What is the automatic start stop function used for, and does it affect fuel consumption if it is alw

The function of automatic start and stop means that when we need it, the car can automatically turn off the engine, or start the engine by itself; I don't think it will affect fuel consumption if we keep it on, because we just started it, but we didn't drive it, so we didn't have fuel consumption.

It is a system in which the car automatically shuts off when the car is temporarily stopped, and the system restarts the engine when the car is approaching. Yes, according to some people's tests, if this function is not turned on, it can save about 5% of fuel.

If it starts and stops automatically, it is a function that we can use when we are close to the car, and this function is also more practical, so it will not affect fuel consumption if you keep driving.

Car owners will study all kinds of functions on the car after buying a car, but if you want to choose the most "useless" role, I believe that many car owners will choose to start the hail stop. In recent years, more and more vehicles are equipped with start-stop functions, but this is not wishful thinking on the part of car owners, but the manufacturer has installed it fully automatically when buying a car.

The biggest advantage of start-stop: the main reason for reducing fuel consumption is also to respond to the policy of environmental protection, at this stage, energy saving and consumption reduction has been the mainstream development trend of the world, so automobile manufacturers are also trying to do the emission norms, such as the familiar particle trap, such as the four-cylinder reduction to three-cylinder, such as the high-horsepower self-priming engine for a small displacement turbocharger, and such as the start-stop, all kinds of signs are in contact with the national environmental protection policy.

The most eye-catching advantage of starting and stopping is to reduce fuel consumption, which is also an objective fact. According to relevant research and testing, the vehicle containing the automatic start-stop function can save about 5% of gasoline and diesel than the vehicle without the automatic start-stop function, but after the 5% fuel saving, it is not equivalent to saving money, because it is equipped with an automatic running vehicle, although it is fuel-saving, but there is also a certain amount of energy, such as hurting the battery, and the cycle of operation has also caused a lot of pressure on the battery.

Disadvantages of start-stop: Constantly starting and stalling will lead to many adverse reactionsIn addition, starters, electric motors, and even car engines are inevitably affected. Let's talk about the battery again, equipped with an automatic start-stop function model battery, it is really an enhanced version of the general battery, automatic operation is to keep repeating the process of running and stopping the fire, and the whole process of repeating this day after day makes the general battery unbearable, although the start-stop battery is to upgrade the version number, but there is no too obvious advantages to talk about.

Ordinary batteries can generally be used for more than five years, but the service life of this upgraded version of the automatic start and stop battery has basically shrunk by half, and most of them are still around three years.

Because it is called the enhanced version, it is not cost-effective to take the price of the battery market of Qixing Lingjiao, and the common Japanese car battery ** is more cost-effective, ** is also about 800 yuan to 1000 yuan, and some high-end car batteries ** are generally about 2000-3000 yuan, in fact, it is a simple calculation to be able to get a lot of money to replace the battery, and it is impossible to save much money in comparison with the start and stop.

According to automotive experts, 80% of the wear and tear of the car engine comes from the moment the vehicle starts, and only 20% of the wear comes from the normal operation of the engine. Therefore, in the case of automatic start and stop without human control, it is actually very fuel-intensive, because the system will make frequent start and stop signals according to a series of factors such as road conditions. Brother pants cha.

The automatic start-stop function will not destroy the car, but will reduce the car's fuel consumption to a minimum.

I think the automatic start-stop function is indeed Yinyan is answering Brother Bo to destroy the car. Because many car owners are very unsuitable for the automatic start-stop function, this leads to the fact that the car often stalls because of the automatic start-stop in the process of driving.

Does the automatic start-stop function cost fuel The automatic start-stop function does not cost oil: 1. First of all, we must figure out under what conditions the automatic start-stop can be realized. The vehicle has just started, and the water temperature is not enough and the speed is low, it cannot be started.

Therefore, the realization of the automatic start-stop function must be in the case of a hot car. Unlike cold starts, the stalling and starting of hot cars, even if they are more frequent, will not cause wear and tear on the engine; After all, the engine temperature does not change much in a short period of time, and at the same time, the flow and wrapping of the oil will not change significantly; 2. When the battery power of the vehicle is not very sufficient, the automatic start and stop will not take effect. After all, after the engine is turned off, the generator does not work, and the work of the electronic systems in the car depends on the battery, such as air conditioning, radio, headlights, etc.

