How to Determine a Car's Production Date from Its Glass

The method to determine a car's production date from its glass is as follows: 1. First, the number represents the production year of the glass, indicating the last digit of the production year. If the vehicle's manufacturing date is in 2007 or 2008, then the glass year number 8 should represent 2008. The difference between the glass and the vehicle's production date will not exceed 10 years. 2. The small black dots indicate the production month of the glass. If you carefully observe the glass of other vehicles, you will notice that some glasses have the black dots in front of the number, while others have them behind the number. 3. If the black dots are in front of the number, subtract the number of dots from 7; if the black dots are behind the number, subtract the number of dots from 13. The result will be the production month of the glass.

Reasons for Brake Disc Noise

Brake disc noise is generally caused by insufficient tension in the brake return spring, excessively hard brake pad material, or the brake pads being installed too close to the brake disc. Here are some introductions about brakes: 1. Currently, there are disc brakes and drum brakes. Many older vehicles often feature front disc and rear drum configurations. 2. Many modern vehicles use disc brakes on both front and rear wheels because disc brakes have better heat dissipation than drum brakes. During high-speed braking, they are less prone to thermal fade, resulting in better high-speed braking performance. 3. Disc brakes have inferior braking performance compared to drum brakes during low-speed cold braking, and they are more expensive than drum brakes.

What is the name of the glass at the front of the car?

The glass at the front of the car is called the windshield, also known as the front windshield. As the name suggests, its main function is to block the wind that blows towards the driver while driving. Here is some relevant information about windshields: 1. Initially, windshields were designed to be upright. However, during use, people found that this installation method increased the car's resistance and was not aesthetically pleasing. Therefore, later car windshields were installed at an angle to reduce resistance, which in turn helps to decrease fuel consumption. 2. The windshields of large trucks still maintain an upright design because the weight of large trucks is significant, making this resistance negligible for them. Modern windshields are mostly made of tempered glass, which has high strength and is generally not easy to break.

What Types of Transmissions Do Cars Have?

Automobile transmissions can be classified into Hydraulic Automatic Transmission (AT), Continuously Variable Transmission (CVT), Automated Manual Transmission (AMT), and Dual-Clutch Transmission (DSG). The details are as follows: 1. AT consists of a torque converter, planetary gears, and a hydraulic control system, achieving variable speed and torque through hydraulic transmission and gear combinations. The torque converter is the most critical component, comprising a pump wheel, turbine, and guide wheel, which functions to transmit torque and act as a clutch. 2. Compared to AT, CVT eliminates the complex and bulky gear combination transmission, instead using two sets of pulleys. Speed variation is achieved by altering the contact radius of the belt between the driving and driven pulleys. Since gear transmission is omitted, the transmission ratio can be freely adjusted, resulting in smoother shifting without sudden gear jumps. 3. AMT, like AT, is a stepped automatic transmission. Based on a conventional manual transmission, it incorporates a microprocessor-controlled electric device that replaces the manual operations of clutch engagement/disengagement, gear selection, and shifting, enabling automatic gear changes. 4. DSG transmissions are distinctly different from traditional automatic transmissions, as DSG does not use a hydraulic torque converter from the outset. This transmission is not produced based on the conventional automatic transmission concept. The engineers who designed DSG embarked on an innovative technological path, ingeniously combining the flexibility of manual transmissions with the convenience of traditional automatic transmissions.

What to Do If Too Much Transmission Fluid Is Added?

It is recommended to drain some of the excess transmission fluid. This is because the lubrication at the crankshaft relies on the stirring action of its own rotation, so the fluid level should not be too high. Otherwise, it increases stirring resistance, and excessive oil splashing onto the piston area may raise the chance of oil leakage. More information about automotive transmissions is as follows: 1. Transmissions can be divided into automatic and manual types, and their fluid replacement frequencies vary accordingly. 2. Problems may arise if transmission fluid is not changed over a long period. Transmission fluid deteriorates and evaporates under high-speed and high-temperature conditions, accelerating the wear of mechanical components. In severe cases, internal transmission parts may be damaged. Without fluid replacement, the vehicle may experience weak starts when cold. 3. During driving, the vehicle may exhibit slight slipping and similar issues. Prolonged neglect of fluid changes leads to thickening of the transmission fluid, which can block the transmission cooler, causing excessively high fluid temperatures and further accelerating wear.

How to Use the S Gear in an Automatic Transmission?

The usage method of the S gear in an automatic transmission is as follows: 1. The S gear is suitable for traffic jams and short-distance competitive races. 2. When using the S gear, pay attention to safety, control the speed, and maintain a safe distance. It is usually used for climbing slopes and quick overtaking. Here is some relevant information: 1. The S gear is the sports mode of the car ("S" stands for "Sport"). In S gear sports mode, the throttle response speed becomes faster, the engine speed is maintained in a higher range, and the gear shift timing is delayed, keeping the vehicle in a high-power output state. 2. In terms of fuel consumption, because the fuel injection volume increases at high speeds, the fuel consumption in S gear mode is much higher than in normal mode. Moreover, since the S gear only delays upshifting without changing other working conditions, it will inevitably increase the load on the transmission in a short time, accompanied by a rise in temperature, which will also increase wear. However, using the S gear also has benefits for the vehicle. Frequently driving at high speeds is beneficial for removing carbon deposits in the engine. However, if you want to remove carbon deposits, it is recommended to drive on the highway regularly for better results.
