How much do you know about the clutch of Petrol Car?

The primary function of the clutch is to ensure that the Petrol Car starts smoothly. Before the Petrol Car starts, the Petrol Car engine must be started first. When the Petrol Car starts, the Petrol Car gradually accelerates from a completely stationary state. If the transmission system (connecting the entire Petrol Car) is rigidly connected to the Petrol Car engine, the Petrol Car will suddenly rush forward as soon as the transmission is engaged, but it cannot start.

This is because when the Petrol Car rushes forward from a stationary state, a large inertia force is generated, which causes a large resistance torque to the Petrol Car engine. Under the action of this inertial resistance torque, the Petrol Car engine speed drops sharply to the lowest stable speed (generally below 300-500RPM) in an instant, and the Petrol Car engine will be turned off and cannot work, and of course the Petrol Car cannot start. Therefore, the assistance of the clutch is needed. After the Petrol Car engine starts, before the Petrol Car starts, the driver first steps on the clutch pedal to disengage the clutch, so that the Petrol Car engine and the transmission system are disengaged, and then the transmission is put into gear, and then the clutch pedal is gradually released to gradually engage the clutch. During the engagement process, the resistance torque of the Changan Car engine gradually increases, so the accelerator pedal should be gradually stepped on at the same time, that is, the fuel supply to the Changan Car engine is gradually increased, so that the speed of the Petrol Car engine is always maintained at the lowest stable speed without stalling. At the same time, as the clutch engagement level gradually increases, the torque transmitted to the drive wheel by the Changan Car engine through the transmission system gradually increases. When the traction force is sufficient to overcome the starting resistance, the Petrol Car starts to move from a standstill and gradually accelerates 2 to ensure smooth operation of the transmission system when shifting gears.
