Why is there a strange noise when braking while reversing?

The reason for the strange noise when braking while reversing is due to the moving caliper hitting the caliper bracket during the reverse process. Below are the relevant explanations: 1. Radar system: When the car moves from the warning zone into the danger zone, the radar system automatically activates the braking device to control the car's reverse movement. The principle is based on an ordinary reverse radar system, with the addition of a servo mechanism that has a braking function. When the car moves from the warning zone into the danger zone, the controller sends a control signal to the braking servo, which immediately activates to automatically stop the car from moving backward, ensuring safe reversing. 2. Braking: When driving forward and braking, there is no 'play gap' at the lower connection point with the brake bracket, so no noise occurs. However, when braking in reverse, the brake caliper moves upward and hits the upper bracket, producing the strange noise.

Which is better, supercharger or turbocharger?

Both supercharging methods have their own advantages and disadvantages. The following are the differences between a supercharger and a turbocharger: 1. Power: A supercharger uses the engine's own power to drive a compressor for boosting. 2. Consumption: The supercharger consumes the engine's power, and its speed changes with the engine speed, avoiding boost lag. It performs exceptionally well at low engine speeds but is limited by the engine speed, resulting in insufficient boost at high engine speeds. 3. Exhaust: A turbocharger utilizes the exhaust gases produced by the engine to drive a turbine in the exhaust pipe, which in turn drives a turbine in the intake pipe for indirect boosting, without consuming the engine's power. 4. Speed: The turbocharger operates at extremely high speeds, providing several times higher boost pressure than a supercharger. However, due to the inertia of the turbine and the significant resistance of the intermediate bearings, the turbine speed does not increase simultaneously when exhaust gases suddenly increase, which is known as turbo lag.

Why Has the Car Horn Sound Become Quieter?

Car horn sound may become quieter due to reasons such as excessive battery discharge, contact point erosion or poor contact, as well as loose or poor contact at terminal connections. Below is a detailed introduction to car horns: 1. Introduction: The horn is the audio signaling device of a car. During driving, the driver can emit necessary audio signals as needed and required to warn pedestrians and alert other vehicles, ensuring traffic safety, while also being used for urging and signal transmission. 2. Working Principle: The car electric horn produces sound through the vibration of a metal diaphragm. The car electric horn consists of an iron core, magnetic coil, contacts, armature, diaphragm, etc. When the driver presses the horn switch, current flows through the contacts to the coil, generating magnetic force that pulls down the armature, forcing the diaphragm to move. The movement of the armature causes the contacts to open, interrupting the current and causing the coil's magnetic force to disappear. The diaphragm, along with the armature, returns to its original position under its own elasticity and the spring plate's action, closing the contacts again to reconnect the circuit. Current then flows through the contacts to the coil, generating magnetic force and repeating the above actions. This cycle repeats continuously, causing the diaphragm to vibrate repeatedly and thus producing sound.

Why is the car idle unstable?

There are several reasons for unstable car idle, including oil accumulation and carbon deposits in the throttle body, as well as dirty or clogged intake passages, which can cause idle fluctuations. Carbon deposits or oil in the throttle body are the most common causes of unstable idle. Below are some related reasons for unstable car idle: Spark plug failure: Weak sparks from faulty spark plugs can also lead to carbon buildup. Carbon deposits can be cleaned to restore spark plug activity, but some spark plugs may be nearing the end of their lifespan, resulting in reduced performance. Fuel system blockage: Blockages in the fuel system, particularly in the fuel injectors, or faults in the intake manifold can cause insufficient fuel supply pressure, leading to poor fuel atomization. This disrupts the air-fuel mixture ratio, resulting in incomplete combustion and related issues. Sensor failure: Faulty sensors can prevent the ECU from accurately controlling the air-fuel ratio. Common sensor failures include the coolant temperature sensor, oxygen sensor, and throttle position sensor. The coolant temperature sensor is typically installed on the engine block or cylinder head water jacket, directly contacting the antifreeze to measure temperature and provide reference data to the ECU.

What is the actual range of AION Y?

AION Y has a range of 600km. Here is some extended information: 1. Exterior: The most eye-catching feature of GAC AION is its two front headlights, which adopt an exaggerated design language. The "7"-shaped design perfectly showcases the fashionable appeal favored by young people. The side curves of the car body look very comfortable, and the wheels feature a unique and attractive design. 2. Space: The dimensions of the car are 4410*1870*1645mm, with a wheelbase of 2750mm. Although it appears compact, the interior space is well-utilized, offering a surprisingly spacious feel when seated inside. 3. Interior: The GAC AION AION Y fully embodies a sense of technology. The large central control screen is striking, and the instrument panel uses a liquid crystal electronic display, showing all vehicle information. The three-spoke steering wheel and rotary gear selector further enhance the car's technological feel. Additionally, 5G network support has been added, elevating the car's intelligence to a higher level. 4. Power: Taking the AION Y 2021 80 Yuexiang Tech Edition as an example, it is equipped with a 135kW electric motor, delivering a peak torque of 225N.m.

Process of Adding E-class License

Taking Shanghai as an example, the specific process for adding an E-class license to a C1 driver's license is as follows: Procedure for Adding Permitted Driving Types: The applicant should bring the required materials to a local motor vehicle driver training institution to register. The institution will then handle the procedure for adding permitted driving types at the vehicle management office in the respective jurisdiction. Completion of Subject Tests Within the Validity Period: After the applicant passes the Subject 1 test, the vehicle management office will issue a "Learning to Drive Certificate" (valid for three years) within one working day. The applicant must complete Subject 2 and Subject 3 tests within the validity period. If the tests are not completed within the validity period, the passed subject results will be invalidated. Receipt of the Motor Vehicle Driver's License: After the applicant sequentially passes Subject 1, Subject 2, and Subject 3 tests, the vehicle management office will produce the motor vehicle driver's license within one working day. The applicant will then receive education on safe and civilized driving common sense and traffic accident case warnings, participate in a pre-license oath ceremony, and be issued the motor vehicle driver's license.
