The functions are as follows: 1. Ensure smooth starting of the car: The driving force is insufficient to overcome the huge inertia generated by the car's forward rush, causing the engine speed to drop sharply and stall. 2. Facilitate gear shifting: During driving, different transmission gears are frequently used to adapt to constantly changing driving conditions. 3. Prevent overload of the transmission system: Since the clutch transmits torque through friction, when the load in the transmission system exceeds the torque that friction can transmit, the driving and driven parts of the clutch will automatically slip, thereby preventing overload of the transmission system. 4. Reduce torsional vibration impact: The working principle of the car engine determines the instability of its output torque.

The clutch is a crucial helper in manual transmission cars. Anyone who's driven for over a decade knows that pressing the clutch pedal disengages the engine from the gearbox, allowing smooth gear changes without stalling the car. Especially when starting at intersections or on slopes, gradually releasing the clutch while coordinating with the accelerator ensures smooth movement, preventing sudden jerks that could be dangerous. Shifting gears without depressing the clutch feels like hitting a wall and may damage the engine or transmission. The clutch also helps cut off power when parking, saving you from constantly pressing the brake pedal. Remember to regularly check clutch plate wear; otherwise, slipping gears can cause delays. Simply put, it's the soul of a manual car—without it, nothing works.

What Causes the Buick Excelle to Shake a Few Times and Stall Automatically?

It may be caused by a camshaft solenoid valve issue leading to engine stalling. It is recommended to disconnect both the intake and exhaust camshaft solenoid valves and try starting the engine again. If it still fails to start, it should be handed over to a 4S shop for inspection and repair. Below is an analysis of the reasons for car stalling: 1. Electrical component failure: This problem is usually related to the ignition coil, capacitor, or electronic ignition module. The car may start initially, stall after a while, start again, and then stall once more. 2. Fuel system failure: This includes a damaged fuel pump, ruptured fuel line, clogged carburetor fuel inlet, or an empty fuel tank. In such cases, the car may still start, but with great difficulty. 3. Sensor failure: Faults in sensors such as the throttle position sensor, air flow sensor, intake pressure sensor, crankshaft position sensor, or camshaft position sensor can also cause stalling issues.

What are the hazards of not repairing car paint in time?

The hazards of not repairing car paint in time are as follows: 1. Color difference: Not repairing the paint in time will cause color difference, and improper paint repair can also lead to color difference. Some car paint repairs require color matching, and the requirements for spraying process are relatively high. If the color matching is inaccurate or the spraying process is poor, color difference can easily occur. 2. Low paint durability: Paint repairs require the use of putty to smooth out the scratched areas. Not repairing the paint in time will result in lower hardness compared to the original car paint. Once the repaired area is subjected to force, the paint surface is prone to blistering and peeling. 3. Car depreciation: Generally, not repairing the paint in time will cause the car to depreciate, and the larger the area that needs to be repaired, the higher the degree of depreciation.

What do driving brake and parking brake respectively mean?

Driving brake, commonly referred to as the brake, is used to slow down or stop the vehicle while in motion. Parking brake, on the other hand, is the brake used when the vehicle is stationary, also known as the handbrake. Below is an introduction to driving brake and parking brake: 1. Different functions: The main function of the parking brake is to prevent the vehicle from sliding forward or backward, while the driving brake is primarily used for deceleration and stopping; the brake used during driving is called the driving brake. 2. Different principles: When starting on a slope, the parking brake requires the driver to manually release the handbrake or skillfully coordinate the throttle and clutch for a smooth start. Due to the presence of the transmission, the driving brake requires corresponding adjustments based on different gear ratios; the higher the gear, the smaller the gear ratio. 3. Different braking effects: The parking brake only has a braking effect on the two rear wheels, whereas the driving brake is used while the vehicle is in motion and is a hydraulic brake, providing braking effect on all four wheels.

Can I Apply for a Vehicle License When Buying a Used Car?

Buying a used car allows you to apply for a vehicle license. Below are the specific details for purchasing a used car: 1. Prepare the required documents for the used car transaction: Before applying for a vehicle license for a used car, you need to prepare the necessary documents. These include the vehicle license, vehicle registration certificate, vehicle purchase tax certificate, road maintenance fee receipt, insurance policy, vehicle and vessel usage tax certificate, and ID card. The used car transaction contract must be supervised by the industrial and commercial department, with both the buyer and seller holding a copy. The contract must be filed with the industrial and commercial department before proceeding with vehicle transfer or registration change procedures. 2. Pay attention to the vehicle's condition: When purchasing a used car, it's important to check the vehicle's condition, such as the production date and mileage. The mileage reflects how long the car has been driven, directly indicating its remaining lifespan.
