of the car?

Of course not, the manufacturers of the car will not be so irresponsible. In fact, the car will enter the lubrication protection much faster than we thought, basically within ten seconds after starting. At this time, the lubrication protection system is enough to support our car. But it is still necessary to say that it is better not to carry out violent driving after a cold start, so as not to cause too much burden on the engine of our car.

Of course, if there are still car owners who are not at ease, we can drive in the case of a relatively low cold start speed, because the cold start will enter a relatively normal idle period of about 1000 revolutions after maintaining a period of time at 1500 revolutions, at this time, whether it is lubrication protection or the heating of the engine and the three-way catalyst will reach a category that can be on the road, we do not have to waste a lot of fuel money in the hot car.

In the back, we still have to remind everyone that when the cold start speed in winter is high, although the starting vehicle will not cause harm to the car, it also needs our serious maintenance, violent driving, a foot of fast oil such behavior even at room temperature will bring damage to the car. Once the damage to the vehicle accumulates to a certain extent, it will have a great impact on our travel.
