What Components Make Up a Car Audio System?

What is the reason for a thud sound in the trunk after braking to a stop?

The reason for a thud sound in the trunk after braking to a stop is: the gap between the brake pads and the brake caliper is too large, and it needs to be checked at a professional repair shop. It could be normal brake pad wear noise, or there might be damage in the suspension system. Braking is achieved through intense friction between the brake pads and the brake drum. The principle involves fixing a wheel or disc on the high-speed shaft of the machine and installing a corresponding brake shoe, belt, or disc on the machine base, which generates braking torque under external force. The car brake pedal is located below the steering wheel. Pressing the brake pedal causes the brake lever to be pressurized and transmitted to the brake pads on the brake drum, clamping the brake disc to slow down or stop the car.

How many points are deducted for a pickup truck's rear door left open?

Leaving a pickup truck's rear door open is not illegal, but it becomes illegal if it obstructs the license plate. If you must keep the tailgate open for cargo transport, you can make an enlarged license plate number using cardboard or wood and hang it clearly with legible writing. Currently, there are several ways to check traffic violations: Online traffic violation query: Vehicle owners can search "vehicle violation" (or directly search "vehicle violation [location]") on Baidu or check the "Practical Query" section on comprehensive websites like hao123. Enter the query system (usually local public security traffic police websites) and search by region, generally requiring input of the license plate number and vehicle identification number (usually the last 4 or 6 digits of the VIN). Some regions may require registration for future convenient login queries. Phone call traffic violation query: Many regional traffic police websites list a free traffic violation inquiry phone number for checking violations. Alternatively, you can call 114 for traffic violation inquiries.

How many more points can be deducted with 8 cumulative points?

Cumulative deduction of 8 points refers to the accumulated penalty points on a driver's license, and 4 more points can still be deducted. Below is more relevant information: Scoring cycle: As long as the cumulative points within one scoring cycle (one year from the date of initial license issuance) do not exceed 12 points, after paying the fine, the system will reset the points from the previous scoring cycle at the start of the next cycle. Driver's license points: Points on a driver's license are penalties for traffic violations. Depending on the severity of the violation, points can range from a minimum of 1 to a maximum of 12 per violation. One scoring cycle equals one inspection period. If a driver accumulates 12 points in one cycle, they lose their driving privileges and must undergo at least 7 days of traffic safety education. Only after passing the exam can their driving privileges be restored. Passing the exam: Points will be cleared, and the driver's license will be returned. Failing the exam: The driver must continue studying and retaking the exam. Refusing to study or take the exam will result in the traffic management department of the public security authority announcing the suspension of the driver's license.

How long does it take to charge a 12V car battery?

How long it takes to charge a 12V car battery depends on the charging current. The specific time is as follows: 1. Generally, the battery retains more than 20% of its charge, and the chemical conversion efficiency during charging is about 50%. To fully charge the battery, it requires an additional 150%*80% of the charge. 2. The optimal charging current for the battery is 10% of its capacity. However, the charging time required is 150%*80%/10%=12 hours, plus about 1 hour for the additional time needed for segmented charging. 3. To align with people's daily routines, a charging current of 13% of the battery's capacity is usually designed, resulting in a charging time of at least 150%*80%/13%=9.2 hours, plus about 1 hour for the additional time needed for segmented charging. 4. For fast charging, a current of 20% of the battery's capacity is typically used, with a charging time of 150%*80%/20%=6 hours. Using a higher current can shorten the charging time, but it may damage the battery, so it should be used with caution.

What is the fuel tank capacity of the Fit?

The 2021 Honda Fit has a total of 6 models, all with a fuel tank capacity of 40 liters. The vehicle is equipped with a continuously variable transmission (CVT) and features front-wheel drive. Among vehicles in the same class, the 2022 Polo has a fuel tank capacity of 42.5 liters, the 2022 YARiS L Zhi Xuan has a capacity of 42 liters, and the 2022 Vios also has a capacity of 42 liters. During actual refueling, the amount of fuel 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 safe fill level. There is additional space from the safe fill level to the tank opening, which is designed to allow for fuel expansion when temperatures rise, preventing overflow. If fuel is filled up to the tank opening during refueling, the actual amount of fuel added may exceed the marked capacity. To check the remaining fuel level, observe the fuel gauge on the right side of the instrument panel, which is marked with E and F. When the needle is near E, it indicates low fuel, and when it is close to F, it indicates sufficient fuel.
