Differential consists of left and right axle gears, two planetary gears, and a gear carrier. The differential is a mechanism that allows the left and right or front and rear drive wheels to rotate at different speeds. The main function of the differential is to enable the left and right wheels to roll at different speeds when the car is turning or driving on uneven roads, ensuring that both drive wheels perform pure rolling motion. The differential is installed to adjust the speed difference between the left and right wheels. In four-wheel drive, to drive all four wheels, it is necessary to connect all the wheels. If the four wheels are mechanically connected together, the car cannot rotate at the same speed when driving on curves. To allow the car to maintain basically consistent rotational speed during curve driving, a center differential is required to adjust the speed difference between the front and rear wheels.

What are the functions of the S gear and L gear in the tenth-generation Accord?

The L gear in the tenth-generation Accord can be used to control vehicle speed, enhance traction during uphill driving with heavy loads, or when driving on muddy terrain. The S gear, on the other hand, is designed for overtaking and acceleration, fully unleashing the engine's power. Other differences between the S gear and L gear in the tenth-generation Accord are as follows: 1. Different in nature: The L gear is a low-speed gear, while the S gear is a sport mode. 2. Different characteristics: In S gear sport mode, the transmission delays upshifting, keeping the engine at higher RPMs for an extended period. This allows the car to maintain low gear and high RPM for better torque output and acceleration. When the L gear is engaged, the car will not upshift and continues to move forward at high RPM and low gear, which is more effective for towing cargo.

What Symbol Shows When the Car Battery is Dead?

When the car battery is dead, the battery indicator light on the dashboard will flash continuously, entering an alarm state. The battery indicator symbol is shaped like a battery, with a plus sign on one side and a minus sign on the other. Here are some methods to prevent the battery from dying: 1. Turn off the lights and car electronics before shutting off the engine; 2. Turn off the air conditioning before shutting off the engine; 3. Avoid frequently starting the vehicle. Below are detailed methods to prevent the battery from dying: 1. Turn off the lights and car electronics before shutting off the engine: Before parking and turning off the engine, make sure to turn off the interior lights and avoid using electronic devices such as the CD player or cigarette lighter when the engine is off. Also, minimize the use of various car electronics while driving. 2. Turn off the air conditioning before shutting off the engine: Many drivers are accustomed to leaving the air conditioning on or letting it start automatically with the vehicle. This causes the air conditioning system to engage immediately after ignition, increasing its workload and placing an excessive instantaneous power load on the battery, which can lead to wear and tear. 3. Avoid frequently starting the vehicle: Each engine start should not exceed 3 seconds. If the first attempt fails, avoid repeated starts. The interval between subsequent attempts should be at least 5 seconds.

What is the Tax Standard for Motorcycles?

The tax standard for motorcycles is as follows: motorcycles with an engine displacement exceeding 150cc are subject to a 10% tax rate, while motorcycles with an engine displacement not exceeding 150cc and electric motorcycles are exempt from vehicle purchase tax. Below is a detailed introduction regarding motorcycle taxation. Tax calculation based on taxable price: The taxable price serves as the basis for tax calculation when purchasing a vehicle. The taxable price includes the total price paid by the owner to the dealer and any additional fees, excluding value-added tax (VAT). Generally, the invoice for vehicles sold in the market includes the VAT-inclusive price, so 17% VAT must be deducted when calculating the purchase tax. Tax payment location and procedures: Taxpayers must declare and pay the tax at the local competent tax authority within 60 days from the date of purchase. Required documents include the owner's identity proof, vehicle price proof, and vehicle qualification proof.

When to Use Turn Signals for Right-Angle Turns?

Turn on the left turn signal before making a right-angle turn and turn it off after completing the turn. The turn signal is a crucial set of lights in a vehicle, as it alerts surrounding vehicles and pedestrians, thereby enhancing driving safety. Detailed instructions on using turn signals: Left turn signal: Turn on the left turn signal in advance when making a left turn, changing lanes to the left, preparing to overtake, leaving a parking spot, or making a U-turn. Right turn signal: Turn on the right turn signal in advance when making a right turn, changing lanes to the right, returning to the original lane after overtaking, or parking by the roadside. Liability in accidents: If an accident occurs due to the driver's failure to use turn signals, the driver is highly likely to bear primary or full responsibility for the accident. Principle of turn signals: Utilizing the thermal effect of electric current, the expansion and contraction caused by heat drives the spring to produce abrupt movements, thereby connecting and disconnecting the contacts to achieve light flashing. The resistance wire type can be further divided into thermal wire type (electrothermal) and wing type (spring-action), while the electronic type can be categorized into hybrid (relay with contacts and electronic components) and fully electronic (without relays). For example, the spring-action flasher,

Can the Battery Be Charged While Idling in Place?

Yes, a car can charge its battery while idling in place. Idling refers to the engine running without any load, with the gear in neutral—a state often described as "working without output." Although the vehicle consumes fuel without moving or performing work, it can still charge the battery. However, idling consumes a significant amount of fuel and produces severe emissions pollution, so it is recommended to use a battery charger instead. Below are some precautions for charging the battery while idling: 1. Avoid using other power-consuming devices: If the car battery is low on charge and you turn on high-power devices like the air conditioner, high beams, or car audio system while idling, it may exceed the generator's maximum output, leading to permanent battery damage. 2. There's no need to rev the engine: Some suggest that revving the engine to increase RPM can speed up charging efficiency. In reality, as long as you avoid using high-power devices like the air conditioner while idling, revving the engine is completely unnecessary.

How to check traffic violations on the same day?

Traffic violations cannot be checked on the same day; they generally become available within two business days to one week. Here's an introduction to vehicle violation inquiries: 1. Violation capture: Violations need to be confirmed before being uploaded to the traffic police internal network. The upload time varies depending on the violation location, behavior, and penalty method. Currently, there is no precise time interval record. The traffic management network exchanges data with the traffic police internal network every night. Once confirmed and uploaded, violations can be checked on the traffic management network within two business days. 2. Camera-captured violations: Non-on-site violations (those captured by cameras) take about 15 days to appear in the system. The time varies by region, usually around one week. If you're concerned about potential violations, you can check online one week after the incident. For more certainty, check again after 15 days. Additionally, vehicle owners can subscribe to SMS notification services on their local traffic management bureau website, typically receiving fine notices the next day.
