What is the relationship between the transmission and the engine?

The relationship between the transmission and the engine is: the engine outputs power to the transmission, which controls the power and then transmits it to the car wheels. The functions of the transmission: 1. Change the transmission ratio to expand the variation range of driving wheel torque and speed, adapting to frequently changing driving conditions while keeping the engine working under favorable conditions; 2. Enable the car to reverse while keeping the engine rotation direction unchanged; 3. Use neutral gear to interrupt power transmission, allowing the engine to start, idle, and facilitating gear shifting or power output. The function of the engine is: to convert the thermal energy of gasoline into mechanical energy by expanding gas after combustion in a sealed cylinder, pushing the piston to do work.

What are the causes of steering deviation?

The causes of steering deviation are: 1. Loose tie rod ball joints; 2. Inconsistent braking distance on both sides; 3. Uneven tire pressure; 4. Steering wheel misalignment. The solutions for steering deviation are: 1. Check if the tie rod ball joints are loose; 2. Test the braking distance on both sides by applying the brakes; 3. Inspect the tire pressure on all four wheels to ensure uniformity; 4. Perform a four-wheel alignment. Precautions for using the steering wheel include: 1. Avoid excessive force when turning the steering wheel and refrain from sudden movements; do not turn the steering wheel when the vehicle is stationary; 2. Hold the steering wheel firmly when driving on bumpy roads to prevent loss of control and accidents; 3. Reduce speed when turning; 4. Gradually turn the steering wheel according to the curve's radius when entering a bend.

Should You Press the Clutch or Brake When Reversing?

When reversing, press the clutch. The steps are: 1. Press the clutch and shift into reverse gear, then slowly release the clutch to the semi-engagement point; 2. Hold the clutch steady and control the reversing speed using the semi-engagement of the clutch. Precautions for reversing include: 1. The vehicle must be stationary when shifting into reverse gear to avoid damaging the transmission; 2. Press the clutch before shifting to prevent gear grinding; 3. Avoid forcefully moving the gear lever—gently push the shift lever instead; 4. Lower the speed and reverse slowly, avoiding rapid acceleration. Semi-engagement refers to partially pressing the clutch pedal, keeping the clutch not fully connected to the engine.

Can Low-Speed Electric Vehicles Be Licensed?

Low-speed electric vehicles cannot be licensed because they are not included in the national motor vehicle product catalog. The broad definition of low-speed electric vehicles can include electric bicycles, electric motorcycles, electric tricycles, and low-speed electric cars. Low-speed electric vehicles refer to simple four-wheel pure electric vehicles with a speed below 70 kilometers per hour, generally with a maximum speed of 70 km/h, and their appearance, structure, and performance are similar to fuel-powered cars. According to regulations, the national standard for pure electric vehicles specifies a maximum speed not exceeding 80 km/h and a range greater than 80 kilometers.

How to use the start-stop function in Volkswagen Passat?

To use the start-stop function in the Volkswagen Passat, locate the start-stop button on the left side of the center console gear lever. Press the button to activate the function, and press it again to deactivate it. Taking the 2020 Volkswagen Passat as an example, it is a mid-size sedan with the following dimensions: length 4933mm, width 1836mm, height 1469mm, and a wheelbase of 2871mm. The 2020 Volkswagen Passat features a MacPherson strut front suspension and a multi-link rear suspension. It is equipped with a 1.4T turbocharged engine that delivers a maximum horsepower of 150PS, a maximum torque of 250Nm, and a maximum power output of 110kW, paired with a 7-speed dual-clutch transmission.

How to Operate the Delayed Headlight Shutdown?

The operation method for delayed headlight shutdown is: 1. Enter the settings on the central control screen; 2. Click on the headlights; 3. Access the headlight interface where you can find the option for delayed headlight shutdown; 4. Set it directly. The delayed headlight shutdown is also known as the 'coming home' function, which essentially means the headlights remain on for a period after the vehicle is turned off, providing external lighting for the driver after exiting the vehicle. After the engine is turned off, the system keeps the headlights on for an additional minute, offering external illumination for the driver post-exit. This feature is particularly convenient in areas without streetlights, as the delayed shutdown function serves as a lighting aid.

What is the correct way to brake a motorcycle?

Correct braking methods for motorcycles: 1. At high speeds, the braking force on the front wheel must be greater than that on the rear wheel; 2. At high speeds, the braking force on the front wheel must not cause the front wheel to lock up; 3. When braking uphill, the braking force on the front wheel can be appropriately increased; 4. When braking downhill, the braking force on the rear wheel can be appropriately increased; 5. During emergency braking, the braking force should be slightly less than the force required to lock the wheels; 6. On slippery roads, the rear wheel should brake before the front wheel. It is best to use both front and rear brakes together when braking, as the front brake is primarily designed to assist the rear brake in completing the braking process. Using only the front or rear brake alone will not achieve the shortest braking distance; combining both will yield better braking performance.
