6-dzf-20.2 means respectively: 6 refers to the number of battery cells, each cell is 2V, 6 cells make 12V; DZF stands for electric; 20 indicates the rated capacity is 20Ah. Introduction to batteries: A battery is a type of storage cell, also called an accumulator, which works by converting chemical energy into electrical energy. The battery commonly referred to is a lead-acid battery, which mainly uses lead and its oxides as electrodes and a sulfuric acid solution as the electrolyte. Types of batteries: A battery refers to a type of cell that can be recharged and reused after discharge. These include lead-acid batteries, nickel-iron batteries, and nickel-cadmium batteries. The positive electrode of a lead-acid battery is lead dioxide, the negative electrode is lead, and the electrolyte is a dilute sulfuric acid solution. During discharge, the positive and negative electrodes react with sulfuric acid to form lead sulfate. When the concentration of the sulfuric acid solution drops to a certain level, the battery must be recharged.

What are the reasons for the trunk not closing without applying force?

The reasons for the trunk not closing without applying force are as follows: 1. Overly stiff spring rods: To ensure the rear hatch automatically lifts when the opening switch is pressed, excessively stiff spring rods are used; 2. Rubber stops and locking mechanism: The rubber stops and locking mechanism are not properly matched; 3. Control circuit: Malfunction in the trunk control circuit; 4. Hydraulic support rods: Failure in the trunk hydraulic support rods. In fact, when facing a trunk that won't close, applying force will only cause more damage. The correct approach is to drive the vehicle to a repair shop for inspection. The trunk is used for daily transportation, and during travel, it often carries a large number of items. This easy-to-maintain trunk compartment is even suitable for storing food and beverages.

What does N mean in an automatic transmission?

In an automatic transmission, N stands for Neutral. The N position is equivalent to neutral gear, which can be used during startup, when parking with the driver remaining in the vehicle, or when towing. When the gear lever is in this position, the transmission idles, and the engine power cannot be transmitted to the drive wheels, providing no driving or braking force to the wheels. An automatic transmission refers to a system where the driver does not need to manually shift gears; the vehicle automatically selects the appropriate gear based on driving speed and traffic conditions. Typically, an automatic transmission has six gear positions: P (Park), R (Reverse), N (Neutral), D (Drive), S (Sport), and L (Low). Automatic transmissions use planetary gear mechanisms to shift gears automatically based on the degree of throttle pedal input and changes in vehicle speed.

What is the function of the metal baffle in the car experiment?

The initial baffle provides an initial velocity, while the final baffle prevents damage. Here are some precautions regarding car driving: Cold car warm-up: Proper warm-up helps the engine oil form an 'oil film' between engine components, thereby reducing component wear. Timely gear shifting: When driving a manual transmission vehicle during the break-in period, shift gears promptly and appropriately, avoiding incorrect behaviors such as high gear with low RPM or low gear with high RPM, and do not use a single gear for an extended period. Timely maintenance: Simply follow the manufacturer's recommendations in the vehicle manual, and after reaching a certain mileage or time, promptly inspect and maintain the vehicle, including changing the engine oil and oil filter, and conduct a comprehensive inspection of the chassis system. Avoid emergency braking: Emergency braking not only impacts the braking system during the break-in period but also increases the shock load on the vehicle's chassis and engine.

Is it one or two annual inspections for cars after 15 years?

For cars after 15 years, it requires two annual inspections. Here is extended information about annual inspections: New regulations: According to the 2020 regulations, vehicles within 10 years require an inspection every two years. In the motor vehicle inspection reform implemented on November 20, 2020, the scope of motor vehicles exempt from inspection was expanded. On the basis of exempting non-operational mini and micro passenger vehicles with 6 seats or fewer from inspection within 6 years, non-operational mini and micro passenger vehicles with 7 to 9 seats (excluding vans) within 6 years were also included in the exemption range. On-site testing: For non-operational mini and micro passenger vehicles (excluding vans) older than 6 years but less than 10 years, the inspection frequency was adjusted from once per year to once every two years, but on-site testing is still required for the annual inspection.

Where is the center point of an intersection?

It is where the center lines of two roads intersect, usually where traffic police stand to direct traffic. Large intersections typically have a marked point, while smaller ones generally do not. Below is related information about turning at the center of an intersection: 1. When turning left: Vehicles must turn closely around the center point of the intersection. At large intersections, there is usually a circle with diagonal lines inside, which marks the center point—often where traffic police direct traffic. 2. When making a left turn: Proceed near the center point before turning, meaning turning closely to the left side of the center point, also known as making a tight turn. This rule mainly prevents collisions with vehicles on the left. For intersections without markings, the center point is simply the intersection point.
