More and more vehicles are now equipped
Automatic start-stop function
Convenient for our car life
However, some car owners and friends are worried:
The engine wears out the most when the vehicle starts,
So frequent automatic start and stop,
Will it hurt the engine?
On the life of the car and the life of the battery
Will it have an impact?
Let's talk about this topic
Does automatic start-stop hurt the engine?
In fact
Frequent start-and-stop of the engine,
The damage to the engine itself is very small.
In any design or configuration, the engine life is the first, and the manufacturer's design engineers will not sacrifice the engine life in order to save fuel, which will not be worth the loss.
In the hot start state, the coordination gap between the engine parts and the oil lubrication have entered the ideal working state, and the interval between starting and closing is very short, most of the oil is still in the oil duct, the wear of the engine at this moment is very small, and the most critical factor affecting the engine becomes the lubrication performance of the oil.
As long as our engine does normal maintenance, using high-quality oil, there is not too much cold car start, and the repeated start and stop is minimal for the wear and tear consumption of the engine itself.
In addition, the reliability requirements of start-stop for the starter and the entire start-up circuit system will be relatively high. Nowadays, almost every manufacturer who does start and stop will make a special design for the durability and reliability of the starter before leaving the factory, and will calculate how many times the vehicle will start and stop frequently within 100,000 kilometers, so as to match.
Will automatic start-stop affect battery life?
And some people will worry,
Increased number of starter jobs,
The number of large-current discharges in the battery increases,
Will it have an impact on the life of the battery?
In fact, if the vehicle with the start-stop function uses our ordinary lead-acid battery, it will indeed affect the battery life, and it may take less than a year for the battery to be scrapped.
However, the cars with the start-stop function are all special start-stop batteries, which are called AGM/EFB batteries, you can observe the battery of your own car, and if you have the start-stop function, you can see these two English letters. This particular start-stop battery has a service life of at least three times higher than that of ordinary batteries, and is more reliable than ordinary batteries when started at low temperatures. Therefore, there are professional start-stop batteries, and we don't have to worry too much about the life of the battery.
Conclusion
Selected to use the automatic start-stop function,
For engine, starter and battery life
We don't need to worry,
They are all special accessories for start and stop,
Very long lifespan.
Finally, Xiaobian would like to remind you,
If the vehicle wads through water,
The automatic start-stop function must be turned off.
