1. Move quickly. The shift time of automobile dual clutch is very short, which is faster than the speed of manual gearbox, only less than 0.2 seconds.

2. Save fuel. Automobile dual clutch can save a lot of fuel because it eliminates the interruption of torque, that is, it keeps the power of the engine in use and always works in the best state.

Step 3 be comfortable. Because of the fast shift speed, DCT shifts gears smoothly every time, and the sense of frustration is very small, which is difficult for the human body to detect.

2. Disadvantages of automobile dual clutch:

1. Cost problem. The structure of automobile dual clutch is complex, and the manufacturing process requirements are relatively high, so the cost is relatively high. So we see that vehicles with dual clutches are all mid-to high-end models.

2. Torque problem. Although the dual clutch gearbox can definitely meet the requirements of ordinary vehicles in terms of bearing torque, it is still not enough for intense use. Because if it is a dry clutch, it will generate too much heat, while the friction of a wet clutch is not enough.

Extended data:

The clutch is located between the engine and the transmission. It is the "switch" of power transmission between the engine and the transmission. It is a transmission mechanism that can not only transmit power, but also cut off power.

Its main function is to ensure that the car can start smoothly, reduce the impact load of the speed change gear and prevent the transmission system from being overloaded when shifting gears. In general cars, gear shifting is realized by the disengagement and engagement of the clutch, and the power transmission is temporarily interrupted between disengagement and engagement.
