What are the regulations for window tinting under the 2021 new traffic rules?

2021 new traffic regulations for window tinting stipulate that the visible light transmittance of the front windshield area in the driver's line of sight and the areas used for observing exterior rearview mirrors while driving must be greater than or equal to 70%. Window glass visible light transmittance exceeding 50%: For highway buses, tourist buses, buses with passenger standing areas, school buses, and passenger vehicles with mid-mounted engines and a width-to-height ratio ≤0.9, the visible light transmittance of all window glass must be ≥50%. No reflective materials allowed: Except for safety signs and information symbols on buses that comply with GB30678 standards, no opaque or mirror-reflective materials (including colored or heat-resistant films) should be applied.

What does the ECON switch in a car mean?

ECON stands for the car's fuel-saving mode switch, which can be used to turn the fuel-saving mode on or off. Modern cars generally offer three driving modes to choose from: fuel-saving mode, comfort mode, and sport mode. Below is information about these three modes: Fuel-saving mode: When the car is in this mode, fuel consumption is relatively low, the throttle pedal sensitivity decreases, and the transmission shifts up more aggressively. Comfort mode: This mode can be considered a normal operating mode for the car. In this mode, the throttle pedal response is more sensitive than in fuel-saving mode. Sport mode: This mode can be used during aggressive driving. When sport mode is activated, the throttle pedal response becomes highly sensitive, and the transmission delays shifting. The transmission will only upshift when the engine speed reaches the redline. After switching to sport mode, the engine speed will remain around 3000 RPM, ensuring better power response during acceleration. Activating ECON mode in a car can reduce fuel consumption and save energy, but it may weaken the car's power. ECON can be understood as an abbreviation for 'economy.' It is generally recommended to keep ECON mode enabled in most situations, except when high torque output is required (e.g., climbing a hill) or when driving at very high speeds, in which case ECON mode should be turned off. Pressing the ECON button puts the car into a low-carbon, eco-friendly driving mode. Subsequently, the ECU, engine, and transmission intelligently execute the driver's intentions in the most fuel-efficient manner, achieving optimal fuel economy through rapid upshifts and smooth acceleration. When the driver presses the throttle pedal deeply, the ECON system effectively controls the opening and closing of the intake valves to ensure smooth engine operation and energy savings. Although ECON mode is simple and effective to operate, it may not function under certain conditions: When the vehicle speed exceeds 120 km/h, priority is given to speed, and the fuel-saving mode automatically deactivates. This means that if the speed exceeds the economical range (typically between 60-90 km/h), the ECON mode will not save fuel. The key to ECON mode is its reliance on computer-controlled operation while driving to be effective. Therefore, it does not function when the car is idling, parked, or in neutral (N), park (P), or manual mode. When the car needs to overcome significant resistance and output higher torque, such as when climbing a hill, the ECU prioritizes ensuring sufficient power to drive the car, and ECON mode will not work in such cases.

What Does a Lens Look Like?

An automotive lens is a circular, completely transparent glass body. The light-gathering function of the lens: Because the lens has strong light-gathering capabilities, it is used for road illumination, making the road surface not only bright but also clear. Since the light dispersion is minimal, the light range is farther and clearer than that of ordinary halogen lamps, allowing drivers to see distant objects in time to avoid missing intersections or targets. The energy-saving function of the lens: The HID bulb inside the lens has a lifespan 8 to 10 times longer than that of ordinary bulbs, eliminating the hassle of frequent replacements. The lens xenon lamp does not require any additional power supply system because a genuine HID gas discharge lamp only needs a voltage stabilizer to convert 12V voltage into normal voltage, providing stable and continuous power to the xenon bulb, thus achieving energy-saving functionality.

What should be paid attention to when a car is parked for a long time?

When a car is parked for a long time, the following points should be noted: Keep the car body clean and dry before parking: Carefully check the parts of the car that are prone to water accumulation at the bottom, and remove any accumulated water in time. If parked outdoors, cover the car with a car cover to protect it from direct sunlight and erosion by rain and snow. Park the car in a higher position: The car must be parked in a relatively high place to avoid becoming a flooded car when it rains; in addition, lower places are relatively more humid, and the car body is more prone to rust. Park the car on a relatively flat surface: The car must be parked on a relatively flat surface to keep the suspension system in its normal position and ensure even force distribution on each suspension. If parked on an uneven surface, one of the suspensions may deform, and maintaining this posture for a long time can cause permanent deformation of the suspension system, leading to misalignment of the car wheels.

What does TFSI mean?

TFSI refers to Turbocharged Fuel Stratified Injection engine. Introduction to TFSI: TFSI is the combination of an FSI engine and a turbocharger, where T stands for turbocharging technology, and the following FSI refers to Fuel Stratified Injection engine. TFSI is an engine fuel supply technology where fuel is injected into the cylinders to ensure full combustion and energy release, thereby driving the vehicle. Working principle of turbocharging system: It collects the exhaust from all cylinders of the internal combustion engine into a sufficiently large exhaust pipe, which is then introduced into the turbine. Although the cylinders exhaust alternately, due to the pressure stabilizing effect of the exhaust pipe, the pressure at the turbine inlet remains basically unchanged, hence it is called a constant pressure turbocharging system.

What is the difference between a dash cam and a 360-degree panoramic system?

The differences between a dash cam and a 360-degree panoramic system are as follows: Different functions: The 360-degree panoramic system has three trigger signals - reverse, left turn, and right turn signal lines, enabling forced activation to display corresponding views. It elevates driving, parking, and reversing safety to the highest level, helping prevent accidents. It can deter fraudulent claims, assist novice drivers in parking, and provide 24/7 omnidirectional monitoring. In contrast, a regular dash cam only records footage after an accident occurs. Different monitoring durations: The 360-degree panoramic recorder is directly powered by the car battery, allowing continuous operation even after the engine is turned off, enabling 24-hour recording of post-parking situations. Although some dash cams with built-in batteries also have parking recording functions, their duration is limited by battery capacity, typically recording for a maximum of 1-2 hours. Different viewing angles: The 360-degree panoramic recorder features four cameras that simultaneously record the vehicle's front, rear, left, and right sides, with seamless stitching of the four views. Dash cams are usually mounted on the front windshield, mostly with a single camera, though some models have front and rear cameras, offering fewer viewing angles.