And if the start-stop is in effect for a long time, the engine will start again after the power consumption of the vehicle's electrical equipment increases, even if you do not step on the accelerator at this time; 3. Generally speaking, idling in the case of landing will consume 1 ml of fuel every 5 seconds, and a hot start will also consume 1 ml of fuel for the group tour cover. Therefore, as long as the parking time is more than 10 seconds, the advantages of automatic start and stop outweigh the disadvantages. @2019

According to the principle of automatic start and shutdown, even if the engine stops working, in fact, the oil system does not stop working, that is, the engine does not work, and the oil continues to flow inside the engine. If the engine is restarted, in fact, the engine will have better lubrication. The reason they say it's chicken ribs may be that a lot of people aren't very good at using it.

Either they don't know much about this feature, or they feel that when you start and stop automatically, the driving experience is poor, so when you get in the car, they turn it off. Many people will feel that frequent automatic starts and stops are harmful to the engine? Have you damaged the battery?

It can be said that the start-stop function is much more important to OEMs than to car owners, which is also the reason why the start-stop function has been fully promoted from top to bottom in recent years; In terms of rules, the start and stop function can make it easier for cars produced by OEMs to meet the standards, which is practically sufficient; The start-stop feature is certainly not new. Before answering the question, let's first understand the feature of automatic stop configuration. In short, the auto-stop function is a system that automatically controls the stop and start of the engine.

In the event of a short-term shutdown, the engine may automatically go to "sleep", and with regard to engine start and shutdown technology, it is good from a development point of view. In particular, by installing a reinforced engine with an idle start and stop function on a conventional engine, the engine will shut down completely when the vehicle meets the start-stop conditions. When it is time to restart and restart, the engine start and shutdown system will quickly respond to the driver's commands, and the automatic start and shutdown of the engine will automatically stop the engine when the vehicle is temporarily stopped, such as when waiting for a red light, a system that automatically restarts the engine when it has to move forward.

It has the function of starting and stopping conventional engines by installing an enhanced engine, and in order to cope with severe vehicle exhaust emissions, Toyota has tried to optimize the thermal efficiency of the Interna L internal combustion engine and continuously improve its hybrid system. For other brands that are not as strong as Toyota and other FAW companies, even if there is no powerful gasoline-electric hybrid system, from the perspective of big data, the current car has evolved from some models with start and stop functions to general-purpose models with this function. If this is a chicken rib feature, are all the car companies rushing to install it?

In fact, this function is more fuel-intensive, because it will cause some damage to the fuel tank, and there will be a lot of problems, and a lot of situations will occur when driving.

There are both, and this function is actually advantageous and disadvantageous, so when this function is designed, it is not particularly reasonable.

This automatic start-stop technology is designed to keep the car in a dormant state for a short time, and the main purpose is to reduce the emission of exhaust gases, the moment the engine stops running, it does save fuel consumption, but you must know that when you start again, the fuel consumption required by the engine at this time is 1 minute quota idle fuel consumption. So if you don't have more than 1 minute to wait for the traffic light, there is almost no fuel saving with this automatic start-stop function. Not obvious.

Why do you have such an idea, because many drivers think that the car is frequently turned off and started in the domestic production, which will lead to wear and tear of the engine, and ultimately affect the engine function. This must be admitted, frequent start-off has an impact on the engine, but this is generally to establish self-love The engine is in a state of cold start, and most of the use of this function is that the engine is working at room temperature, so the loss is negligible and the impact is not great. However, because frequent start-off will also produce carbon deposits, which will have an impact on the life of the car for a long time.

Automatic start and stop generally as long as the car starts, then the automatic start and stop will be in a normal working state, when you need to stop at a traffic light or other reasons, you only need to step on the brakes, then the engine will automatically turn off after two seconds, it can be said that the start and stop function is far more important to the main engine factory than to the owner, so this is also the reason why the start and stop function is fully popularized from high level to low level in recent years; The start-stop function is in terms of rules, which can make it easier for the car produced by the OEM to meet the standard, which is actually enough; The automatic start-stop function is a system that can automatically control the engine to stop and ignition, and the engine can automatically enter the "hibernation" state in the case of a short stop.

