After removing the dual-mass flywheel, gently shaking it by hand can produce a "clattering" sound. The following describes several functions of the flywheel: 1. Energy storage and speed stabilization: The flywheel uses its own moment of inertia to store part of the work input to the crankshaft during the power stroke, which is used to overcome resistance in other strokes, driving the crank linkage mechanism past the top and bottom dead centers, ensuring the crankshaft's rotational angular velocity and output torque are as uniform as possible, and enabling the engine to overcome short-term overloads. 2. Driving component: It serves as the driving component of the friction clutch, engaging and disengaging with the clutch, transmitting the engine's rotational force through the transmission to the drive wheels.

Should the front or rear fog lights be turned on during the Subject 3 test?

During the Subject 3 test, both front and rear fog lights are turned on simultaneously. When the front fog lights are activated, the rear fog lights will also turn on at the same time. Method to turn on fog lights: After turning on the parking lights, you can then activate the fog lights. Among these, the front fog lights can be turned on individually. The rear fog lights can only be activated together with the front fog lights and cannot be turned on separately. Styles of fog light switches: There are mainly two styles of fog light switches: button-type and rotary-type. Different car manufacturers may have their preferred methods for activating fog lights. The button-type fog light switch is characterized by its ease of operation—pressing it directly achieves the desired function. The rotary-type fog light switch is integrated into the left stalk.

What's the reason for the brake not releasing?

If the brake does not release, you should take it to a repair shop for maintenance and replace the brake pads. The following is a detailed introduction to the handbrake: 1. Introduction: The professional term for the handbrake is auxiliary brake. Unlike the principle of the brake, it uses a steel wire cable connected to the rear brake to stop the car. 2. Usage: Long-term use of the handbrake will cause the steel wire to undergo plastic deformation. Since this deformation is irreversible, long-term use will reduce its effectiveness, and the handbrake's travel will also increase. Here are some extended details: 1. Maintenance: Regularly perform appropriate maintenance and inspection on the car's handbrake. Some people, due to irregular maintenance, often need to lift the handbrake twice to stop the car. If you are careless when parking, the car may slightly move backward, so the use and maintenance of the handbrake should not be underestimated. 2. Effective point of the handbrake: You can park the car in a relatively quiet place, slowly pull up the handbrake, and count the clicks of the ratchet as you pull until the handle reaches the end. Then calculate the 70% position of the total number of clicks. This position is the effective working point of the handbrake handle.

Is it faster to follow the system arrangement or choose independently for Subject 2?

Following the system arrangement for Subject 2 will allow you to take the test faster than choosing the exam session independently. Benefits of following the system arrangement: The advantage of following the system arrangement is a higher success rate for appointment, but you cannot independently choose the exam time or session, as these are randomly assigned by the system. The benefit of choosing the exam session independently is that both the exam time and session can be selected at your discretion. Definition of Subject 2: Subject 2, also known as the small road test, is part of the motor vehicle driver's license assessment. It is the abbreviation for the field driving skills test. For small vehicles C1 and C2, the test items include five mandatory components: reversing into a garage, parallel parking, stopping and starting on a slope, turning at a right angle, and driving on a curved path.
