Should LED double-sided lights be placed horizontally or vertically?

LED double-sided lights should be placed vertically. Here is some relevant information: 1. LED automotive lights are suitable for various lighting applications in automotive electronics, including headlights (high beam and low beam), fog lights, tail lights, brake lights, turn signals, daytime running lights, pedal lighting, instrument panel lights, license plate lights, door lights, interior lighting, position lights, navigation, entertainment systems, backlighting, and indicator lights. 2. Advantages of LED automotive lights: Energy-saving: LED lights convert electrical energy directly into light energy, consuming only 1/10 of the electricity used by traditional automotive bulbs, which helps save fuel and protects the car's electrical circuit from damage caused by excessive load current. Environmental protection: The spectrum of LED lights contains no ultraviolet or infrared rays, generates little heat, produces no radiation, has minimal glare, and the waste is recyclable. They are mercury-free, non-polluting, safe to touch, and represent a typical green lighting source.

Can I drive with hazard lights on the emergency lane if my car breaks down?

When driving on highways, motor vehicles are not allowed to drive or park on the emergency lane unless under emergency situations. There are two types of emergency situations: 1. When a motor vehicle is involved in a traffic accident or experiences a breakdown and genuinely needs to stop to await rescue, it may temporarily park in the emergency lane; 2. The emergency lane is reserved for police cars, fire trucks, ambulances, and engineering rescue vehicles when performing urgent tasks. If your car breaks down and you need to use the emergency lane, you should first call the police to explain the situation. Additional information: 1. For vehicles involved in accidents or experiencing malfunctions, after entering the emergency lane, they must set up warning signs 100 to 150 meters behind the vehicle and activate hazard warning lights as required. At night, width markers and tail lights must also be turned on. 2. Both emergency stopping belts and emergency lanes are temporary parking zones for vehicles that experience sudden malfunctions or need to stop urgently for other reasons.

What Causes Engine Shaking During Cold Starts?

Engine shaking during cold starts can be attributed to the following reasons: 1. Incorrect air-fuel mixture ratio, where the fuel-air mixture is improperly calibrated, occurring in both open-loop and closed-loop control systems. In vehicles with closed-loop control, the oxygen sensor operates at 370 degrees Celsius; 2. Carbon buildup on valves and intake ports. If carbon deposits form on the engine's valves and intake ports, they can absorb a certain amount of fuel, leading to incorrect ECU judgments; 3. Uneven cylinder conditions. After prolonged engine use, the clearance between each cylinder liner and piston may vary, with larger clearances allowing some high-temperature gases to leak, reducing power output; 4. Faulty coolant temperature sensor. If the engine starts at -10 degrees Celsius but the sensor reports 20 degrees Celsius to the ECU, the ECU will inject fuel based on 20-degree conditions, resulting in insufficient fuel and causing shaking.

Does the Vios come with airbags?

The Vios is equipped with airbags. For the Toyota Vios models, the mid-to-low trim levels come standard with driver and front passenger airbags, while the high-end trim adds two front side airbags, totaling four airbags. Content expansion: 1. The electronic control safety airbag system is a passive safety protection system (see vehicle safety performance). When used in conjunction with seat belts, it provides effective collision protection for occupants. In the event of a car collision, airbags can reduce head injuries by 25% and facial injuries by approximately 80%. 2. While driving, the sensor system continuously sends speed change (or acceleration) information to the control unit. The control unit (central controller) analyzes and evaluates this data. If the measured acceleration, speed change, or other indicators exceed predetermined values (indicating an actual collision), the control unit sends an ignition command to the gas generator, or the sensor directly controls ignition. After ignition, an explosive reaction occurs, producing N2 or releasing compressed nitrogen from a storage tank to inflate the airbag. When occupants come into contact with the airbag, the damping through the airbag's exhaust holes absorbs collision energy, achieving the goal of protecting the occupants.

What is the working principle of a car transmission?

Here is a related introduction to the working principle of a car transmission: 1. The working principle of a manual transmission is to shift the active gear on the intermediate shaft by moving the gear lever, combining gears of different sizes with the power output shaft to change the torque and speed of the driving wheels. 2. An automatic transmission uses a planetary gear mechanism for shifting. It automatically changes gears based on the degree of the accelerator pedal and changes in vehicle speed. The driver only needs to operate the accelerator pedal to control the speed. The introduction to transmissions is as follows: 1. Transmissions are divided into manual and automatic types. Manual transmissions mainly consist of gears and shafts, achieving speed and torque changes through different gear combinations. 2. There are four common types of automatic transmissions for cars: Hydraulic Automatic Transmission (AT), Continuously Variable Transmission (CVT), Automated Manual Transmission (AMT), and Dual-Clutch Transmission (DCT). Currently, AT is widely used in cars and has almost become synonymous with automatic transmissions. The automatic transmission AT is composed of a torque converter, planetary gears, and a hydraulic control system, achieving speed and torque changes through hydraulic transmission and gear combinations.

Can I use a temporary ID for the Subject 2 test if I lost my ID card?

A temporary ID card can be used for the Subject 2 test. However, if you need to use a temporary ID due to the absence of your regular ID, you must inform the driving test instructor in advance and follow the driving school's arrangements for the test. According to Article 19, Paragraph 1 of the "Regulations on the Application and Use of Motor Vehicle Driving Licenses," "first-time applicants for a motor vehicle driving license shall fill out an application form and submit the applicant's identity proof." Therefore, you can take the Subject 2 test with a temporary ID. Additionally, it's important to note that the validity period of a temporary resident ID is three months. You can take the Subject 2 test within this validity period, but you will not be allowed to enter the test site if the ID has expired. Therefore, make sure to take the test within the validity period of the temporary ID. If the temporary ID expires due to special circumstances, you should promptly apply for a replacement of your regular ID or a new temporary ID. Subject 2, also known as the small road test, is part of the motor vehicle driving license assessment. It refers to the field driving skills test. For small vehicles (C1 and C2), the test items include five mandatory components: reverse parking, parallel parking, stopping and starting on a slope, right-angle turns, and curve driving (commonly known as the S-curve). Some regions may include a sixth item, such as high-speed card collection. According to Article 25 of the "Regulations on the Application and Use of Motor Vehicle Driving Licenses" (Ministry of Public Security Order No. 123), as of June 1, 2021, the stopping and starting on a slope test item is no longer required for C2 and C5 license applicants in Subject 2. For large vehicle licenses (A and B), Subject 2 includes 16 items: reverse parking, passing continuous obstacles, curve driving, highway simulation test, width-limited gate, bumpy road, single-plank bridge, narrow road U-turn, stopping and starting on a slope, parallel parking, highway emergency handling, mountain road simulation, right-angle turns, rain and fog weather simulation, highway tire blowout, and tunnel simulation driving.
