S gear is the sport mode of a car (S stands for sport). In S gear sport mode, the transmission can shift freely, but the shifting timing is delayed, keeping the engine at high RPM for a longer time. This allows the car to operate at low gear and high RPM for an extended period, resulting in greater torque output and acceleration. Below is an introduction to the S gear: S gear in terms of vehicle movement: As a sport mode, it naturally excels in vehicle movement. Generally, when climbing a slope, engaging the S gear provides greater power, making driving easier. Similarly, when overtaking, it can quickly boost power output to achieve the overtaking goal. Additionally, the S gear helps increase engine load in a short time, which aids in removing carbon deposits from the engine. The function of + and - in S gear: The + and - in S gear refer to the manual-automatic transmission, a more advanced and sophisticated feature typically found in slightly more luxurious vehicles. Its main function is to switch the gear into manual mode. When shifting from D gear to S gear, it becomes manual first gear; + represents manual second gear, with the highest being third gear. Essentially, it follows the principle of a manual transmission but is more intelligent. Although the S gear delivers strong power, it requires greater torque output, leading to relatively higher fuel consumption.

Will Changing Lanes Over a Solid Line Definitely Be Captured by Cameras?

When a vehicle changes lanes over a solid line at an intersection, it is highly likely to be captured by cameras due to their frequent shooting intervals. Changing lanes over a solid line is a traffic violation that involves disobeying prohibitory signs, punishable by a three-point deduction and a fine. Continuous lane changes can be determined by the vehicle's turn signals. For example, a vehicle will activate its turn signal in advance before changing lanes, indicating the direction of the intended lane change. After signaling, the driver must check the opposite lane and rear vehicles before proceeding with the lane change. Speed reduction markings are divided into longitudinal deceleration lines and transverse deceleration lines, typically placed near toll booths, exit ramps, or other areas requiring vehicles to slow down, marked with white dashed lines. Longitudinal deceleration lines usually consist of a series of diamond-shaped dashed lines parallel to the lane dividers, commonly found on bridges, turns, or other locations. Their primary purpose is to create a visual narrowing effect, inducing a sense of pressure that prompts drivers to slow down automatically in designated areas. The photo enforcement system for changing lanes over a solid line uses ground-pressure magnetic induction loops. The principle of photo capture is as follows: when the front wheels of a vehicle pass over the induction loop on the ground, the first photo is taken electronically; when the rear wheels pass over the induction loop, the second photo is taken; and when the vehicle crosses the intersection and passes over the induction loop on the opposite side, the third photo is taken. The system for capturing lane changes over solid lines operates 24/7, and the images and related data are retained for one week. Minor violations of changing lanes over solid lines that do not result in major safety incidents are usually not captured. Temporary license plates used on new vehicles, due to material issues, are often difficult to capture clearly by electronic enforcement systems.

Can the Dash Cam Record Conversations Inside the Car?

Dash cams can record conversations inside the car. The specific details are as follows: Dash cam: an instrument that records images, sounds, and other related information during vehicle travel. After installing a dash cam: it can record video images and sounds of the entire driving process, providing evidence for determining traffic accident liability. Different dash cam products have different appearances, but their basic components include: Main unit: including a microprocessor, data storage, real-time clock, display, lens module, operation keys, printer, data communication interface, and other devices. If the main unit does not include a display or printer, it should have corresponding data display and print output interfaces. Speed sensor. Data analysis software. Infrared camera, an essential component for night vision functionality.

What does aftermarket parts mean?

Aftermarket parts refer to accessories produced by manufacturers not authorized by the original automobile manufacturer. The differences between original equipment manufacturer (OEM) parts and aftermarket parts are as follows: There are conceptual differences between OEM parts and aftermarket parts: OEM parts are generally products ordered by automobile manufacturers and their component suppliers. These products bear the manufacturer's brand and are ordered by the automobile manufacturer. Aftermarket parts refer to all products that are neither OEM parts nor genuine parts. For beginners, it is not recommended to choose aftermarket parts. There are quality differences between OEM parts and aftermarket parts: OEM parts are more reliable in terms of compatibility and quality, but they are difficult to find in the market. The quality of aftermarket parts varies, but there are also high-quality products available.

What is the difference between 98 and 95 gasoline?

The differences between 98 and 95 gasoline are as follows: The octane number is different: the higher the gasoline grade, the higher the octane number, and the higher the octane number, the better the stability of the gasoline. Suitable for different models: 98 gasoline is suitable for high-end luxury cars and high-horsepower sports cars, while 95 gasoline is suitable for the vast majority of cars. Information about gasoline is as follows: Gasoline: It appears as a transparent liquid, is flammable, with a distillation range of 30°C to 220°C. The main components are C5~C12 aliphatic hydrocarbons and cycloalkanes, as well as a certain amount of aromatic hydrocarbons. Gasoline has a high octane number (anti-knock combustion performance). Classification: According to the octane number, it is divided into grades such as 90, 93, 95, 97, etc.

Can You Stop the Car Directly by Braking in Second Gear?

You can stop the car directly by braking in second gear. The specific details are as follows: Reason: The car can stop directly in any gear, but the sequence of pressing the brake and clutch differs. Note: Except for first gear, if the speed drops below 10 km/h without pressing the clutch, it will cause gear dragging. Information about car gears is as follows: Gears: Generally, automatic transmission gears are divided into P, R, N, D, 2, 1, or L, etc. P gear: Used for parking, it utilizes a mechanical device to lock the rotating parts of the car, preventing movement. N gear: Neutral. When the lever is placed in "N" gear, the power between the engine and the transmission is cut off. For short stops, the lever can be placed in this gear, and the handbrake can be pulled, allowing the right foot to move away from the brake pedal for a brief rest.

What to Do When the Dashboard Doesn't Light Up but the Car Can Start?

The possible reasons for the dashboard not lighting up include: failure or damage of the dashboard illumination light; open circuit in the dashboard power supply wire; blown fuse of the dashboard power supply. Checking these aspects can help troubleshoot and resolve the issue. Here are some precautions: Regular maintenance of the dashboard: Avoid using rough or hard cloths or fingers to touch the dashboard casually to prevent fingerprints, scratches, and abrasions. It is advisable to prepare appropriate specialized cleaning supplies and perform regular maintenance on the dashboard. Applying an anti-scratch protective film: You can also try applying an anti-scratch protective film on the dashboard screen. There are various types of dashboard protective films available, and it is recommended to choose a static cling film without adhesive on the back. If the film is applied incorrectly, it can be removed and reapplied without causing any damage to the dashboard screen, and it can also prevent accidental scratches during future cleaning.
