One question has always been controversial. Is it necessary to warm up the car when it starts in the morning? Everyone has a lot of opinions on the issue of starting hot or not hot cars. Some people say that there is no need to warm the car, and some people insist that it must be good for the engine. Is hot car necessary in daily life? Today I will tell you in detail!
Due to the low temperature in winter, human immunity will be reduced accordingly, and it is extremely easy to get sick. The same is true of cars, which are prone to various failures in winter, which is called “winter illness”. These problems not only upset people, but also pose a greater threat to driving safety. Now, let ’s talk about the six “winter illnesses” common in cars.
How many kilometers can a car run? 4.8 million kilometers. A Volvo P1800 sedan in the United States has ran nearly 4.8 million kilometers in 47 years since 1966, setting a Guinness World Record for the longest mileage of cars in the world. Of course, all this can not be separated from the car owner’s meticulous care. However, this car has been repaired twice, but the engine has not been replaced.
Can all cars run for so long? the answer is negative. Factors such as car quality, car environment and maintenance will affect the life of a car. The Volvo car, which runs 4.8 million kilometers, is obviously just an example.
So the question is, how long can a family car be driven with proper maintenance, among other factors?
Everyone who drives a manual transmission should know that the engine speed will drop when the gear is turned on. For example, when you are in the third gear at two thousand revolutions, if you change to the fourth gear, the speed may fall back to 1,500 revolutions. But if it is downshifting, the speed will increase.
When servicing a vehicle, there is usually a service called throttle cleaning. But what the hell is the throttle? Why clean it? Why is it dirty?
This is the throttle valve. The throttle valve controls the air intake of the engine. The current throttle valves are all electronic, and the cable is cancelled. Therefore, the stable idle speed is also controlled by the throttle valve. If it becomes dirty, the idle speed will be unstable and serious. Cold start is difficult, and the fault light will be on. Generally speaking, cleaning the throttle valve is simple, but there are also unreasonable designs that are more difficult to wash!
Many car owners have encountered driving at night. Although driving at night is dangerous, we often drive at night because of our work or personal reasons. However, there are many precautions for driving at night, which we must pay attention to, otherwise it will cause tragedy.
What if the car doesn’t meet for half a month?
The car hasn’t been driven for half a month, nothing has happened! At most, there is a thick layer of dust on the car, just wash the car. Everyone may wonder whether the battery of the vehicle will run out, whether the engine oil and the entire vehicle oil will deteriorate or solidify. First of all, the battery will not run out in a short time, and the entire vehicle oil will not solidify. If you have n’t driven for six months or more, and the car is exposed outdoors, the oil may be deteriorated after the hot and cold alternation. If it is within 1 month, there is basically no problem.
Many people on the Internet say that the oil will deteriorate when the car is left for a long time. This is too far-fetched. Generally, the shelf life of motor oil is about one year. Although it may be changed after adding it to the car and mixed with oil sludge, etc. Resistant for half a month. It ’s just that after a long period of time, most of the engine oil in the engine has flowed back to the oil pan. When you start the car, do n’t step on the throttle. Wait a few tens of seconds for the oil pump to pump the oil out.
With the increase of cars, traffic accidents have become more and more frequent, and the most frequent accidents should be counted as rear-end collisions, especially when some road conditions or weather conditions are more complicated, large-scale rear-end collision accidents often occur. The extent can be seen, so how to rear-end accidents are so dangerous and how to avoid them. Don’t worry, the editor has a few suggestions.
With more and more car buyers, everyone is starting to pay attention to car-related issues. Take car washing, for example, many people wash their cars only when they find that the surface of the car is dirty. Moreover, washing the car on the substrate is to wash the outside of the car once, and the inside of the car is ignored. But in fact, our car is sometimes dirtier than the outside, and we usually find it harder, so we often ignore these details when we wash the car. Even if we go to a car wash shop, you don’t stress the car washers, they won’t wash you. Some cars have not been washed in these places. Let’s take a closer look at the dirty places on these cars.
