We directly on the dry goods, "automatic start and stop" is not a chicken rib, it is a new fuel-saving technology developed by car companies, its matching will not affect the durability and stability of the vehicle, but help to reduce the fuel consumption of the vehicle, according to the actual results reflected by the owners, automatic start and stop can reduce the fuel consumption of the vehicle by about 2% to 4%. Let's give you a detailed introduction to the automatic start-stop!
Definition of automatic start-stop
Automatic start and stop refers to the fact that when the owner needs to stop temporarily, such as waiting for the red light or the roadside and other people, the engine will automatically turn off, when the owner steps on the accelerator to start, the engine will automatically start, according to the engine frequency of start, turn off this function, "automatic start and stop" has its English abbreviation STOP & START, referred to as SST intelligent fuel saving system. If we go to a 4S store, we will hear the sales staff of the 4S store introduce us to the "advanced" function of automatic start and stop, which can effectively cope with special road conditions such as traffic jams and urban road driving.
Automatic start-stop is not a chicken rib
Many old drivers are very uncomfortable with its appearance when they first contact the automatic start-stop function. In the case of red lights such as vehicle parking, the engine suddenly turns off, when the car Xiaobai first contacts this function, it will be mistaken for the engine is broken, after releasing the brakes, the engine suddenly starts, making the car Xiaobai busy, and the frequent start of the engine and the shutdown will also produce a certain driving frustration, affecting the driving fluency and riding comfort of the vehicle.
But as long as you are used to the automatic start and stop of this function, absolutely can not help but give it praise, such as in the case of traffic jams, the owner often stops and goes, each stop takes a long time, in this case, the engine automatic shutdown can effectively reduce the fuel consumption of the vehicle; in order to make the automatic start and stop of this function more comfortable, engineers developed the Autohold function, when the owner opens the Autohold function, after the vehicle stops, the brake system will automatically apply the braking force, This prevents the vehicle from slipping, which is a perfect match for automatic start and stop. After the owner stops, the engine turns off, under the action of Autohold, the car automatically applies braking force, the owner can release his feet to rest and rest, no need to pull the handbrake, do not need to step on the brakes and other unnecessary actions, if you want to let the vehicle start, directly step on the accelerator, after the engine starts, the braking force is released by itself, after starting.
Automatic start-stop does not affect the durability of the engine
You may ask, does frequent engine start affect the durability and reliability of the vehicle? Of course not, the application of new technologies must not affect the performance of vehicles, which is the premise of automobile research and development. In the process of automatic start-stop function, the first thing to be studied is of course the durability of the engine, and will the frequent start of the engine make it scrapped in advance? According to the current research results, the frequent start and shutdown of the engine in the case of cold car will increase the wear of the engine, resulting in excessive carbon deposition and other phenomena in the engine, but if in the case of hot cars, frequent start will hardly affect the durability and stability of the engine.
Therefore, when the automatic start and stop is working normally, it has certain conditions, one of which is that the water temperature and oil temperature of the engine must reach the appropriate value to ensure the durability and stability of the vehicle.
Although many car owners do not agree with the automatic start-stop function, its benefits are real, and it has almost no impact on the durability and stability of the car.
