How do cars start and stop automatically? Is automatic start-stop practical?

Start-stop is simply to stop and turn off the engine automatically according to the speed and its unique control gear, and the engine can start automatically when it has to move forward. The purpose of this system is to save gasoline and diesel, but it is not easy to save fuel when used in the wrong road section and will continue to damage the battery, because the power consumption of running the engine with the starter is very large. The current required for the instantaneous operation of medium and high horsepower engines is less than 500A, and the battery is larger, 65~85Ah- 12V, only 0.78~ 1 kWh.

If the vehicle runs safely on the congested road, the frequent start and stop of the vehicle will consume the battery power faster; If you can continue driving for several kilometers at high speed after leaving the congested road section, it is very likely to use the generator motor to restore power. But if you stop after leaving the congested road, the battery will definitely die. If you drive on this section for many times, the vehicle will not start and the service life of the battery will be shortened. The cost of replacing a set of upgraded batteries is quite high.

However, due to the improvement of technology and the gradual reduction of cost, even ordinary people still have the opportunity to experience the convenience of vehicle production. There is no end to the continuous progress of technology. Many technologies that can be called "high-tech" are applied to vehicles. Of course, not all high-tech technologies can be recognized by the masses, such as the automatic start-stop function of vehicles. In daily application, many people have some doubts about the automatic start and stop of the car, such as whether the engine will be damaged by frequent flameout or ignition; Will frequent ignition reduce the service life of batteries?

The premise is that everyone should remember that the starter and battery of vehicles equipped with automatic start-stop system are improved and dedicated! Some companies will continue to upgrade rechargeable batteries. Also, the main reason for the deterioration of engine characteristics is damage. More than 50% of engine damage is due to cold start, and the start and stop should be carried out under the condition of hot car! The key of engine internal structure depends on the lubrication of automobile oil. Because the start-stop time is so short, it is not easy for all the automobile oil added by the fuel injection pump to flow back to the engine oil pan, and a lot of automobile oil is stored on the parts, so it will not cause too much damage to the engine if it is operated frequently. For vehicles equipped with automatic start-stop system, it is recommended to use advanced automobile oil.
