What is the capacity of a car battery?

Generally, the capacity of household car batteries ranges between 54-60Ah. Car battery capacity refers to the amount of electricity the battery can discharge under certain conditions (discharge rate, temperature, termination voltage, etc.). Functions of a car battery: It supplies power to the starting system, ignition system, and electronic fuel injection system during engine startup; provides power to car electrical equipment when the engine is off or at low idle; acts as a voltage stabilizer for the vehicle's electrical system; and stores excess electrical energy generated by the alternator. Maintenance of a car battery: Avoid parking the car in open parking lots for extended periods. If long-term parking is necessary, remove and take the battery to prevent freezing damage; car batteries should be charged regularly as prolonged disuse leads to gradual self-discharge, eventually causing failure. Therefore, start the car periodically to recharge the battery; clean the battery terminals regularly and apply special grease to protect the wiring harness; frequently inspect battery accessories and connecting circuits; avoid using car electrical appliances after the engine is turned off, as using the battery alone when the engine is not generating electricity can cause damage.

What does NVH mean?

NVH is the English abbreviation for Noise, Vibration, and Harshness. Below is relevant information about automotive NVH: The role of NVH: NVH is a comprehensive issue that measures the manufacturing quality of automobiles, providing the most direct and superficial experience for car users. NVH issues in vehicles are one of the concerns for major automotive manufacturers and component companies in the international automotive industry. Internal relationships of NVH: The generation of automotive vibration and noise is not independent but closely interrelated. It can be said that noise originates from vibration, and these three factors—vibration, noise, and comfort—are closely connected. It is necessary to reduce vibration and noise while improving ride comfort, ensuring product safety, environmental friendliness, and performance. Characteristics of NVH issues: NVH issues are systemic. For example, if a car's cabin noise is loud while driving, and the source is traced back to the engine, this noise problem may involve three aspects: first, the engine itself is noisy; second, the vibration damping effect of the engine mounting components is poor; and third, the sound insulation technology of the cabin front wall and floor is inadequate.

How to Determine if the Drive Shaft Has Problems?

Methods to determine if the drive shaft has problems include: 1. Hearing a clunking sound or feeling mechanical looseness when starting the car or accelerating sharply; 2. A buzzing sound from the chassis while driving, which becomes louder as the speed increases; 3. A knocking sound from the drive shaft when starting the car or shifting gears during driving; 4. Increased noise accompanied by vibrations at higher speeds, with the driver feeling numbness in the hands holding the steering wheel. The drive shaft is a high-speed, minimally supported rotating component that works with the transmission and drive axle to transfer the engine's power to the wheels, generating driving force for the car.

What to Do When the Gear Cannot Be Disengaged?

The inability to disengage the gear is mostly due to problems with the transmission or clutch. This issue is quite complex and must be addressed at a 4S shop or a professional auto repair shop, where experts can diagnose and repair it. Common causes include the following: 1. Loose or missing screws: At the rear of the transmission, there is a shift lever adjustment screw that connects the transmission shift lever to the internal gear-shifting mechanism via two rods, facilitating the adjustment of the shift lever position. If this screw becomes loose or falls out, the shift handle inside the car may move but fail to transmit the action to the transmission, making it impossible to disengage the gear. 2. Excessive meshing force between gears: If the clutch pressure plate is damaged and cannot disengage, the engine continues to supply power to the wheels, causing the gears to tightly mesh and transmit power. Due to the high meshing force, it becomes difficult to disengage the gear. 3. Broken shift lever cable: If the shift lever cable is broken, the response from the shift lever cannot be transmitted to the transmission actuator. The transmission mainly refers to the car's gearbox, which includes manual and automatic types. A manual transmission primarily consists of gears and shafts, achieving speed and torque variation through different gear combinations. An automatic transmission (AT) is composed of a torque converter, planetary gears, a hydraulic torque variation system, and a hydraulic control system, achieving speed and torque variation through hydraulic transmission and gear combinations.

How to Measure the Mileage of a Car?

The method to measure a car's mileage is to check the odometer on the dashboard, which allows the driver to know the distance traveled. The method to reset the car's mileage is: 1. Press the black button next to the vehicle's dashboard; 2. Remove the dashboard and take out the components inside, then adjust the mileage gear using a tool. The car's mileage is calculated based on the number of rotations the tires make, with the calculation performed by sensors and the car's computer, and displayed on the odometer. The car's mileage refers to the total distance the car has traveled, and the number displayed on the dashboard's total mileage odometer represents the car's mileage.

Is going straight in a left-turn lane considered running a red light?

When the straight signal is red, going straight in a left-turn lane is considered running a red light and also constitutes a violation of not following the directional lane markings, resulting in penalties for both offenses. When the straight signal is green, going straight in a left-turn lane is considered a violation of not following the directional lane markings. Red light running penalty standards: According to Article 2, Section 1, Clause 2 of the "Scoring Standards for Road Traffic Safety Violations," driving a motor vehicle in violation of traffic signal lights results in a deduction of 6 points. Article 3, Section 1, Clause 8 states that driving a motor vehicle in violation of prohibition signs or markings results in a deduction of 3 points. How to check for red light running violations: Common methods include the following: You can check for red light running violations through the "Traffic Management 12123" app. After opening the app, log in using your ID card, then find and click on the "Violation Handling" option. Under "Violation Handling," you can view the current status of your vehicle. If there are any violations, the specific details will be displayed. You can also check by visiting the service halls of local traffic police branches and using the touch-screen query terminals. Alternatively, log in to the external service website of your city's Public Security Bureau Traffic Management Bureau, find the "Vehicle Violation Query" section, enter your license plate number and vehicle engine number, and click "Query."
