The automatic start-stop technology of the motor actually appeared in the 1930s, but it was not widely used in traditional vehicles until the mid-1980s. In 1984, the automatic start-stop technology* was applied to the Volkswagen Golf Diesel motor. Subsequently, many car brands have a strong interest in the technology, began to test the system in small batches, such as Fiat Mazda, Honda, Citroen, General and so on. In 2007, the technology began to be used in high-volume applications on BMW models.

How to use the start-stop system?

The automatic start-stop system automatically turns on by default when the key is powered on. To close it, just press the button. The automatic start-stop system is very convenient to use. As long as the brake pedal is directly pressed during driving, the motor will automatically stop after about two seconds of stopping the vehicle. The brake pedal will remain on and the motor will remain closed. As soon as the brakes are released, or the steering wheel is turned, or the gear position is switched, the motor will automatically ignite immediately, and the accelerator can be started immediately. The whole process is in the D-range state. The manual block car is a loose-fitting clutch that is turned off, and is turned off and automatically restarted.

So, what are the advantages of automatic motor start-stop technology?

This is of course obvious. After fuel-saving, automatic start-stop, the motor is still working in a strict sense. It is in normal operating temperature, temporarily "sleeping", but the pulley stops and the speed is lowered. Therefore, there is no problem of high fuel consumption in an instant. According to GM, after the automatic start-stop system, the fuel-saving rate can reach about 10% under actual use, and the carbon dioxide emissions can be reduced by 15.1g per 100 kilometers. The German Bosch company also did this experiment before, and they concluded that the average fuel economy is about 8%-15%. The more congested, the larger the displacement, the more obvious the effect. The China Automotive Technology and Research Center has also tested that the fuel economy rate even reaches 7%-27%.

So for many people, is the damage motor really true?

Some people think that the automatic start and stop function * do not use, because frequent start and stop will cause the piston to wear, the resulting metal debris will also wear other key components of the motor, and the damage to the motor over time. Frequent start-stop motors are indeed a big deal of motor wear, but they all ignore the fact that most of the motor wear occurs when the cold car starts. Therefore, frequent start-up does not cause much wear on the motor. The motor interior is mainly lubricated by oil film. Since the time of automatic start-stop is very short, the oil that is pumped by the oil pump will not flow back, and a lot of oil remains on the parts. It has no effect on the speed and time of the start and the hot start.

Since the automatic start-stop type has a greater use strength for the starter motor and the battery, the relevant components have been reinforced and optimized, so that under normal driving conditions, the reliability of the entire power system will be greatly improved, so I am worried about this. However, the enhanced starter and battery maintenance costs will also be higher than the normal starter and battery.

Precautions for using the automatic start/stop function

If your vehicle has an automatic start-stop function, you may see some notes on its use in the manual. Due to the technical principle of automatic start-stop, you should understand its characteristics in some scenarios: First, if the vehicle When driving to a relatively ramp, try not to turn on the automatic start and stop, because the automatic start and stop time is very short, but the start and stop of the motor on the ramp may cause insufficient brake assistance.

Secondly, when the southern weather hot air conditioner is running at full power, * will also turn off the automatic start and stop function, because the air conditioner needs relatively large power consumption, and the body power may not be enough to drive the air conditioner when the motor is stopped, which will make the car The passengers on the bus feel uncomfortable, so there is no need to save this.
