The issue of hot cars has also been debated in the industry for a long time. Especially in the winter when it is cold, whether our car needs to be hot or not, how long is the heat Today, I have consulted senior repairmen and experts of industry associations, and I share the experts' suggestions with netizens. They say so, some people also think that the hot car is hot for more than ten minutes, the water temperature is expressed to a normal temperature before the start of the walking car, in fact, the hot car is a bit excessive, because the car in the case of idle speed for a long time low speed will produce more carbon deposits, which is not good for the engine.
There are also people, simply do not hot car fire on the go, this way especially when the weather is cold on the engine is very damaged, because in the winter when the oil becomes very viscous, the car starts after the supply of oil to the components is relatively slow, especially the bearings, cylinder walls, through the piston and other components wear more seriously, the car is usually cold start when the wear is more serious, hot car is the engine pulled to four or five thousand turns He is not as good as the wear of the cold start, so the engine noise will become more and more noisy for a long time. Even in the end there is a phenomenon of burning oil, so the car at the beginning, especially when it is cold, it still needs a hot car, whether it is a gasoline car or a diesel car, especially when it is cold, it must be hot, otherwise the life of the engine will be seriously affected. However, the hot car must master a degree, not a hot car, not a hot car, not too much hot car, how do we correctly grasp this degree is actually very simple.
Experts said such a simple method, this method for beginners to learn the car can also be quickly mastered, we observe the tachometer of this engine when we are playing the car, when we first started to hit the car, the speed of this speedometer is more than a thousand revolutions, that is to say, this speed is very high, we have to wait until this speed is reduced to 800 revolutions, that is to say, our car is on fire no matter how long as the speed drops to 8 million We can get off the car, but in the process of driving, we must also pay attention to a problem, It is at this time that the speed can not exceed 40 miles and can not increase the throttle, because at this time the water temperature has not yet come up, the engine is not a normal temperature, in the process of driving, we will watch our water temperature meter If the water temperature is expressed to 60 degrees, then we will have to drive at normal speed, that is, in the spring, summer and autumn, we also have to do these two points First of all, the tachometer is reduced to 800 rpm and then start walking. Second, look at our water temperature meter to reach 60 degrees during the driving process, we must be able to drive at a normal speed.
In fact, it is also very simple, I summed it up, that is, to look at the two tables, look at the speedometer when playing the car, when the engine reaches 800 rpm, you can get up the walking car, the speed can not exceed 40 miles after the second start, and then look at the normal speed when the water temperature is expressed to 60 degrees. Dear netizens, if you feel that this car knowledge is useless to you, please like, collect, forward, to bring convenience to more friends, thank you! The next issue will be more exciting!
