Automatic start and stop will not hurt the engine?

The car configuration is not high, depends on whether there is no dispensable, enjoyable configuration, such as this automatic start-stop system, previously seen in hundreds of thousands of joint venture vehicles can see the configuration, now we have 80,000 to block Money-made domestic cars have also been configured.

More and more people have experienced this configuration, but more and more people are worried that this automatic start-stop system will not harm the engine. Will it affect the life of the car and the battery life? Late maintenance costs are not high? and many more.

Let’s talk about a few more questions for you today.

First of all, many people are concerned that the automatic start-stop system increases the number of times the engine is started and shut down. Does this mean that the life of the engine will be reduced? Will not open for a few years, the rest of the car is not bad, the engine is scrapped?

In fact, the frequent start and stop of the engine, the damage to the engine itself is very small. As long as our engine has been properly maintained, the oil performance has not been attenuated, and there are not too many cold car starts. Repeated start and stop for the wear of the engine itself is minimal.

However, the start-up and shutdown of the starter and the entire starting circuit system reliability requirements will be relatively high. Now almost every manufacturer that starts and stops will do a special design for the durability and reliability of the starter before leaving the factory. It will calculate how many times the car will start and stop frequently within 100,000 kilometers, and make a match.

There are also people who worry that will it affect the life of the battery? If the car with start-stop function is using our ordinary lead-acid battery, it will really affect the battery life. It may take less than a year and the battery will be scrapped.

Therefore, vehicles with start-stop function are special start-stop batteries. This kind of battery is called AGM/EFB type battery. Everybody can look at the battery of their own car, have start and stop functions, and can see the two English letters. .

This special start-stop battery has a lifetime that is at least three times higher than that of a normal battery, and it is also more reliable than a normal battery at low temperatures. Therefore, there are professional start-stop batteries, we do not have to worry too much about the battery life.

In fact, there are some Mazda and Mercedes-Benz cars with start-stop technology that simply do not start with batteries. Instead, they start the engine directly with a direct-injection system.

However, there will be people who worry about saying that cars always stop and go this way. The number of engine starts is very large. Does it have a big impact on fuel consumption?

In fact, the original intention of the start-stop system design is to save fuel consumption and reduce pollution. The impact of the car's idle speed on fuel consumption is relatively large, and it also pollutes the environment. Therefore, when this kind of parking is waiting, the start-stop system automatically shuts off and stops the fuel injection.

As for the start will not increase fuel consumption? For the cold start, the fuel consumption will be slightly larger, but when we start and stop, we basically start under the hot car. Under the hot car start, there will not be too high fuel consumption.

Moreover, the automatic start-stop system does not directly shut down after you stop, otherwise it will increase several times the number of start and stop intangible, some car start and stop system is designed to step on the brakes for about 3 seconds After the flame is turned off, we can use this time difference to judge if we want to stop the car and turn off the engine.

Some start-stop systems will also detect if you are going uphill and downhill. If the detected slope is greater than 10°, the engine will not be turned off so that no flameout occurs on the ramp.

Therefore, since the start-stop system was selected, there is no need to worry too much about the life of the engine, the battery and the starter.
