The price of oil has seen "four successive rises" since Chinese New Year, and is now back in 7 yuan era. Many car owners have to think about how to save fuel. In fact, when a car leaves factory, question of how to control amount of oil is really considered, just like an automatic start-stop function set up to save fuel. But for this so-called fuel-saving device, many old drivers turn it off as soon as they get in car, because it is recognized as a "fuel geek" and can steal a quarter of your car's fuel.
Perhaps many will have a question, but isn't it about fuel economy, how can he become a "fuel rat"? While original intent of design was indeed to save fuel, after actually using it, many people find feature too tasteless: instead of saving fuel, it increases fuel consumption and in some cases even creates unnecessary danger.
First of all, it has a detrimental effect on engine. If frequency of automatic start, stop and start is too high, it will undoubtedly greatly increase friction of engine. Over time, it will inevitably lead to serious engine wear and worse, even lead to shortened engine life and premature disposal. In addition, when driving uphill, you cannot use automatic start and stop, because probability of skidding is very high, and danger is obvious.
In addition, in recent years, number of cars moving in a straight line has increased, and traffic jams have become common, especially during rush hour, when you even have to wait at intersection for dozens of red traffic lights. automatic start and stop, then your fuel consumption is rated as unstoppable. In addition, rhythm of starting and stopping again and again is extremely inconvenient for passengers.
Another point is that auto start and stop cannot be used on rainy days, especially when it rains heavily. Once engine accidentally enters water, even if you press brake a little, computer will react, maybe . It will automatically start car, and if engine fails because of this, then all losses, repairs and even cost of replacing engine falls on you, because other insurance companies have reasons to refuse compensation.
