Introduction | Yen value and work efficiently without it
When it comes to the grille, I am sure you are not familiar with. It is one of the most important elements of the front face, greatly provide support for family-oriented design. The functionality, it can be ventilated to the intake tanks, engine, air conditioning, and to prevent damage spatters in the front compartment with the inner member.
going to talk about today’s active grille also into one kind of grille, but the smarter . The reason to take this particular auto parts out of chat, because the car is still gather around the monarch found a lot of people do not understand it, but in fact it are promising in the past, present and future, so it is necessary to make a good presentation.
First, the active grille role
If you have read touring car, you will find a lot of racing network are being foreclosed, do so precisely in order to keep the engine in the shortest time to reach optimum operating temperature, and thus play a better performance.
Why do you say? We know that cold start, this is not a high temperature of the cold air outside the tank had to be cool again, so the water temperature is very slow, the time required to enter the engine will be longer in top working condition.
is not only affected the car, the engine can be said to affect the operation of the cryogenic great extent, many models therefore reducing the effects of the warm air in the winter, and fuel efficiency will deteriorate. If you live on the memory of the 1990s there will certainly remember the many buses will put on the front of a quilt in the winter. Bus stop and go mode this will burn more oil, so it is critical to maintain optimal operating temperature.
compared to the outlet of such blocking mode “fool” the active grille to be much more intelligent.
on the work characteristic, the active grille system through the relevant sensor information, based on temperature information of the engine, the electronic unit is automatically controlled by the opening bladeKai point of view, so as to achieve the effect of rapid hot car, the engine in the shortest time into the best working condition.
In fact, very active grille already appeared, impressive is the 2012 listing of the new Focus, it was the whole system comes standard with this device. And the biggest feature in that it has up to 15 different opening angles, as is more finely control the amount of air entering the engine compartment.
Second, why in the future or will it become the standard?
If it is the general direction, the active grille previously often seen in the United States Department of the car. For example, the above talk to Fox, or Cadillac, Buick, Chevrolet and other models are also equipped, new large SUV is expected to be another banner Ke Angke November 20, 2019 officially listed also comes standard with active air intake grid gate.
▲ BMW of course also like to configure it, like the BMW 5 Series is the whole system comes standard, but with the price of their own brothers X3 not even an option at all, so many people Tucao.
why this is so, and there is a certain relationship between the use of the environment, and more highways in North America, strong wind resistance fuel consumption as the main culprit. Active grille off an appropriate amount, thereby reducing the drag coefficient, and thus improve fuel economy and vehicle stability.
For example, Cadillac ATS-L, when the vehicle speed is higher than 60km / h, the onboard computer will automatically monitor the temperature of the engine, while ensuring no additional air cooling, active closed grille will play effect.
to the next this, we can conclude that the active grille of advantages:
▎ help cold start, the engine faster to pull most good working environment;
▎ reduce the drag coefficient when driving at high speed, to save fuel.
On these two points, in the era of penny-pinching on fuel consumption has been attractive enough can be said to be active grille on the basis of the future can be heavily promoted.
However, there is basis certainly is not enough, after all, to solve the above problems we can use other means, such as selecting select low-viscosity oil (winter), a more streamlined body design, it can all be alleviated.
Why car poly Jun predict its promising future, and may even become the standard for two reasons.
▎ Hyundai popular mouth design, and design trends is not only the largest bigger. Mouth grille will mean a greater impact on the engine and wind resistance will be more obvious. If this time configuration motivated grille, would be better.
▎ active grille gradually dropping the trend, such as the lucky star, Chery Tiggo 7, 730 Po Chun Po Chun 510 and other models have a configuration in high accompanied. And because of work, and now a lot of car poly Jun found it increasingly concerned about the new models in the development stage, I believe the future will usher in a wave of small eruptions.
Third, electric cars need this configuration?
Some people may ask, electric car without an engine, you also need grille it? Since no intake grille, active grille did not even useful here.
This is indeed a good question. Electric cars can not really use the grille, because there is no internal combustion engine, the electric car, no grille to heat, and the cancellation grille can also reduce wind resistance.
how to do that cool? Of course, there is also a solution. Forced air cooling system, such as battery power, is the use of a blower, the air conditioning refrigeration system through the evaporator into a cold air, over the same set of special cells to blow pipe, toBattery cooling.
However, in fact, provides for better air, such systems is best to have a relatively large wind sources, so although grille smaller (or disappearance), but the lower part of the skirt will still be hollow.
Further in addition, another under the action of the skirt portion is hollow to cool the motor. So the whole, the future is likely grille into another look, use the lower part of the skirt.
A very typical geometry like Geely, at first glance, is the faceless A geometric modeling, but in fact, strictly speaking, it’s under the skirt is hollow, and the grille is proactive.
Allegedly, the reason is because you want so designed grille can match different speed different opening and closing angle, effectively reduce the drag coefficient, but can flow downward to the chassis of the battery pack, cooling. Our thoughts and coincides with the above analysis.
Of course, in addition to the above explanation, the reality is more, many hybrid or pure electric vehicle from a conventional internal combustion engine platform, in such architectures, the battery and the motor cooling passage and conventional diesel-type high similarity, and therefore the intake grill is not small.
car poly Summary
its own human civilization, we have been dealing with the wind and fire. Make good use of the wind, rather than 100 percentage denial of it, this is the wisdom of the wisest strategy. Active grille is this control “style” products, will inevitably promising in the future.
For the emotional, the king does not want a car poly signature elements of the front face, grille demise of this, because it is closely related to our aesthetic. So finally, to feel under various classic grille shape it, do not say you do not love.
