The auto light on a car refers to the automatic headlights. Here is more information about auto lights: 1. The headlights will automatically turn on or off based on the light sensing system, enabling automatic activation/deactivation as well as automatic switching between high and low beams. When the light control is set to this position, the lights won't illuminate during daytime but will automatically activate at night, such as when driving through tunnels, on cloudy days, or in any dimly lit areas. 2. The working principle of auto lights is: Electronic components like photoresistors act as sensors to send electronic signals to the ECU, informing it whether to turn the headlights on/off, after which the ECU controls the headlight switch and high/low beam changes.

Why does a scooter motorcycle experience weak acceleration and sputtering?

The reasons for weak acceleration in a scooter motorcycle are: Fuel system malfunction: An excessively lean air-fuel mixture results in insufficient gas pressure on the piston after ignition; an overly rich mixture causes weak acceleration at low speeds; a clogged air filter or an excessively high carburetor float level. Decreased engine compression ratio: Engine power is directly related to the compression ratio. With prolonged use, internal engine components wear out. If key components become excessively worn, the engine's compression ratio will decrease. Transmission system malfunction: Clutch slippage can severely reduce the vehicle's acceleration performance. To troubleshoot this issue, start with external inspections. First, check the engine's combustion condition, then adjust the carburetor accordingly based on the combustion performance. If the improvement is not significant, inspect the ignition system according to the symptoms. If the problem persists after these steps, disassemble the engine for further inspection.

What are the new regulations for annual vehicle inspection effective July 1, 2021?

The new regulations for annual vehicle inspection effective July 1, 2021 involve the cancellation of six inspection items, expansion of the six-year exemption scope, and optimization of inspection cycles. Detailed explanation of the new regulations: 1. Cancellation of six inspection items: These include power performance testing, speedometer error testing, interior noise testing, electronic parking brake testing, headlight offset testing, and suspension testing. 2. Expansion of the six-year exemption scope: The exemption now covers 7-9 seat vehicles within six years (excluding minivans). Building upon the existing exemption for non-commercial mini and micro passenger vehicles with fewer than 6 seats within 6 years, the scope is further expanded to include non-commercial mini and micro passenger vehicles with 7-9 seats (excluding minivans). 3. Optimization of inspection cycles: Private vehicles only need to undergo on-site inspection twice within 10 years. For non-commercial mini and micro passenger vehicles (excluding minivans) older than 6 years but less than 10 years, the inspection cycle is extended from annual to biennial inspections. This means private vehicles only require on-site inspections in the 6th and 8th years within the first 10 years. For vehicles older than 15 years, the rules remain unchanged, requiring semi-annual inspections. Annual inspection precautions: Check for any traffic violation records and handle them promptly; Ensure the trunk contains a fire extinguisher and warning triangle; Replace license plates in advance if they show damage, wear, or fading; Remove any added accessories like running boards or strobe lights, and revert modified wheel hubs to original; For vehicles with 7 or more seats (like minivans), ensure all seats are properly installed to match the number on the vehicle registration, with functional seat belts for each seat.

What is the fuel tank capacity of the Buick Verano in liters?

The fuel tank capacity of the Buick Verano is 44 liters, as officially announced. Owners who have purchased the Buick Verano can also check this information on the vehicle's configuration sheet. The Buick Verano requires 92-octane fuel, with a fuel consumption of 5.8 to 6.3L per 100 kilometers. A full tank can cover a distance of 698 to 759 kilometers. During daily driving, it is essential to monitor the remaining fuel level in the tank. This is typically done by observing the fuel gauge inside the vehicle. Under normal circumstances, the fuel level will be accurately reflected on the gauge. The fuel gauge usually has 5 to 6 segments, and it is advisable to refuel when only 2 segments remain to avoid running out of fuel midway. During actual refueling, the amount of fuel added may exceed the marked capacity. This is because the fuel tank capacity specified by the manufacturer is measured from the bottom of the tank to the safety limit. There is additional space from the safety limit to the tank opening, which is designed to allow for fuel expansion due to temperature increases without causing overflow. If fuel is added up to the tank opening during refueling, the actual amount of fuel added may exceed the marked tank capacity.