It will interfere with the operation of other equipment, especially the use of air conditioning, and many models will cause the compressor to fail to operate normally after the start-stop function intervenes, so only air supply is not cooled, which seriously affects the comfort. It is by implanting a reinforced motor with an idle start-stop function in the traditional engine, so that the engine of the car is completely extinguished and does not work when the idle stop condition is met. On the one hand, this start-stop is to save fuel, on the other hand, it is also to let the engine take a short break, which is computer-controlled, and it is no longer completely mechanically stopped and turned off, but turned on when walking.

When you are waiting for a red light, the foot presses on the brake for a second or two to trigger the automatic start-stop work, at this time the engine will enter the state of shutdown and sleep from idle, when you release the brake pedal or turn the steering wheel, the engine can start on its own. The engine automatically stalls and does not idle, and when the foot leaves the brake pedal, the engine automatically ignitesIt is conducive to the reduction of fuel consumption, There is an automatic start and stop device of the car, many car owners have been entangled in whether to open or close, is a more controversial issue, as I know, many car owners are willing to close the device for a long time, my personal suggestion is not to agree with the long-term shutdown of the use, automatic start and stop technology is not as bad as the first generation of experience, when opening is basically not so shaky, the sound is not so loud, there is still its application scenario.

A large number of tests have proved that after turning on the automatic start and stop, it can save about 8%-15% of fuel on the road. However, some car owners have raised questions: if the road conditions are too bad, the start and stop time is very short and frequent, will the fuel consumed by the car start more than not turning off the engine?

In fact, after the automatic start-stop takes effect, the engine is still in a state of "high temperature" because it has just stopped working, so when it is restarted, the resistance is relatively small. Studies have shown that in such a state, the fuel consumption of the engine starting is only equivalent to the fuel consumption of seconds in the idle state, so in theory, stopping for more than 1 second can save fuel.

Personally, I think this feature is relatively ruining the car, because I think it will obviously put the car in a more awkward position.

This operation is very fuel-efficient, but it does not destroy the car, because although the automatic start and stop is fuel-efficient, the frequent start of the car is very harmful to the battery.

Many car owners believe that frequent stalling during driving will cause excessive wear and tear on the engine. It is true that frequent start-stops can cause damage to the engine, but we all overlook the important point that most of the wear and tear of the engine occurs during cold starts. More than 80% of engine wear occurs at the moment of cold start, and the remaining 20% or so occurs at normal idling.

<> "Is the function of automatic start and stop save fuel or destroy the car?"

What is the automatic start-stop function, as the name suggests, this function can react automatically when the car is temporarily stopped, and when the car is about to move forward, it can automatically restart the engine quickly, which is a set of intelligent systems in the car. The automatic start-stop function is generally only available on high-spec cars, but unlike the panoramic sunroof, not all owners will like this function.

This feature was originally designed to help the car save fuel, but now many people are arguing that the car stops for a short time, does not save much gas, and not only that, but also doubts that such frequent repeated stalling and starting the engine can cause damage to the interior of the car. In fact, whether this doubt is correct or not, I will explain it today.

The first large-scale use of the automatic start-stop function is due to the European fuel cost**, although many countries in Europe have strong economic strength, but the high cost of fuel makes them have to introduce automatic start-stop technology, even if the process of starting every time the car is turned off is very short, but it can still save about 10% of gasoline.

This function may not be very conspicuous in the usual traffic lights and other traffic lights, but when the Spring Festival is approaching, the owners must have a deep understanding of the traffic jam phenomenon, in the rush hour, stay on the road for half an hour, at this time the automatic start and stop of the line of information rolling can help the owner save a lot of fuel.

As for the question of whether the automatic start-stop function will hurt the car, there is no need to argue, the answer is that the damage to the car is minimal. It is precisely because most of the temporary shutdown time is very short, the oil responsible for lubricating the engine has not had time to flow away, the engine will start again, the start at this time is called hot start, there is no big problem of wear, the engine is wear and tear damage is the cold start, that is, the start before going out every day.

The main reason why we don't like this function is that sometimes when you shouldn't turn off the engine and stop-and-go, the car will shake non-stop, the development trend of this function should be universal, taking into account the amount of exhaust gas emitted and the world's oil reserves, engineers will gradually improve the automatic start-stop function, and further improve the existing problems.
