In our lives, intelligence is also common. For example, our mobile phones have long been upgraded from elderly machines to their current intelligent mobile phones. Cars, for example, but so far almost all cars are manually transmitted. But now with the development of science and technology. Almost all cars on the market have been replaced by automatic gears. Even if you don't have a car, your friends who have obtained a driver's license will know. When we register for the class exam, it is divided into automatics and manuals. The skills learned in the two classes are different, and the models of operation are also different. So, what is the difference between a manual car and an automatic car? Automatic lockdown occupies a lot of markets, where are its advantages?
In fact, the automatic transmission car is not as good as everyone thinks, and there are certain shortcomings. The automatic transmission can automatically identify the speed at that time through its intelligent system, so as to better change the gear, without the need for the driver to switch, as long as the brakes are controlled. However, since there are many kinds of automatic transmission, it has become one of the disadvantages. Because the price of each product is different, the performance is also different. What's more, due to the relatively short life of automatic transmissions, the taxis we see on the street are almost always manual. However, whether it is a manual or an automatic gear, you need to prepare a hot car before driving. Especially in the winter in the north, the temperature in the north and south is very different. Temperatures in the south are also as low as around zero in winter, but the lowest temperatures in the north can reach minus 30 degrees. So, in such a cold situation, the car needs to be heated. There are also cars with poor performance. It can't be launched at all.
In winter, there are indeed many people who have the habit of hot cars. People with no driving experience believe that the hot car is actually because the temperature inside the car is higher, in fact, the car has been precipitated at night, and the oil has accumulated at the bottom. If it is not hot, the fluidity of the liquid will slow down, so the engine is generally started before running, and the oil is delivered to various locations where oil lubrication is required. A lot of beginner drivers of automatic cars start asking questions. When the automatic car is hot in winter, is it better to sit in p gear or n gear? The old driver gives the standard answer, quick to understand.
After the driver gets on the car, the first step is to carefully check the function of the car to ensure that there are no errors. Use the hind legs to step on the brakes to start igniting. Generally, in the cold winter, you have to set fire to the car many times, but do not drive immediately after starting. The oil also settles at the bottom and needs to be penetrated to various locations. In that case, you need to heat the car on the spot for 1 minute, or the needle of the tachometer drops below 1000. Drivers for many years said that when heating the car, they need to hang up the p-gear on the spot. Otherwise, it will cause engine damage and easily pull the cylinder.
So, why hang p gear instead of n gear? In fact, in a hot car, as long as you don't hang up the forward and backward gears, the vehicle is almost undamaged. The difference between p-gear and n-gear is that the safety of n-gear is relatively low. If you hang up in n gear and accidentally pull up the hand brake, the possibility of squeezing through will become greater. Especially in the location with a ramp, it is easy to accidentally cause traffic accidents. This is not common, but there is a history. Therefore, for the safety of ourselves and pedestrians, we had better be cautious. Be careful not to touch the brakes and shift gears on the hot car, and do other operations after the hot car is over. Please also take advantage of the hot car time. Can't be too short. Too long is not enough.
Just a minute. Delivering oil to the location where the engine needs to be lubricated is the best method for automotive use. Some driver friends felt that one minute was not enough and wanted to heat up a little more. The time of the hot car reached three or five minutes, or even more than ten minutes. In fact, this is a very undesirable behavior, if the car is in a low-speed state for a long time, the gasoline combustion will not be complete. Over time, carbon will accumulate, but even if this happens, don't worry. In the case of a long service life of the car, the occasional use of fuel treasure can eliminate the long-term carbon deposit to a certain extent.
Conclusion, after turning off the p when the hot car is 1 minute, you can enter the driving state, but please be careful. The oil is delivered well, but the water temperature of the engine has not yet risen. Therefore, in the beginning, do not drive at high speed, just maintain a speed of 40 or 50 kilometers per hour. When the water temperature reaches more than 100 degrees, it can be used freely. A lot of people can drive but don't understand how cars work. The degree of loss to the car will be very large. Proper use of car driving can extend the life of the car. This is also the opening method of the throttling source.
