The functions of a rear axle differential lock are as follows: 1. When a car is driving on a curve, there is a certain difference in the rotational speed of the inner and outer wheels. The outer wheel travels a longer distance and thus rotates faster than the inner wheel. The differential allows for this difference in wheel speed, enabling reasonable torque distribution between the left and right wheels during turns to achieve optimal turning performance. 2. The rear axle differential lock is located between the two rear wheels of the vehicle. It compensates for the spinning caused by a wheel losing traction in a standard differential and also allows for extensive drifting maneuvers. 3. The rear axle differential lock enhances performance. During accelerated cornering, the output torque and centrifugal force can cause the inner wheel to lift off the ground or slip. The rear axle differential lock helps the driver increase cornering speed, offering greater high-speed capability and controllability advantages compared to a standard differential.

Is it mandatory to display the motor vehicle inspection compliance sticker?

Nowadays, the annual vehicle inspection sticker has been digitized and no longer needs to be physically displayed on the vehicle. Below is relevant information about vehicle inspections: 1. During the inspection, tailpipe emissions will be tested for compliance: Vehicle emissions testing involves the oxygen sensor and catalytic converter. Their optimal operating temperature ranges between 400 to 800 degrees Celsius, so it's recommended that owners warm up their vehicles in the inspection area before the emissions test to increase the pass rate. 2. Clean your vehicle: Prior to the annual inspection, owners should thoroughly clean their vehicles. Cleaning the body, engine compartment, and chassis in advance facilitates the inspection process for technicians and improves the chances of passing. 3. The vehicle management office will inspect the vehicle's lighting: If the vehicle's lights are found to be either too dim or too bright, it will be deemed non-compliant and fail the inspection. It's advisable to restore the headlights to their original condition before the inspection to ensure compliance.

What Are the Disadvantages of a Car Sunroof?

Disadvantages of a car sunroof: higher cost, reduced body rigidity and safety coefficient, and the sunroof is prone to accumulating dust. Below is relevant information: 1. Higher cost: Whether you choose a car with a sunroof or install one afterward, it requires additional expenditure. 2. Reduced body rigidity and safety coefficient: In the event of an accident, when the vehicle's side is impacted or the vehicle rolls over, the B-pillar is the part that undergoes the most significant test of body rigidity. The B-pillar runs circularly through the central area of the body, where the sunroof is located. Some sunroofs, in pursuit of a larger area and aesthetic appeal, minimize the roof rail of the B-pillar. When a side impact occurs or the vehicle rolls over, the body is more susceptible to compression and deformation.

Why Can't You Sleep in the Car with the Air Conditioning On?

Sleeping in the car with the air conditioning on carries the risk of poisoning. Here are the specific reasons: 1. Risk of carbon monoxide poisoning: If there is no wind, carbon monoxide can accumulate around the car, and the concentration increases over time. At this point, if the car is set to external air circulation, a large amount of carbon monoxide from outside could be drawn into the car, leading to carbon monoxide poisoning. 2. Risk of unconsciousness and brain hypoxia: If the windows are tightly closed and the air conditioning is set to internal circulation while sleeping in the car for a long time, the confined space of the car means that human breathing will cause the oxygen inside the car to decrease, while the exhaled carbon dioxide will increase. When the concentration of carbon dioxide in the car reaches a certain level, a person may experience unconsciousness and brain hypoxia, which can be fatal in severe cases.

How to Disable the Engine Immobilizer?

Engine immobilizer deactivation method: 1. First, turn on the vehicle and insert the key to ensure the power is on; 2. Then, wait until the immobilizer light on the dashboard starts flashing and observe the dashboard; 3. Next, turn off the vehicle's power and wait for about ten minutes before turning the power back on; 4. At this point, the immobilizer light will flash again, and then repeat the above steps three times. The engine immobilizer system works as follows: The car's ignition key contains an electronic chip, each with a fixed ID (equivalent to an identification number). The car can only start when the key chip's ID matches the ID on the engine side. Conversely, if they do not match, the car will immediately cut off the circuit automatically, preventing the engine from starting.

What does it mean when the ABS light appears on the car dashboard?

The ABS light appearing on the car dashboard indicates a fault in the ABS system, reminding the driver to drive carefully and have it inspected and repaired as soon as possible. Common causes of the fault include: damaged or dirty wheel speed sensors (clean or replace the sensors); damaged or dirty signal rings (clean or replace the bearings); damaged ABS control unit (replace the control unit); loose or broken ABS wiring (repair or replace the wiring harness). The Anti-lock Braking System (ABS) automatically controls the braking force during car braking to prevent the wheels from locking up, keeping them in a state of rolling and sliding (with a slip ratio of about 20%), ensuring maximum traction between the wheels and the road.
